Configuring Cypress, cypress-react-unit-test, and React : <p>I want to test our React components independently using the package <code>cypress-react-unit-test</code>. After several days, I have been unable to get it to work with the existing React Webpack configuration.
I get the error: <code>TypeError: path argument is required to res.sendFile</code> when I open the file through Cypress' window.</p>
<p>I am using the file from their example repo for testing:
<a href="https://github.com/cypress-io/cypress-example-recipes/blob/master/examples/unit-testing__react/greeting.jsx" rel="noreferrer">https://github.com/cypress-io/cypress-example-recipes/blob/master/examples/unit-testing__react/greeting.jsx</a></p>
<p>We do use TypeScript, but I wanted to get this working first.</p>
<p>I have tried overwriting <code>path</code> as it is defaulting to <code>undefined</code>, but I'm getting the same error.</p>
<pre><code>{
options: {
path: "/my/home/dir/"
}
}
</code></pre>
<p>In my <code>cypress/plugins/index.js</code> file I have:</p>
<pre><code>const wp = require("@cypress/webpack-preprocessor");
const webpackConfig = require("../../node_modules/react-scripts/config/webpack.config")("development");
module.exports = on => {
const options = {
webpackOptions: webpackConfig
};
on("file:preprocessor", wp(options));
};
</code></pre>
<p>I'm obviously missing something, but I don't know Webpack well enough. I would be grateful for any pointers! Thanks!</p>

Tensorflow Precision / Recall / F1 score and Confusion matrix : <p>I would like to know if there is a way to implement the different score function from the scikit learn package like this one :</p>
<pre><code>from sklearn.metrics import confusion_matrix
confusion_matrix(y_true, y_pred)
</code></pre>
<p>into a tensorflow model to get the different score.</p>
<pre><code>with tf.Session(config=tf.ConfigProto(log_device_placement=True)) as sess:
init = tf.initialize_all_variables()
sess.run(init)
for epoch in xrange(1):
avg_cost = 0.
total_batch = len(train_arrays) / batch_size
for batch in range(total_batch):
train_step.run(feed_dict = {x: train_arrays, y: train_labels})
avg_cost += sess.run(cost, feed_dict={x: train_arrays, y: train_labels})/total_batch
if epoch % display_step == 0:
print "Epoch:", '%04d' % (epoch+1), "cost=", "{:.9f}".format(avg_cost)
print "Optimization Finished!"
correct_prediction = tf.equal(tf.argmax(pred, 1), tf.argmax(y, 1))
# Calculate accuracy
accuracy = tf.reduce_mean(tf.cast(correct_prediction, "float"))
print "Accuracy:", batch, accuracy.eval({x: test_arrays, y: test_labels})
</code></pre>
<p>Will i have to run the session again to get the prediction ?</p>

Clean Architecture - how to address database transactions? : <p>In 'clean architecture' the interactors (use cases) are responsible for defining busines logic. Most of the examples define use cases in such a way:</p>
<pre><code>public MyUseCase() {
public boolean execute(...) {
int id = repository.insert(a)
if(id > 0) {
b.aId= id;
repository.insert(b);
...
}
}
}
</code></pre>
<p>Interactors use mostly simple CRUD like operations or queries on repository.
The above example is synchronous for the case of simplicity but you can find repos with the same approach using asynchronous solutions like callbacks or rxjava.</p>
<p>But what about use case inegrity. For instance, you can't be 100% sure that after inserting <code>a</code> it will still be there when you insert <code>b</code>.
What if after inserting <code>a</code> you get some RepositoryException while inserting <code>b</code>.</p>
<p>All the repos I've seen so far don't take it into account, so my question is:</p>
<p>What's the solution of the above problem in clean architecture?</p>

Retrieving data from Firebase Android Studio : My Database looks like this
[Firebase Databse][1]
[1]: https://i.stack.imgur.com/gab3H.png
The code of my activity is this
public class FirebaseActivity extends AppCompatActivity {
ListView lv;
private FirebaseDatabase database;
private DatabaseReference myRef;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_firebase);
final List<String> glocations = new ArrayList<String>();
lv = (ListView) findViewById(R.id.lv);
database = FirebaseDatabase.getInstance();
myRef = database.getReference();
myRef.child("Users").addValueEventListener(new ValueEventListener() {
@Override
public void onDataChange(DataSnapshot dataSnapshot) {
Iterable<DataSnapshot> children = dataSnapshot.getChildren();
for (DataSnapshot child: children){
String data = child.getValue(String.class);
glocations.add(data);
}
}
@Override
public void onCancelled(DatabaseError databaseError) {
}
});
ArrayAdapter<String> adapter = new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1,glocations);
lv.setAdapter(adapter);
}
}
Now whenever I try to open the activity from the settings menu on the main activity my application crashes. All I want it to do is show the Latitude, the longitude and the timestamps each time the user changes them in a listview by using a simple list with the array adapter.
This is a different activity and not the main one. The main one works perfectly. I've watched countless videos and I cannot understand my mistake.

If I have N distinct points, how many different ways can I construct a set of distinct points? : <p>Lets say that I have 2 groups of distinct points. I'm trying to find all the possible different ways to travel between these points. In one group we have P1,P2 and in the other group P3,P4. Any point can be a starting point and can only end in the opposing group. I want to find a way to formalize how to find all combinations of these points. Each group can have an N distinct number of points, but I chose for each group to have 2 points. These are all the possible set of points from these two groups: </p>
<ul>
<li>Set 1: P1->P2->P3->P4</li>
<li>Set 2: P1->P2->P4->P3</li>
<li>Set 3: P2->P1->P3->P4</li>
<li><p>Set 4: P2->P1->P4->P3 </p></li>
<li><p>Set 5: P3->P4->P2->P1</p></li>
<li>Set 6: P3->P4->P1->P2</li>
<li>Set 7: P4->P3->P2->P1</li>
<li>Set 8: P4->P3->P1->P2</li>
</ul>
<p>The "->" denotes a path traveled. Therefore I have 8 distinct paths traveled. How do I formalize this though? I've tried thinking of exponents, and factorials... I'm a bit stuck right now.</p>

Maze won't backtrack [Python] : There are a couple of maze questions similar to this one but none of them ever really go into the why it won't work.
This is for an assignment for my summer class. I don't need precise answers. I just need to know why this particular thing doesn't work.
This is the bit of my class Maze that I need help with.
ysize in my example is 10
xsize is 10
xend is 20 (changing it to 19 messes with the results and doesn't draw anything)
yend is 10 (changing it to 9 does this too)
'''
def solve(self, x, y):
if y > (self.ysize) or x > (self.xsize):
print("1")
return False
if self.maze[y][x] == self.maze[self.yend][self.xend]:
print("2")
return True
if self.maze[y][x] != " ":
print("3")
return False
self.maze[y][x] = "o" # MARKING WITH o for path already taken.
if self.solve(x+1,y) == True:
return True
elif self.solve(x,y+1) == True:
return True
elif self.solve(x-1,y) == True:
return True
elif self.solve(x,y-1) == True:
return True
self.maze[y][x] = " " # ELSE I want it to be replaced with space
return False
'''
The expected result is the solved maze with a trailing path of "o" from 1 1 to 9 19 as per the current file.
However what I get is a path from 1 1 to 13 4 (x)(y) format.
There is a dead end around 13 4 and it won't backtrack to go up and left. Sorry if it doesn't make that much sense but copy pasting the drawing doesn't turn out well.

asterisk stream asr plugin : <p>Is there any plugin/extension for Asterisk that is able to make ASR(automatic speech recognition) in stream mode and is able to use Google/Yandex speech kits? So, speech should be recognized in "online" mode, during the call. Russian language and language detection(at leat russian|not russian) should be supported. Main idea is that no programming should be required. And yes, I've heard about MRCP, but nothing clear about how to use it with Google/Yandex. And it should be free/open source.
Thanks!</p>

brute force Structure code in c# for bus reservation : I'm working on bus ticket reservation system. I have a problem in the booking module.
Say we have bus a route starts from "A" to "D" via "B" & "C"
The bus starts from "A" then reach "B", then "C" and final destination is "D".
Assume some one is reserving seat no "1" for "B" to "C", this seat no should not be available for the person who is searching for a seat to travel from "A" to "D" or "B" to "D" but the same seat should be available for "A" to "B" or "C" to "D"
Example in Summary
Seat No 1 is Reserved for "B" to "C"
Seat No 1 should not be available for "A"-"D"
Seat No 1 should not be available for "B"-"D"
Seat No 1 should not be available for "B"-"C"
Seat No 1 should be available for "A" to "B"
Seat No 1 should be available for "C" to "D"
Could you please if there is already an algorithm or dotnet c# code to solve this problem.
Thanks in advance

<p>content inside the sample file is like this</p>
<pre><code>#helloworld
export a=foo
export b=hello
#helloworld2
export c=king
export d=queen
</code></pre>
<p>the expected output should remove #(commented lines), export words and empty lines, the output should be like this. </p>
<pre><code>a=foo
b=hello
c=king
d=queen
</code></pre>
<p>and also it should rename the file in the same folder on the fly.</p>
<pre><code>./folder/rename-sample
</code></pre>
<p>Please let me know how to achieve this using proper SED command.</p>

Pipe and Tap VS subscribe with ngxs : <p>I am playing around with pipe and subscribe. If I am using pipe with tap, nothing will log in console. If I am using subscribe, it's working. So what I am doing wrong?</p>

this.store.select(state => state.auth.authUser).pipe(

What happens when the Kubernetes master fails? : <p>I've been trying to figure out what happens when the Kubernetes master fails in a cluster that only has one master. Do web requests still get routed to pods if this happens, or does the entire system just shut down?</p>
<p>According to the OpenShift 3 documentation, which is built on top of Kubernetes, (<a href="https://docs.openshift.com/enterprise/3.2/architecture/infrastructure_components/kubernetes_infrastructure.html" rel="noreferrer">https://docs.openshift.com/enterprise/3.2/architecture/infrastructure_components/kubernetes_infrastructure.html</a>), if a master fails, nodes continue to function properly, but the system looses its ability to manage pods. Is this the same for vanilla Kubernetes?</p>

High Presicion Random Double Numbers : This is a follow up question on an answer on this page:
[How to generate random double numbers with high precision in C++?][1]
#include <iostream>
#include <random>
#include <iomanip>
int main()
{
std::random_device rd;
std::mt19937 e2(rd());
std::uniform_real_distribution<> dist(1, 10);
for( int i = 0 ; i < 10; ++i )
{
std::cout << std::fixed << std::setprecision(10) << dist(e2) << std::endl ;
}
return 0 ;
}
The answer works fine but I had a hard time to reliaze how to put the output of this code in a double variable instead of printing it on the STDOUT. Can anyone help with this?
Thanks.

Swift 3 method to create utf8 encoded Data from String : <p>I know there's a bunch of pre Swift3 questions regarding NSData stuff. I'm curious how to go between a Swift3 <code>String</code> to a utf8 encoded (with or without null termination) to Swift3 <code>Data</code> object.</p>
<p>The best I've come up with so far is:</p>
<pre><code>let input = "Hello World"
let terminatedData = Data(bytes: Array(input.nulTerminatedUTF8))
let unterminatedData = Data(bytes: Array(input.utf8))
</code></pre>

Pass PHP variable to Javascript won't work : <p>I have two different pages for my site, lets call them page1 and page2. On the first page I have a HTML form of which handles some information. Then I have a php document to process that information into a .txt file. Then I have an image on my page2, this image I would like to change depending on a specific variable. This variable is set in the php script, where it checks if a certain value is right then it will set this specific variable to either 1 or 2. Then as said on page2 I have this image I would like to change depending on whether the php variable is 1 or 2. This I am trying to do by getting the php variable through javascript on page2 and then displaying it first to make sure I am getting the right values. But when doing this I just get "null" and pretty much nothing really happens. It loads the page but doesn't display anything. Keep in mind when I am saying pages etc it is because the page1 is one HTML document, page2 is another HTML document and then of course the php function is a separate php document. </p>

Custom domain for API Gateway returning 403 : <p>I am creating an api using API Gateway and Lambda. Using the url designated in the API Gateway Stage editor everything works fine; however, when I try and move to a custom domain I am running into some issues. </p>
<p>The first thing I tried was using a CNAME record in Route 53 straight from my domain onto the domain that I got from the API Gateway. That was returning some errors and I think it is the incorrect solution is that correct?</p>
<p>Next I tried the Custom Domain Names feature in API Gateway. My understanding is this will roll up a CloudFront distribution that I can then map onto from Route 53. When I created the custom domain and added a Domain Mapping it provides me with a url to what I assume is a CloudFront distribution. The link is returning a 403 response and no distribution has been made in CloudFront. What is a good way of debugging this problem?</p>

<p>Using AndroidStudio 3.0.1, I have a <code>DialogFragment</code> where I do this usual stuff:</p>
<pre><code> @Override
@NonNull
public Dialog onCreateDialog(Bundle savedInstanceState) {
AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
...
</code></pre>
<p>I have a lint warning moaning at me that <code>Argument 'getActivity()' might be null</code>. </p>
<p>I understand <em>why</em> <code>getActivity()</code> may be null, and I understand how the lint inspection knows this (from the <code>@Nullable</code> annotation). </p>
<p>My question is: It's all very well and good that <code>getActivity()</code> may be null, but practically how am I supposed to deal with this gracefully and tidily? <code>onCreateDialog</code> <em>must</em> return a <code>Dialog</code> (because of the superclass' <code>@Nullable</code> annotation) so I <em>must</em> have the Activity context to create it. </p>
<p>I could assume that <code>onCreateDialog</code> will never be called if the <code>DialogFragment</code> isn't attached to an Activity, but still - how do I address the untidy lint warning?</p>

unhashable type: 'list' while in function, but works well outside the function : <p>I am going to write a function instead of my old line by line code but looks like it doesn't work.</p>

How to separate presentation layer for Android from Windows in UWP app? : <p>I have rather larger enterprise class app in Silverlight. I want to convert it to a Windows 10 UWP app, which will be not too hard and I expect about 80% to be done without much problems.</p>
<p>However I see that a UWP app can target Android and Apple using Xamarin.</p>
<p>Can anyone share a practical guide - how to approach this?</p>
<p>I expect 50% of functionality be present in Xamarin "version" of the app - as there will be not enough screen on tablets and other features might be not available.</p>
<p>Whats the best architecture to reuse as much of the code as possible between Windows app and its mobile mini-me?</p>
<p><strong>How to organize VS projects and share libraries etc?</strong> </p>
<p><em>P.S. the data access in the Windows app will be WCF with EF and Oracle. I can easily mirror the WCF calls into REST service for the mobile app.</em></p>

Implementing a dynamic typed language with LLVM IR : <p>I'm trying to build a JIT compiler for a dynamic language using LLVM C API but I'm stuck at implementing dynamic types, for example in function definition, LLVM needs types for each argument but the type is unknown until runtime based on what the user passes, i googled this for a while but no any good resources about it anywhere, I also tried looking at Julia's source code to see how they did it, unfortunetely the code is big and complex and i have to eye jump everywhere to find such a small detail, from what i seen so far in it is they represent their types as an empty LLVM struct pointers and a func sig type that holds some extra data, but I'm very unsure of how that works or even if I'm explaining it right, any resources can be helpful, an example code is most appreciated, the example doesn't have to be in C API, C++ is also fine I'll convert it myself one way or the other.</p>

JPA concurrency issue "On release of batch it still contained JDBC statements" : <p>I have a a concurrency issue I tried to solve with a while loop that attempts to save an entity multiple times until it hits some max retry count. I'd like to avoid talking about whether or not there are other ways to solve this problem. I have other Stackoverflow posts about that. :) Long story short: there's a unique constraint on a column that is derived and includes a numeric portion that keeps incrementing to avoid collisions. In a loop, I:</p>
<ol>
<li>select max(some_value)</li>
<li>increment the result</li>
<li>attempt to save new object with this new result</li>
<li>explicitly flush the entity and, if that fails because of the unique index, I catch a DataAccessException.</li>
</ol>
<p>All of this seems to work except when the loop goes back to step 1 and tries to select, I get:</p>
<pre><code>17:20:46,111 INFO [org.hibernate.engine.jdbc.batch.internal.AbstractBatchImpl] (http-localhost/127.0.0.1:8080-3) HHH000010: On release of batch it still contained JDBC statements
17:20:46,111 INFO [my.Class] (http-localhost/127.0.0.1:8080-3) MESSAGE="Failed to save to database. Will retry (retry count now at: 9) Exception: could not execute statement; SQL [n/a]; constraint [SCHEMA_NAME.UNIQUE_CONSTRAINT_NAME]; nested exception is org.hibernate.exception.ConstraintViolationException: could not execute statement"
</code></pre>
<p>And a new Exception is caught. It seems like the first flush that causes the unique constraint violation and throws the <code>DataAccessException</code> doesn't clear the entity manager's batch. What's the appropriate way to deal with this? I'm using Spring with JPA and don't have direct access to the entity manager. I guess I could inject it if I need it but that's a painful solution to this problem.</p>

Prediction using Keras models : I trained a Keras model, however, I have difficulty in making it predict.
My input array is of the shape (400,2) and the output array is of the shape (400,1)
Now when I pass the argument array([1,2]) in the model.predict() function, I get the error:
ValueError: Error when checking input: expected dense_1_input to have shape (2,) but got array with shape (1,).
Which is nonsensical since shape(array([1,2])) = (2,) and hence the model.predict function should accept it as a valid input.
Can somebody tell me as to what is going on?
P.S.
It works well when I pass an array of (2,2) dimensions but the output is also a (2,1) array.

<p>To me both seems to do the same work, what is the actual difference. Is one deprecated? </p>

How to use a mask in excel vba? : I got as a required task to fix a date input in a vba form.
In the form, there is a textbox. I'm required to have for the user the date entered as
MM/DD/YYYY
My task is to use an input mask, this is what I'm required, not allowed to do something as validating date after or using a calendar.
So far I was able to use the 2 methods mentionned above (forcing the format after using `ISDATE`).
However, it's has now been made clear it HAS to be a mask so keys are filtered on entry, with the mask being visible when entering the date:
__/__/____
Is there a way to do it? I can only find tutorial for mask on access vba.

Replacing letters from input with a changing item from a list : In python, I'm trying to write a python script that replaces each letter with another letter from a 3 item long **list**. I am doing this for each letter of the alphabet, so use the `replace` method.
For example:
`list_a = "B,C,D" % `
`$ what is your message? > aaaa`
`$ This is your encrypted message: BCDB`
Thanks a lot!!!!

CSS: Position sticky js solution : [![question picture][1]][1]
[1]: https://i.stack.imgur.com/nv3vU.png
I have position sticky block that can be higher than window height and also can be less (depends on viewport). That means in some situations I cannot scroll to overflowed content. Is there a solution that allows to stick block from bottom if this block is bigger than window?

How to save a view in BigQuery - Standard SQL Dialect : <p>I am trying to save a view using BigQuery's WebUI, which was created in Standard SQL Dialect, but I am getting this error:</p>
<p><strong>Failed to save view. Bad table reference "myDataset.myTable"; table references in standard SQL views require explicit project IDs</strong></p>
<p>Why is this error showing up? How can I fix it? Should the "Table ID" field of the "Save view" dialog include the project id? Or does this error appear because of the query itself? Just in case, the query is running without any problems.</p>

Why will the CSS/Javscript and HTML only pass some properties, but not all? : I have downloaded source code for a hidden search bar, that when clicked, reveals a tex input bar.
I have copied this html into my homepage.html:
<div id="reserveButtonOuter"> <button id="reserveButton">Reserve a Table</button> </div>
<div id="sb-search" class="sb-search">
<form>
<input class="sb-search-input" placeholder="Enter your search term..." type="search" value="" name="search" id="search">
<input class="sb-search-submit" type="submit" value="">
<span class="sb-icon-search"></span>
</form>
</div>
this is connected to my HomePage.js file, in which I have the code below:
;( function( window ) {
function UISearch( el, options ) {
this.el = el;
this.inputEl = el.querySelector( 'form > input.sb-search-input' );
this._initEvents();
}
UISearch.prototype = {
_initEvents : function() {
var self = this,
initSearchFn = function( ev ) {
if( !classie.has( self.el, 'sb-search-open' ) ) { // open it
ev.preventDefault();
self.open();
}
else if( classie.has( self.el, 'sb-search-open' ) && /^\s*$/.test( self.inputEl.value ) ) { // close it
self.close();
}
}
this.el.addEventListener( 'click', initSearchFn );
this.inputEl.addEventListener( 'click', function( ev ) { ev.stopPropagation(); });
},
open : function() {
classie.add( this.el, 'sb-search-open' );
},
close : function() {
classie.remove( this.el, 'sb-search-open' );
}
}
This is only a small part of the code, as it is several hundred lines.
The .css file is linked to my page fine as it is working for my other elements. The search bar is rendering as nothing more than an orange square, which when clicked shows no errors on the console. Im not sure what that means for the Javascript?
Any advice would be great, thanks!

Docker named volumes vs DOC (data-only-containers) : <p>Up to recent version of Docker (v1.10), we were thought that we can use DOC: <em>data-only containers</em>. So I would create such DOC (based on e.g. busybox) and use <code>--volumes-from</code> to link it to my container. You can still read about this in <a href="https://docs.docker.com/engine/userguide/containers/dockervolumes/#creating-and-mounting-a-data-volume-container">Docker documentation</a>.</p>
<p>With new version of docker, it is said that instead of DOC we should use <code>named volumes</code>. Here is an example of <code>docker-compose.yml</code>:</p>
<pre><code>version: '2'
services:
elasticsearch:
image: elasticsearch:2.2.0
command: elasticsearch -Des.network.host=0.0.0.0
ports:
- "9201:9200"
volumes:
- "es-data:/usr/share/elasticsearch/data"
volumes:
es-data:
</code></pre>
<p>Here we created and use named volume <code>es-data</code>.</p>
<p>There is still not much documentation on this new feature. I am asking:</p>
<ul>
<li>Can we replace DOC with named containers? How long volume is persisted? What if I remove the container that is using it?</li>
<li>How can we e.g. backup now? Previously, I could <code>docker run --rm --volumes-from es-data ...</code> and then <code>tar</code> it.</li>
</ul>

Flutter - Render new Widgets on click : <p>The title basically says it all. A very nooby question... I have this basic code to create the initial state of my app :</p>
<pre><code>class MyApp extends StatelessWidget {
@override
Widget build(BuildContext context) {
return new MaterialApp(
title: 'Flutter Demo',
theme: new ThemeData(
primarySwatch: Colors.blue,
),
home: new MyHomePage(title: 'Some title'),
);
}
}
class MyHomePage extends StatefulWidget {
MyHomePage({Key key, this.title}) : super(key: key);
final String title;
@override
_MyHomePageState createState() => new _MyHomePageState();
}
class _MyHomePageState extends State<MyHomePage> {
@override
Widget build(BuildContext context) {
return new Scaffold(
appBar: new AppBar(title: new Text(config.title)),
body: new Column(
mainAxisAlignment: MainAxisAlignment.spaceEvenly,
children: [
new InputWidget(),
]
),
);
}
}
</code></pre>
<p>Now, how can I render a new Widget when the user clicks on a button? Let's say I want to instantiate another InputWidget.</p>
<p>thanks</p>

Keras: batch training for multiple large datasets : <p>this question regards the common problem of training on multiple large files in Keras which are jointly too large to fit on GPU memory.
I am using Keras 1.0.5 and I would like a solution that does not require 1.0.6.
One way to do this was described by fchollet
<a href="https://github.com/fchollet/keras/issues/107" rel="noreferrer">here</a> and
<a href="https://github.com/fchollet/keras/issues/68" rel="noreferrer">here</a>:</p>
<pre><code># Create generator that yields (current features X, current labels y)
def BatchGenerator(files):
for file in files:
current_data = pickle.load(open("file", "rb"))
X_train = current_data[:,:-1]
y_train = current_data[:,-1]
yield (X_train, y_train)
# train model on each dataset
for epoch in range(n_epochs):
for (X_train, y_train) in BatchGenerator(files):
model.fit(X_train, y_train, batch_size = 32, nb_epoch = 1)
</code></pre>
<p>However I fear that the state of the model is not saved, rather that the model is reinitialized not only between epochs but also between datasets. Each "Epoch 1/1" represents training on a different dataset below:</p>
<p>~~~~~ Epoch 0 ~~~~~~</p>
<p>Epoch 1/1
295806/295806 [==============================] - 13s - loss: 15.7517<br>
Epoch 1/1
407890/407890 [==============================] - 19s - loss: 15.8036<br>
Epoch 1/1
383188/383188 [==============================] - 19s - loss: 15.8130<br>
~~~~~ Epoch 1 ~~~~~~</p>
<p>Epoch 1/1
295806/295806 [==============================] - 14s - loss: 15.7517<br>
Epoch 1/1
407890/407890 [==============================] - 20s - loss: 15.8036<br>
Epoch 1/1
383188/383188 [==============================] - 15s - loss: 15.8130</p>
<p>I am aware that one can use model.fit_generator but as the method above was repeatedly suggested as a way of batch training I would like to know what I am doing wrong.</p>
<p>Thanks for your help,</p>

Symfony, how get current user (FOS) in entity, unused __construct()? : <p>I have an entity <code>Book</code>. Title of this <code>Book</code> is stored in different languages (the entity <code>Book</code> is associated with <code>BookTranslates</code> as <code>OneToMane</code>).</p>
<p>The entity <code>Book</code> is used as a form field in several places (like select). For this, I need to set <code>__toString ()</code> for the <code>Book</code> entity, which will return the title of the <code>Book</code> in the user's language.</p>
<p>I tried to get the user inside the entity by passing <code>TokenStorageInterface</code> in the <code>__construct ()</code> method of the <code>Book</code> class, but the doctrine never calls the <code>__construct ()</code> method in that case.</p>
<p>Brief statement of the problem:
<code>__toString ()</code> in entity must return a field of one of the related entities. Which specifically related entities - depends on the current user. How to implement it correctly?</p>
