Libraries

How to use CohereLabs/c4ai-command-r-plus with Transformers:

# Use a pipeline as a high-level helper
from transformers import pipeline

pipe = pipeline("text-generation", model="CohereLabs/c4ai-command-r-plus")
messages = [
    {"role": "user", "content": "Who are you?"},
]
pipe(messages)

# Load model directly
from transformers import AutoTokenizer, AutoModelForCausalLM

tokenizer = AutoTokenizer.from_pretrained("CohereLabs/c4ai-command-r-plus")
model = AutoModelForCausalLM.from_pretrained("CohereLabs/c4ai-command-r-plus")
messages = [
    {"role": "user", "content": "Who are you?"},
]
inputs = tokenizer.apply_chat_template(
	messages,
	add_generation_prompt=True,
	tokenize=True,
	return_dict=True,
	return_tensors="pt",
).to(model.device)

outputs = model.generate(**inputs, max_new_tokens=40)
print(tokenizer.decode(outputs[0][inputs["input_ids"].shape[-1]:]))

What's up? Can't get any response from this model. All others seem to be working. No "model is overloaded" message. It runs on a Space though, but I prefer HuggingChat. I tried different browsers and different prompt. Never any response.

Same here. This happened just over a month ago, too. It was down for one day then came back. Hopefully this is the same thing this time and it'll be back later. I'm not worrying yet!

It seems to be following a new change to the repository, @ahmetustun @Rocketknight1

HuggingChat is no longer working with the model.

Hey @iNeverLearnedHowToRead @MarkKra @mafistov , sorry about the inconvenience. But yes it looks like the model is down on HF chat.
I'll check with HF staff and Ahmet and we'll try to get the model back online asap. Will post here once the issue is resolved.
