Exllama v2 Quantizations of starcoder2-3b

Using turboderp's ExLlamaV2 v0.0.19 for quantization.

The "main" branch only contains the measurement.json, download one of the other branches for the model (see below)

Each branch contains an individual bits per weight, with the main one containing only the meaurement.json for further conversions.

Conversion was done using the default calibration dataset.

Default arguments used except when the bits per weight is above 6.0, at that point the lm_head layer is quantized at 8 bits per weight instead of the default 6.

Original model: https://huggingface.co/bigcode/starcoder2-3b

8.0 bits per weight

6.5 bits per weight

5.0 bits per weight

4.25 bits per weight

3.5 bits per weight

Download instructions

With git:

git clone --single-branch --branch 6_5 https://huggingface.co/bartowski/starcoder2-3b-exl2

With huggingface hub (credit to TheBloke for instructions):

pip3 install huggingface-hub

To download the main (only useful if you only care about measurement.json) branch to a folder called starcoder2-3b-exl2:

mkdir starcoder2-3b-exl2
huggingface-cli download bartowski/starcoder2-3b-exl2 --local-dir starcoder2-3b-exl2 --local-dir-use-symlinks False

To download from a different branch, add the --revision parameter:

Linux:

mkdir starcoder2-3b-exl2-6_5
huggingface-cli download bartowski/starcoder2-3b-exl2 --revision 6_5 --local-dir starcoder2-3b-exl2-6_5 --local-dir-use-symlinks False

Windows (which apparently doesn't like _ in folders sometimes?):

mkdir starcoder2-3b-exl2-6.5
huggingface-cli download bartowski/starcoder2-3b-exl2 --revision 6_5 --local-dir starcoder2-3b-exl2-6.5 --local-dir-use-symlinks False
