Overall, I recommend using the old CUDA branch. It is included by default in the one-click-installer for this web UI.
### Installation using precompiled wheels
### Installation
Start by cloning GPTQ-for-LLaMa into your `text-generation-webui/repositories` folder:
```
mkdir repositories
cd repositories
git clone https://github.com/oobabooga/GPTQ-for-LLaMa.git -b cuda
```
If you want to you to use the up-to-date CUDA or triton branches instead of the old CUDA branch, use these commands:
```
git clone https://github.com/qwopqwop200/GPTQ-for-LLaMa.git -b cuda
```
```
git clone https://github.com/qwopqwop200/GPTQ-for-LLaMa.git -b triton
```
Next you need to install the CUDA extensions. You can do that either by installing the precompiled wheels, or by compiling the wheels yourself.
### Precompiled wheels

The command above takes some 10 minutes to run and shows no progress bar or updates along the way.

You are going to need to have a C++ compiler installed. On Linux, `sudo apt install build-essential` or equivalent is enough.
#### Step 1: install GPTQ-for-LLaMa
If you're using an older version of CUDA toolkit (e.g. 11.7) but the latest version of `gcc` and `g++` (12.0+), you should downgrade with: `conda install -c conda-forge gxx==11.3.0`. Kernel compilation will fail otherwise.
Clone the GPTQ-for-LLaMa repository into the `text-generation-webui/repositories` subfolder and install it:
#### Step 2: compile the CUDA extensions
```
mkdir repositories
cd repositories
git clone https://github.com/oobabooga/GPTQ-for-LLaMa.git -b cuda
cd GPTQ-for-LLaMa
cd repositories/GPTQ-for-LLaMa
python setup_cuda.py install
```

#### Step 2: get the pre-converted weights
### Pre-converted weights
* Converted without `group-size` (better for the 7b model): https://github.com/oobabooga/text-generation-webui/pull/530#issuecomment-1483891617
* Converted with `group-size` (better from 13b upwards): https://github.com/oobabooga/text-generation-webui/pull/530#issuecomment-1483941105
⚠️ The tokenizer files in the sources above may be outdated. Make sure to obtain the universal LLaMA tokenizer as described [here](https://github.com/oobabooga/text-generation-webui/blob/main/docs/LLaMA-model.md#option-1-pre-converted-weights).
