Download the Langchain-Chatchat with IPEX-LLM integrations from this link. Unzip the content into a directory, e.g.,C:\Users\arda\Downloads\Langchain-Chatchat-ipex-llm
.
Visit the Install IPEX-LLM on Windows with Intel GPU Guide, and follow Install Prerequisites to update GPU driver (optional), and install Conda.
Open Miniforge Prompt, and run the following commands to create a new python environment:
conda create -n ipex-llm-langchain-chatchat python=3.11 libuv
conda activate ipex-llm-langchain-chatchat
pip install --pre --upgrade ipex-llm[xpu] --extra-index-url https://pytorch-extension.intel.com/release-whl/stable/xpu/us/
pip install --pre --upgrade torchaudio==2.1.0a0 --extra-index-url https://pytorch-extension.intel.com/release-whl/stable/xpu/us/
Note
You can also use --extra-index-url https://pytorch-extension.intel.com/release-whl/stable/xpu/cn/
.
Switch to the root directory of Langchain-Chatchat you've downloaded (refer to the download section), and install the dependencies with the commands below. Note: In the example commands we assume the root directory is C:\Users\arda\Downloads\Langchain-Chatchat-ipex-llm
. Remember to change it to your own path.
cd C:\Users\arda\Downloads\Langchain-Chatchat-ipex-llm
pip install -r requirements_ipex_llm.txt
pip install -r requirements_api_ipex_llm.txt
pip install -r requirements_webui.txt
- In root directory of Langchain-Chatchat, run the following command to create a config:
python copy_config_example.py
- Edit the file
configs\model_config.py
, changeMODEL_ROOT_PATH
to the absolute path of the parent directory where all the downloaded models (LLMs, embedding models, ranking models, etc.) are stored.
Download the models and place them in the directory MODEL_ROOT_PATH
(refer to details in Configuration section).
Currently, we support only the LLM/embedding models specified in the table below. You can download these models using the link provided in the table. Note: Ensure the model folder name matches the last segment of the model ID following "/", for example, for THUDM/chatglm3-6b
, the model folder name should be chatglm3-6b
.
Model | Category | download link |
---|---|---|
THUDM/chatglm3-6b |
Chinese LLM | HF or ModelScope |
meta-llama/Llama-2-7b-chat-hf |
English LLM | HF |
BAAI/bge-large-zh-v1.5 |
Chinese Embedding | HF |
BAAI/bge-large-en-v1.5 |
English Embedding | HF |
When you run this applcation on Intel GPU for the first time, it is highly recommended to do a one-time warmup (for GPU kernels compilation).
In Miniforge Prompt, under the root directory of Langchain-Chatchat, with conda environment activated, run the following commands:
conda activate ipex-llm-langchain-chatchat
set SYCL_CACHE_PERSISTENT=1
set BIGDL_LLM_XMX_DISABLED=1
python warmup.py
Note
The warmup may take several minutes. You just have to run it one-time on after installation.
Open Miniforge Prompt and run the following commands:
conda activate ipex-llm-langchain-chatchat
set SYCL_CACHE_PERSISTENT=1
set BIGDL_LLM_XMX_DISABLED=1
set BIGDL_IMPORT_IPEX=0
set no_proxy=localhost,127.0.0.1
python startup.py -a
