# Chatglm3-32k
|
|
In this directory, you will find examples on how you could apply IPEX-LLM INT4/FP8 optimizations on Chatglm3-32K models on [Intel GPUs](../../../README.md). For illustration purposes, we utilize the [THUDM/chatglm3-6b-32k](https://huggingface.co/THUDM/chatglm3-6b-32k) as reference Chatglm3-32K models.
|
|
|
|
## 0. Requirements
|
|
To run these examples with IPEX-LLM on Intel GPUs, we have some recommended requirements for your machine, please refer to [here](../../../README.md#requirements) for more information.
|
|
|
|
## Example: Predict Tokens using `generate()` API
|
|
In the example [generate.py](./generate.py), we show a basic use case for a Chatglm3 model to predict the next N tokens using `generate()` API, with IPEX-LLM INT4/FP8 optimizations on Intel GPUs.
|
|
### 1. Install
|
|
#### 1.1 Installation on Linux
|
|
We suggest using conda to manage environment:
|
|
```bash
|
|
conda create -n llm python=3.11
|
|
conda activate llm
|
|
# below command will install intel_extension_for_pytorch==2.1.10+xpu as default
|
|
pip install --pre --upgrade ipex-llm[xpu] --extra-index-url https://pytorch-extension.intel.com/release-whl/stable/xpu/us/
|
|
```
|
|
|
|
#### 1.2 Installation on Windows
|
|
We suggest using conda to manage environment:
|
|
```bash
|
|
conda create -n llm python=3.11 libuv
|
|
conda activate llm
|
|
|
|
# below command will install intel_extension_for_pytorch==2.1.10+xpu as default
|
|
pip install --pre --upgrade ipex-llm[xpu] --extra-index-url https://pytorch-extension.intel.com/release-whl/stable/xpu/us/
|
|
```
|
|
|
|
### 2. Configures OneAPI environment variables for Linux
|
|
|
|
> [!NOTE]
|
|
> Skip this step if you are running on Windows.
|
|
|
|
This is a required step on Linux for APT or offline installed oneAPI. Skip this step for PIP-installed oneAPI.
|
|
|
|
```bash
|
|
source /opt/intel/oneapi/setvars.sh
|
|
```
|
|
|
|
### 3. Runtime Configurations
|
|
For optimal performance, it is recommended to set several environment variables. Please check out the suggestions based on your device.

### 4. Running examples
|
|
#### 4.1 Using simple prompt
|
|
```
|
|
python ./generate.py --repo-id-or-model-path REPO_ID_OR_MODEL_PATH --prompt PROMPT --n-predict N_PREDICT --low-bit LOW_BIT
|
|
```
|
|
|
|
Arguments info:
|
|
- `--repo-id-or-model-path REPO_ID_OR_MODEL_PATH`: argument defining the huggingface repo id for the Chatglm3 model (e.g. `THUDM/chatglm3-6b-32k`) to be downloaded, or the path to the huggingface checkpoint folder. It is default to be `'THUDM/chatglm3-6b-32k'`.
|
|
- `--prompt PROMPT`: argument defining the prompt to be infered (with integrated prompt format for chat). It is default to be `'What is AI?'`.
|
|
- `--n-predict N_PREDICT`: argument defining the max number of tokens to predict. It is default to be `32`.
|
|
- `--low-bit LOW_BIT`: argument defining which low bit optimization to use. Options are sym_int4 or fp8. It is default to be `sym_int4`.
|
|
|
|
#### 4.2 Using long context input prompt
|
|
You can set the `prompt` argument to be a `.txt` file path containing the long context prompt text. An example command using the 8k input size prompt we provide is given below:
|
|
```
|
|
python ./generate.py --repo-id-or-model-path togethercomputer/chatglm3-6b-32k --prompt 8k.txt
|
|
```
|
|
> Note: If you need to run longer input or use less memory, please set `IPEX_LLM_LOW_MEM=1`, which will enable memory optimization and may slightly affect the latency performance.
