# Starcoder
|
|
In this directory, you will find examples on how you could run Starcoder BF16 inference with self-speculative decoding using IPEX-LLM on [Intel CPUs](../README.md). For illustration purposes,we utilize the [bigcode/starcoder](https://huggingface.co/bigcode/starcoder) and [bigcode/tiny_starcoder_py](https://huggingface.co/bigcode/tiny_starcoder_py) as reference Starcoder models.
|
|
|
|
## 0. Requirements
|
|
To run these examples with IPEX-LLM on Intel CPUs, we have some recommended requirements for your machine, please refer to [here](../README.md#recommended-requirements) for more information.
|
|
|
|
## Example: Predict Tokens using `generate()` API
|
|
In the example [speculative.py](./speculative.py), we show a basic use case for a Starcoder model to predict the next N tokens using `generate()` API, with IPEX-LLM speculative decoding optimizations on Intel CPUs.
|
|
### 1. Install
|
|
We suggest using conda to manage environment:
|
|
```bash
|
|
conda create -n llm python=3.11
|
|
conda activate llm
|
|
pip install --pre --upgrade ipex-llm[all]
|
|
pip install intel_extension_for_pytorch==2.1.0
|
|
pip install transformers==4.31.0
|
|
```
|
|
### 2. Configures high-performing processor environment variables
|
|
```bash
|
|
source ipex-llm-init -t
|
|
export OMP_NUM_THREADS=48 # you can change 48 here to #cores of one processor socket
|
|
```
|
|
### 3. Run
|
|
|
|
We recommend to use `numactl` to bind the program to a specified processor socket:
|
|
|
|
```bash
|
|
numactl -C 0-47 -m 0 python ./speculative.py --repo-id-or-model-path REPO_ID_OR_MODEL_PATH --prompt PROMPT --n-predict N_PREDICT
|
|
```
|
|
|
|
For example, 0-47 means bind the python program to core list 0-47 for a 48-core socket.
|
|
|
|
Arguments info:
|
|
|
|
- `--repo-id-or-model-path REPO_ID_OR_MODEL_PATH`: argument defining the huggingface repo id for the Starcoder model (e.g. `bigcode/starcoder` and `bigcode/tiny_starcoder_py`) to be downloaded, or the path to the huggingface checkpoint folder. It is default to be `bigcode/starcoder`.
|
|
- `--prompt PROMPT`: argument defining the prompt to be infered (with integrated prompt format for chat). A default prompt is provided.
|
|
- `--n-predict N_PREDICT`: argument defining the max number of tokens to predict. It is default to be `128`.
