SOLAR-10.7B

In this directory, you will find examples on how you could use BigDL-LLM optimize_model API to accelerate SOLAR-10.7B models. For illustration purposes, we utilize the upstage/SOLAR-10.7B-Instruct-v1.0 as a reference SOLAR-10.7B model.

Requirements

To run these examples with BigDL-LLM, we have some recommended requirements for your machine, please refer to here for more information.

Example: Predict Tokens using generate() API

In the example generate.py, we show a basic use case for a SOLAR-10.7B model to predict the next N tokens using generate() API, with BigDL-LLM INT4 optimizations.

1. Install

We suggest using conda to manage the Python environment. For more information about conda installation, please refer to here.

After installing conda, create a Python environment for BigDL-LLM:

conda create -n llm python=3.9 # recommend to use Python 3.9
conda activate llm

pip install --pre --upgrade bigdl-llm[all] # install the latest bigdl-llm nightly build with 'all' option
pip install transformers==4.35.2 # required by SOLAR-10.7B

2. Run

After setting up the Python environment, you could run the example by following steps.

2.1 Client

On client Windows machines, it is recommended to run directly with full utilization of all cores:

python ./generate.py --repo-id-or-model-path REPO_ID_OR_MODEL_PATH --prompt PROMPT --n-predict N_PREDICT

More information about arguments can be found in Arguments Info section. The expected output can be found in Sample Output section.

2.2 Server

For optimal performance on server, it is recommended to set several environment variables (refer to here for more information), and run the example with all the physical cores of a single socket.

E.g. on Linux,

# set BigDL-LLM env variables
source bigdl-llm-init

# e.g. for a server with 48 cores per socket
export OMP_NUM_THREADS=48
numactl -C 0-47 -m 0 python ./generate.py --prompt 'What is AI?'

More information about arguments can be found in Arguments Info section. The expected output can be found in Sample Output section.

2.3 Arguments Info

In the example, several arguments can be passed to satisfy your requirements:

• --repo-id-or-model-path: str, argument defining the huggingface repo id for the SOLAR-10.7B model to be downloaded, or the path to the huggingface checkpoint folder. It is default to be 'upstage/SOLAR-10.7B-Instruct-v1.0'.
• --prompt: str, argument defining the prompt to be inferred (with integrated prompt format for chat). It is default to be 'What is AI?'.
• --n-predict: int, argument defining the max number of tokens to predict. It is default to be 32.
