### 4. Accelerate with BIGDL_OPT_IPEX
To accelerate speculative decoding on CPU, you can install our validated version of [IPEX 2.3.0+git004cd72d](https://github.com/intel/intel-extension-for-pytorch/tree/004cd72db60e87bb0712d42e3120bac9854bd77e) by following steps: (Other versions of IPEX may have some conflicts and can not accelerate speculative decoding correctly.)
#### 4.1 Download IPEX installation script
```bash
# Depend on Conda and GCC 12.3
wget https://raw.githubusercontent.com/intel/intel-extension-for-pytorch/004cd72db60e87bb0712d42e3120bac9854bd77e/scripts/compile_bundle.sh
```
#### 4.2 Activate your conda environment
```bash
conda activate <your_conda_env>
```
#### 4.3 Set VER_IPEX in compile_bundle.sh to 004cd72db60e87bb0712d42e3120bac9854bd77e
```bash
sed -i 's/VER_IPEX=main/VER_IPEX=004cd72db60e87bb0712d42e3120bac9854bd77e/g' "compile_bundle.sh"
```
#### 4.4 Install IPEX and other dependencies
```bash
# Install IPEX 2.3.0+git004cd72d
bash compile_bundle.sh
# Update transformers
pip install transformers==4.36.2
