## Install Prerequisites
|
|
|
|
### Update NPU Driver
|
|
|
|
> [!IMPORTANT]
|
|
> If you have NPU driver version lower than `32.0.100.3104`, it is highly recommended to update your NPU driver to the latest.
|
|
|
|
To update driver for Intel NPU:
|
|
|
|
1. Download the latest NPU driver
|
|
|
|
- Visit the [official Intel NPU driver page for Windows](https://www.intel.com/content/www/us/en/download/794734/intel-npu-driver-windows.html) and download the latest driver zip file.
|
|
- Extract the driver zip file
|
|
|
|
2. Install the driver
|
|
|
|
- Open **Device Manager** and locate **Neural processors** -> **Intel(R) AI Boost** in the device list
|
|
- Right-click on **Intel(R) AI Boost** and select **Update driver**
|
|
- Choose **Browse my computer for drivers**, navigate to the folder where you extracted the driver zip file, and select **Next**
|
|
- Wait for the installation finished
|
|
|
|
A system reboot is necessary to apply the changes after the installation is complete.
|
|
|
|
### (Optional) Install Visual Studio 2022
|
|
|
|
> [!NOTE]
|
|
> To use IPEX-LLM **C++ API** on Intel NPU, you are required to install Visual Studio 2022 on your system. If you plan to use the **Python API**, skip this step.
|
|
|
|
Install [Visual Studio 2022](https://visualstudio.microsoft.com/downloads/) Community Edition and select "Desktop development with C++" workload:

|
|
</div>
|
|
|
|
### Setup Python Environment
|
|
|
|
Visit [Miniforge installation page](https://conda-forge.org/download/), download the **Miniforge installer for Windows**, and follow the instructions to complete the installation.
|
|
|
|

|
|
<img src="https://llm-assets.readthedocs.io/en/latest/_images/quickstart_windows_gpu_miniforge_download.png" width=80%/>
|
|
</div>
|
|
|
|
After installation, open the **Miniforge Prompt**, create a new python environment `llm-npu`:
|
|
```cmd
|
|
conda create -n llm-npu python=3.11
|
|
```
|
|
Activate the newly created environment `llm-npu`:
|
|
```cmd
|
|
conda activate llm-npu
|
|
```
|
|
|
|
> [!TIP]
|
|
> `ipex-llm` for NPU supports Python 3.10 and 3.11.
|
|
|
|
### (Optional) Install CMake
|
|
|
|
> [!NOTE]
|
|
> Cmake installation is for IPEX-LLM **C++ API** on Intel NPU. If you plan to use the **Python API**, skip this step.
|
|
|
|
With the `llm-npu` environment active, install CMake:
|
|
|
|
```cmd
|

```
|
|
|
|
## Install `ipex-llm` with NPU Support
|
|
|
|
With the `llm-npu` environment active, use `pip` to install `ipex-llm` for NPU:
|
|
|
|
```cmd
|
|
conda activate llm-npu
|
|
|
|
pip install --pre --upgrade ipex-llm[npu]
|
|
```
|
|
|
|
## Runtime Configurations

### Save & Load Low-Bit Models
|
|
|
|
IPEX-LLM also provides Python API for saving/loading models with low-bit optimizations on Intel NPU, to avoid repeated loading & optimizing of the original models. Refer to the [Save-Load example](../../../python/llm/example/NPU/HF-Transformers-AutoModels/Save-Load) for usage in details.
|
|
|
|
## C++ API
|
|
|
|
IPEX-LLM also provides C++ API for running Hugging Face `transformers` models.

## Accuracy Tuning
|
|
|
|
IPEX-LLM provides several optimization methods for enhancing the accuracy of model outputs on Intel NPU. You can select and combine these techniques to achieve better outputs based on your specific use case.
|
|
|
|
### 1. `IPEX_LLM_NPU_QUANTIZATION_OPT` Env
|
|
|
|
You could set environment variable `IPEX_LLM_NPU_QUANTIZATION_OPT=1` before loading & optimizing the model with `from_pretrained` function from `ipex_llm.transformers.npu_model` Auto Model class to further enhance model accuracy of low-bit models.
|
|
|
|
### 2. Low-Bit Optimizations
|
|
|
|
IPEX-LLM on Intel NPU currently supports `sym_int4`/`asym_int4`/`sym_int8` low-bit optimizations. You could adjust the low-bit value to tune the accuracy.
|
|
|
|
For example, you could try to set `load_in_low_bit='asym_int4'` instead of `load_in_low_bit='sym_int4'` when loading & optimizing the model with `from_pretrained` function from `ipex_llm.transformers.npu_model` Auto Model class, to switch from `sym_int4` low-bit optimizations to `asym_int4`.
|
|
|
|
### 3. Mixed Precision
|
|
|
|
When loading & optimizing the model with `from_pretrained` function of `ipex_llm.transformers.npu_model` Auto Model class, you could try to set parameter `mixed_precision=True` to enable mixed precision optimization when encountering output problems.
|
|
|
|
### 4. Group Size
|
|
|
|
IPEX-LLM low-bit optimizations support both channel-wise and group-wise quantization on Intel NPU. When loading & optimizing the model with `from_pretrained` function of Auto Model class from `ipex_llm.transformers.npu_model`, parameter `quantization_group_size` will control whether to use channel-wise or group-wise quantization.
|
|
|
|
If setting `quantization_group_size=0`, IPEX-LLM will use channel-wise quantization. If setting `quantization_group_size=128`, IPEX-LLM will use group-wise quantization with group size 128.
|
|
|
|
You could try to use group-wise quantization for better outputs. |
