# Run Ollama with IPEX-LLM on Intel GPU
|
|
|
|
[ollama/ollama](https://github.com/ollama/ollama) is popular framework designed to build and run language models on a local machine; you can now use the C++ interface of [`ipex-llm`](https://github.com/intel-analytics/ipex-llm) as an accelerated backend for `ollama` running on Intel **GPU** *(e.g., local PC with iGPU, discrete GPU such as Arc, Flex and Max)*.
|
|
|
|
See the demo of running LLaMA2-7B on Intel Arc GPU below.

|
## Quickstart
|
|
|
|
### 1. Install IPEX-LLM for Ollama
|
|
|
|
IPEX-LLM's support for `ollama` now is available for Linux system and Windows system.
|
|
|
|
Visit [Run llama.cpp with IPEX-LLM on Intel GPU Guide](./llama_cpp_quickstart.md), and follow the instructions in section [Prerequisites](./llama_cpp_quickstart.md#0-prerequisites) to setup and section [Install IPEX-LLM cpp](./llama_cpp_quickstart.md#1-install-ipex-llm-for-llamacpp) to install the IPEX-LLM with Ollama binaries.
|
|
|
|
**After the installation, you should have created a conda environment, named `llm-cpp` for instance, for running `ollama` commands with IPEX-LLM.**
|
|
|
|
### 2. Initialize Ollama
|
|
|
|
Activate the `llm-cpp` conda environment and initialize Ollama by executing the commands below. A symbolic link to `ollama` will appear in your current directory.
|
|
|
|
- For **Linux users**:
|
|
|
|
```bash
|
|
conda activate llm-cpp
|
|
init-ollama
|
|
```
|
|
|
|
- For **Windows users**:
|
|
|
|
Please run the following command with **administrator privilege in Miniforge Prompt**.
|
|
|
|
```cmd
|
|
conda activate llm-cpp
|
|
init-ollama.bat
|
|
```
|
|
|
|
> [!NOTE]
|
|
> If you have installed higher version `ipex-llm[cpp]` and want to upgrade your ollama binary file, don't forget to remove old binary files first and initialize again with `init-ollama` or `init-ollama.bat`.
|
|
|
|
**Now you can use this executable file by standard ollama's usage.**
|
|
|
|
### 3. Run Ollama Serve
|
|
|
|
You may launch the Ollama service as below:
|
|
|
|
- For **Linux users**:
|
|
|
|
```bash
|
|
export OLLAMA_NUM_GPU=999
|
|
export no_proxy=localhost,127.0.0.1
|
|
export ZES_ENABLE_SYSMAN=1
|
|
source /opt/intel/oneapi/setvars.sh
|
|
export SYCL_CACHE_PERSISTENT=1
|
|
export SYCL_PI_LEVEL_ZERO_USE_IMMEDIATE_COMMANDLISTS=1
|
|
# [optional] if you want to run on single GPU, use below command to limit GPU may improve performance
|
|
export ONEAPI_DEVICE_SELECTOR=level_zero:0
|
|
|
|
./ollama serve
|
|
```
|
|
|
|
- For **Windows users**:
|
|
|
|
Please run the following command in Miniforge Prompt.
|
|
|
|
```cmd
|
|
set OLLAMA_NUM_GPU=999
|
|
set no_proxy=localhost,127.0.0.1
|
|
set ZES_ENABLE_SYSMAN=1
|
|
set SYCL_CACHE_PERSISTENT=1
|
|
set SYCL_PI_LEVEL_ZERO_USE_IMMEDIATE_COMMANDLISTS=1
|
|
|
|
ollama serve
|
|
```
|
|
|
|
> [!NOTE]
|
|
> Please set environment variable `OLLAMA_NUM_GPU` to `999` to make sure all layers of your model are running on Intel GPU, otherwise, some layers may run on CPU.
|
|
|
|
> [!NOTE]
|
|
> To allow the service to accept connections from all IP addresses, use `OLLAMA_HOST=0.0.0.0 ./ollama serve` instead of just `./ollama serve`.
|
|
|
|
> [!TIP]
|
|
> When your machine has multi GPUs and you want to run on one of them, you need to set `ONEAPI_DEVICE_SELECTOR=level_zero:[gpu_id]`, here `[gpu_id]` varies based on your requirement. For more details, you can refer to [this section](../Overview/KeyFeatures/multi_gpus_selection.md#2-oneapi-device-selector).
|
|
|
|
The console will display messages similar to the following:
|
|
|
|
<a href="https://llm-assets.readthedocs.io/en/latest/_images/ollama_serve.png" target="_blank">
|
|
<img src="https://llm-assets.readthedocs.io/en/latest/_images/ollama_serve.png" width=100%; />
|
|
</a>
|
|
|
|
|
|
### 4. Pull Model
|
|
Keep the Ollama service on and open another terminal and run `./ollama pull <model_name>` in Linux (`ollama.exe pull <model_name>` in Windows) to automatically pull a model. e.g. `dolphin-phi:latest`:
|
|
|
|
<a href="https://llm-assets.readthedocs.io/en/latest/_images/ollama_pull.png" target="_blank">
|
|
<img src="https://llm-assets.readthedocs.io/en/latest/_images/ollama_pull.png" width=100%; />
|
|
</a>
|
|
|
|
|
|
### 5. Using Ollama
|
|
|
|
#### Using Curl
|
|
|
|
Using `curl` is the easiest way to verify the API service and model. Execute the following commands in a terminal. **Replace the <model_name> with your pulled
|
|
model**, e.g. `dolphin-phi`.
|
|
|
|
- For **Linux users**:
|
|
|
|
```bash
|
|
curl http://localhost:11434/api/generate -d '
|
|
{
|
|
"model": "<model_name>",
|
|
"prompt": "Why is the sky blue?",
|
|
"stream": false
|
|
}'
|
|
```
|
|
|
|
- For **Windows users**:
|
|
|
|
Please run the following command in Miniforge Prompt.
|
|
|
|
```cmd
|
|
curl http://localhost:11434/api/generate -d "
|
|
{
|
|
\"model\": \"<model_name>\",
|
|
\"prompt\": \"Why is the sky blue?\",
|
|
\"stream\": false
|
|
}"
|
|
```
|
|
|
|
#### Using Ollama Run GGUF models
|
|
|
|
Ollama supports importing GGUF models in the Modelfile, for example, suppose you have downloaded a `mistral-7b-instruct-v0.1.Q4_K_M.gguf` from [Mistral-7B-Instruct-v0.1-GGUF](https://huggingface.co/TheBloke/Mistral-7B-Instruct-v0.1-GGUF/tree/main), then you can create a file named `Modelfile`:
|
|
|
|
```bash
|
|
FROM ./mistral-7b-instruct-v0.1.Q4_K_M.gguf
|
|
TEMPLATE [INST] {{ .Prompt }} [/INST]
|
|
PARAMETER num_predict 64
|
|
```
|
|
|
|
Then you can create the model in Ollama by `ollama create example -f Modelfile` and use `ollama run` to run the model directly on console.
|
|
|
|
- For **Linux users**:
|
|
|
|
```bash
|
|
export no_proxy=localhost,127.0.0.1
|
|
./ollama create example -f Modelfile
|
|
./ollama run example
|
|
```
|
|
|
|
- For **Windows users**:
|
|
|
|
Please run the following command in Miniforge Prompt.
|
|
|
|
```cmd
|
|
set no_proxy=localhost,127.0.0.1
|
|
ollama create example -f Modelfile
|
|
ollama run example
|
|
```
|
|
|
|
An example process of interacting with model with `ollama run example` looks like the following:

|
|
</a>
|
|
|
|
### Troubleshooting
|
|
#### Unable to run the initialization script
|
|
If you are unable to run `init-ollama.bat`, please make sure you have installed `ipex-llm[cpp]` in your conda environment. If you have installed it, please check if you have activated the correct conda environment. Also, if you are using Windows, please make sure you have run the script with administrator privilege in prompt terminal.
|
|
|
|
#### Why model is always loaded again after several minutes
|
|
Ollama will unload model from gpu memory in every 5 minutes as default. For latest version of ollama, you could set `OLLAMA_KEEP_ALIVE=-1` to keep the model loaded in memory. Reference issue: https://github.com/intel-analytics/ipex-llm/issues/11608
|
|
|
|
#### `exit status 0xc0000135` error when executing `ollama serve`
|
|
When executing `ollama serve`, if you meet `llama runner process has terminated: exit status 0xc0000135` on Windows or you meet `ollama_llama_server: error while loading shared libraries: libmkl_core.so.2: cannot open shared object file` on Linux, this is most likely caused by the lack of sycl dependency. Please check:
|
|
|
|
1. if you have installed conda and if you are in the right conda environment which has pip installed oneapi dependencies on Windows
|
|
2. if you have executed `source /opt/intel/oneapi/setvars.sh` on Linux
|
|
|
|
#### Program hang during initial model loading stage
|
|
When launching `ollama serve` for the first time on Windows, it may get stuck during the model loading phase. If you notice that the program is hanging for a long time during the first run, you can manually input a space or other characters on the server side to ensure the program is running.
|
|
|
|
#### How to distinguish the community version of Ollama from the ipex-llm version of Ollama
|
|
In the server log of community version of Ollama, you may see `source=payload_common.go:139 msg="Dynamic LLM libraries [rocm_v60000 cpu_avx2 cuda_v11 cpu cpu_avx]"`.
|
|
But in the server log of ipex-llm version of Ollama, you should only see `source=payload.go:44 msg="Dynamic LLM libraries [cpu cpu_avx cpu_avx2]"`.
|
|
|
|
#### Ollama hang when multiple different questions is asked or context is long
|
|
If you find ollama hang when multiple different questions is asked or context is long, and you see `update_slots : failed to free spaces in the KV cache` in the server log, this could be because that sometimes the LLM context is larger than the default `n_ctx` value, you may increase the `n_ctx` and try it again. |
