# Running Ollama on NVIDIA Jetson Devices
With some minor configuration, Ollama runs well on [NVIDIA Jetson Devices](https://www.nvidia.com/en-us/autonomous-machines/embedded-systems/). The following has been tested on [JetPack 5.1.2](https://developer.nvidia.com/embedded/jetpack).
Ollama runs well on [NVIDIA Jetson Devices](https://www.nvidia.com/en-us/autonomous-machines/embedded-systems/) and should run out of the box with the standard installation instructions.
NVIDIA Jetson devices are Linux-based embedded AI computers that are purpose-built for AI applications.
Jetsons have an integrated GPU that is wired directly to the memory controller of the machine. For this reason, the `nvidia-smi` command is unrecognized, and Ollama proceeds to operate in "CPU only"
mode. This can be verified by using a monitoring tool like jtop.
In order to address this, we simply pass the path to the Jetson's pre-installed CUDA libraries into `ollama serve` (while in a tmux session). We then hardcode the num_gpu parameters into a cloned
version of our target model.
Prerequisites:
- curl
- tmux
Here are the steps:
The following has been tested on [JetPack 5.1.2](https://developer.nvidia.com/embedded/jetpack), but should also work on JetPack 6.0.
- Install Ollama via standard Linux command (ignore the 404 error): `curl https://ollama.com/install.sh | sh`
- Stop the Ollama service: `sudo systemctl stop ollama`
- Start Ollama serve in a tmux session called ollama_jetson and reference the CUDA libraries path: `tmux has-session -t ollama_jetson 2>/dev/null || tmux new-session -d -s ollama_jetson
'LD_LIBRARY_PATH=/usr/local/cuda/lib64 ollama serve'`
- Pull the model you want to use (e.g. mistral): `ollama pull mistral`
- Create a new Modelfile specifically for enabling GPU support on the Jetson: `touch ModelfileMistralJetson`
- In the ModelfileMistralJetson file, specify the FROM model and the num_gpu PARAMETER as shown below:
```
FROM mistral
PARAMETER num_gpu 999
```
- Create a new model from your Modelfile: `ollama create mistral-jetson -f ./ModelfileMistralJetson`
- Run the new model: `ollama run mistral-jetson`
If you run a monitoring tool like jtop you should now see that Ollama is using the Jetson's integrated GPU.
- Start an interactive session: `ollama run mistral`
And that's it!
# Running Ollama in Docker
When running GPU accelerated applications in Docker, it is highly recommended to use [dusty-nv jetson-containers repo](https://github.com/dusty-nv/jetson-containers).
