Original GitHub issue: https://github.com/ollama/ollama/issues/2277

Originally assigned to: @dhiltgen on GitHub.

I have installed ollama (v0.1.22) and ROCm (v5.7.1) to Arch Linux via the following commands

pacman -S ollama rocm-hip-sdk rocm-opencl-sdk clblast
systemctl daemon-reload
systemctl enable ollama.service
systemctl start ollama.service

and then run

ollama run mistral

Checking htop and nvtop, I see that only CPU is being used.

Ollama log in journalctl -u ollama shows the following:

Searching for GPU management library libnvidia-ml.so
Discovered GPU libraries: []
Searching for GPU management library librocm_smi64.so
Discovered GPU libraries: [/opt/rocm/lib/librocm_smi64.so.5.0]
Radeon GPU detected
ROCm integrated GPU detected - ROCR_VISIBLE_DEVICES=1

I believe the ROCR_VISIBLE_DEVICES parameter should be set to 0.

My system info is below:

How can I tell ollama to use the external GPU?

Please run the server with OLLAMA_DEBUG=1 and attach the logs of the early startup so we can see why it's selecting the wrong GPU.

As a workaround until this is fixed, if you set ROCR_VISIBLE_DEVICES=0 explicitly before starting the server, it should respect your setting.
