Remote Machine Learning on M4 Mac Mini

🚧Setup🗄️Server☑️Ready

I have a TrueNAS server running Immich in the Apps section and want to use my M4 Mac for machine learning. So far, I've followed this discussion https://github.com/immich-app/immich/discussions/10454 and got to the point where everything works perfectly up until I actually try to run a job.

I did these commands on my Mac to set it up:

brew update
brew upgrade
softwareupdate --install-rosetta --agree-to-license
brew reinstall gcc gfortran scipy pyenv uv
git clone https://github.com/immich-app/immich
cd immich/machine-learning
pyenv install 3.11.6
pyenv global 3.11.6
uv sync --python 3.11 --extra cpu
source .venv/bin/activate
python -m immich_ml

brew update
brew upgrade
softwareupdate --install-rosetta --agree-to-license
brew reinstall gcc gfortran scipy pyenv uv
git clone https://github.com/immich-app/immich
cd immich/machine-learning
pyenv install 3.11.6
pyenv global 3.11.6
uv sync --python 3.11 --extra cpu
source .venv/bin/activate
python -m immich_ml

then did this on my Immich webUI
immich webui > profile picture > administration > settings > machine learning settings > URL > set http://<MAC MINI IP>:3003

but when i start a Smart Search job on the Immich webUI i repeatedly get this error on the mac:

basically a loop of errors where it crashes or something but then it gets restarted only to crash again.
I also attached my TrueNAS compose file and all the console outputs from my mac in a text file.
