Frigate+ model not downloaded

[zoechi]

I run Frigate on NixOS and just tried to configure a Plus model, but I get an error shortly after Frigate (as systemd service) is started.

There is an empty directory var/cache/frigate/model_cache

What am I missing?

[NickM-27]

something is broken with the configuration because the path is being set but the model is not there which means the model is being downloaded somewhere else. the way you are running frigate isn't an officially supported configuration so I am not aware of where that might be. running find / -name '373d2276296b9a115937117a0eb568e7' find figure it out

[zoechi]

Should there be some entry in the logs about the failing model download, because I couldn't find anything. There was only the above error about the file not existing.

[NickM-27]

it will specifically try to install to /config/model_cache, perhaps it fails due to permission issues or something.

[zoechi]

Is there a way to configure where it should look for the model_cache.
The Systemd unit config configures CONFIG_FILE and HOME environment variables

Environment="CONFIG_FILE=/nix/store/aw1zgpbf058j5ldcd8zc0div7sg48ga0-frigate.yml"
Environment="HOME=/var/lib/frigate"

Perhaps I need to set SystemD RootDirectory to /var/lib/frigate or /var/cache/frigate.

Frigate on NixOS seems quite popular, but I couldn't find anything about configuring the Frigate+ model yet.

[NickM-27]

@blakeblackshear might have some input on how best to handle this

[blakeblackshear]

There are several files stored in the config directory, so I would suggest figuring out how to get a /config directory working properly.
