also just saw this

2024-04-10 03:06:05.775820413 _interpreter_wrapper.CreateWrapperFromFile(
2024-04-10 03:06:05.775886950 ValueError: Model provided has model identifier 'l ve', should be 'TFL3'

what is TFL3?

[ht2k05]

potentially something in the model is corrupt?

[NickM-27]

Try deleting the model and then restarting frigate.

[ht2k05]

its a custom model though as part of frigate plus, i cant delete it....

if i delete the custom model code TPU works fine and frigate works fine...

[NickM-27]

Sure you can delete it. Just open /config/model_cache and delete everything in there

[ht2k05]

You are a genius, deleted the model in /config/model_cache and using the same custom code TPU....worked perfectly....something in the cache was causing it to crash i supposed...THANK YOU!!!

[ht2k05]

ok and then re request a new model?
