For this issue the api was giving the following error in the terminal everytime we import a model, even if ollama is not installed.

The app is trying to look for ollama models even if you don't have Ollama installed when you click on Import Models in the Model Zoo.

Failed to locate Ollama models library:
[Errno 2] No such file or directory: 'Ollama models directory'

The try catch probably doesn't account for this case or maybe it does but still gives this error

OK no wait I take back my approval. I don't have OLLAMA_MODELS set in my environment and I have Ollama installed! I think we need a different thing to check for?

I'm not sure of the best way. Maybe check if shutil.which("ollama") isn't None?

Or do the thing Deep said and catch the specific error? I'm not sure which is better but this one doesn't work for me.

Sure I will delete it
