Diarization does not work

[olsn]

First of all: thank you for the nice project! It works really well - except when, i try to activate diarization.

The docker-log then shows: torchvision is not available - cannot save figures

The response of the rest-call is:

{
  "detail": "'NoneType' object has no attribute 'eval'"
}

I have not yet tried to install torchvision, but maybe that's all that's neede?
