When fine tuning pretrained segmentation model using pyannote.audio==3.1.1 on well-defined and registered custom finance dataset, it shows the following error message 'PicklingError: Can't pickle <class 'pyannote.database.registry.Finance'>: attribute lookup Finance on pyannote.database.registry failed'

Similar Issue for pyannote.audio 2.0
pyannote/pyannote-database#65
Stating that fix has been released in pyannote.database 4.0.3
For pyannote.audio 3.0 or above, the corresponding pyannote.database version should be above 5.0.1.

**Issue if upgrading to pyannote.audio==3.3.1
If upgrading pyannote.audio to the latest version (3.3.1), it shows the following error message. If using --user option to upgrade pyannote.audio by following the error message's instruction, the system's CUDA support will be broken. So, there might be a package limitation (or other reasons) which prevents us fine tuning segmentation model as part of fine tuning pyannote v3 model, instead, we can only fine tune hyper-parameter like clustering threshold, currently.

(vtt_pyannote_tune_v3) C:\Users\fcdfaz>pip install --upgrade pyannote.audio==3.3.1
ERROR: Could not install packages due to an OSError: [WinError 5] Access is denied: 'C:\Users\fcdfaz\AppData\Local\anaconda3\envs\vtt_pyannote_tune_v3\Library\bin\tbbmalloc.dll'
Consider using the --user option or check the permissions.

Is this a bug for pyannote.audio=3.1.1? How should I fix the PicklingError issue?

In addition, I cannot re-run the below tutorial successfully using pyannote.audio==3.1.1

Training on Windows is not supported.

Dear Hervé BREDIN,

Thank you very much for the quick reply.

May I check with you which systems the package would support? Do you have a webpage listing all the system requirements for different versions of the package?

Is pyannote.audio==3.1.1 supported on linux virtualbox (VMWare Workstation Player with Ubuntu) running on a GPU windows desktop?

Thanks a lot!

[ZhouFang928]

Dear Hervé BREDIN,

In addition, may I check with you whether the pyannote.ai commercial product has Windows support version, which can do both scoring and fine tuning on Windows system?

Thanks a lot!

[hbredin]

Unfortunately, I have no easy way to check whether any of these would work in a Virtualbox.
Maybe someone who did that already in pyannote user base can chime in?
