Error in Evaluation Step

[tengguna]

I am trying to do the TWSVM with OVO. I saw the document and followed the instructions. I got stuck in this part:
'acc, std, full_report = eval_func(h_params)'

When I tried to run the code, I got this error:
'TypeError: Expected sequence or array-like, got <class 'NoneType'>'

I already make sure that X and y are not empty. Can you please help me?

Hi,
Sorry for the late reply. I'm super busy nowadays.
Could you please post here the full stack trace? so that I can help you further.
Also, you can add a minimal example that helps to reproduce the error.
