Try running it python2. That worked for me.

epoch result: nan for ndcg

Greetings to the team! Your code is beautiful, but I'm lost in the implementation of it.

I have the last version of PyTorch: https://pytorch.org/get-started/locally/ & Python

  • Stable (1.8.1)
  • OS: Windows
  • Package: PiP
  • Computer Platform: CUDA 11.1
  • Python: 3.8.7

When I train the model I receive the outputs:

  • test_te.csv
  • test_tr.csv
  • validation_tr.csv
  • validation_te.csv
  • train
  • unique_sid
  • unique_uid (For k = 100 in utils.py)

image

If I change the utils.py in the return of ndcg function for: return DCG/IDCG to: return np.divide(DCG,IDCG, where=IDCG!=0) it solve it, but still giving 'low' values. The latter in comparison with other VAE-CF results.

Can you help me, please?

Congratulations. I reiterate, your code is beautiful in comparison to tensorflow-keras implementation.

Best regards, Mirko.
