"stop iteration" trouble

[rominageysels]

Hi, I'm trying to run MMSplice using the google colab notebook online. For some reason, I wasn't able to download MMSplice from kipoi directly in my computer... maybe it was because I have Windows, not Linux OS. I got lots of errors I just couldn't deal with. Anyways, I tried to run this model online to assess my VCF and in this part:

predict_save(model, dl, output_csv, pathogenicity=True, splicing_efficiency=True)

I got this error:

StopIteration Traceback (most recent call last)
in ()
----> 1 predict_save(model, dl, output_csv, pathogenicity=True, splicing_efficiency=True)

1 frames
/usr/local/lib/python3.7/dist-packages/mmsplice/mmsplice.py in predict_save(model, dataloader, output_csv, batch_size, progress, pathogenicity, splicing_efficiency)

--> 274 return df_batch_writer(df_iter, output_csv)

---> 43 df = next(df_iter)
44 with open(output, 'w') as f:
45 df.to_csv(f, index=False)

StopIteration:

Obviously, I can't run the next lines because something is missing there. I think may be this is a bug, but i'm not sure (I'm not an expert in programming)
Would you advice me to try installing MMSplice in another computer with LinuxOS instead of running the google colab?
I will be very grateful if you can help me solve this issue, and if someone got the same error please let me know too.

Could you please double-check whether your VCF file is empty or the format is incorrect?

I checked, the VCF file is not empty. I created it using Data Slicer from Ensembl(GRCh37), then downloaded as a compressed file.
