pynvrtc: 'Program' object has no attribute '_program'

[Jiankai-Sun]

Firstly, thank you for your great work!

Following your README.md, I installed the s2cnn successfully.

However, when I run example/equivariance_error.py, error occurs:

(cuda9) jiankai@fibonacci:~/data/Applications/s2cnn/examples/equivariance_error$ python main.py 
compute 0.pkl.gz... save 0.pkl.gz... done
Traceback (most recent call last):

It seems that this problem is caused by pynvrtc, do you have any suggestions?

Thank you!

Thank you for reporting this issue.

Fixed in facdf5c
Apparently, the library pynvrtc changed, now they require str instead of bytes for the code and the filename.

Here is the commit NVIDIA/pynvrtc@6417a28
