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

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

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

Thank you!
