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

I'm trying to reproduce QRNN in the project and launch the command from readme example:

Does anybody know how to fix this issue?

I executed those two commands before the python -u main.py .... command, seems to solve the issue pip install cupy pynvrtc git+https://github.com/salesforce/pytorch-qrnn pip install pynvrtc==8.0
