                Indeed, it works with the built version (branch: master commit: 0d5e4a2c6)… I’m not sure it is really a good news though. Asking an end-user to rebuild pytorch from source is, for our project, a bit too much. 
I hope next python package will not suffer the same problem… 
Anyway. Thank you for your k…
