Jointly use PyTorch and Pygmo #54

Closed jingyao-zhang closed 4 years ago

jingyao-zhang commented 4 years ago

When I try to use pytoch and pygmo jointly, the RuntimeError: Unable to cast Python instance to C++ type occours.

1) Is there a way to use pytorch in pygmo?

2) Should I use pagmo instead, with c++ of pytorch, because the error is the cast from python to c++?

@Ssicayoon it's not possible for us to help you without more specific info. Perhaps you can come over to the gitter channel, where it might be easier to have a discussion?

@bluescarni Thanks for your reply! I have found and fixed the problem, the wrong data type tensor for Pygmo functions.
