A quesion in test_deploy example #295

Closed KexinFeng closed 1 year ago

KexinFeng commented 1 year ago

There is a line of code that seems problematic. https://github.com/pytorch/multipy/blob/cef6cac074fc2d72e7b73e88bf39478d859c6386/multipy/runtime/test_deploy.cpp#L461-L462

In this test of autograd, why is result = w.grad commented while keeping another hardcoding result? I have tried to uncomment the former and comment the latter. Then AutoGrad test failed. Is there an issue there?

I found the cause. It's due to the randomness several lines above.
