There's always a mismatch between Expected size for first two dimensions of batch2 tensor

like execution of the following code gives a runtime error

RuntimeError: Expected size for first two dimensions of batch2 tensor to be: [40, 9] but got: [40, 1].

@Ron993 What is the rest of your code? I just tried the snippet you sent and it seemed to work just fine. Can you send a minimal representation that demonstrates your issue?
It may be possibly be versioning issues as well. Make sure everything is up to date
