TypeError: not a sequence

When using PyTorch to build a deep learning model, I think the above error is the most troublesome. The biggest problem is that this error report basically doesn’t tell what kind of error happened. It’s up to the user to look at his own data format.

Today when I use PyTorch to build a model, I got an error message:

ValueError: expected sequence of length 300 at dim 1 (got 3)
