It’d be nice if the error message for torch.cat was more specific. For example, when I run the following
import torch a = torch.FloatTensor(1) b = torch.DoubleTensor(1) c = torch.cat((a, b)) # Error since a and b are different types
I get the following error
Traceback (most recent call last): File "foo.py", line 5, in <module> c = torch.cat((a, b)) TypeError: cat received an invalid combination of arguments - got (tuple), but expected one of: * (sequence[torch.FloatTensor] seq) didn't match because some of the arguments have invalid types: (tuple) * (sequence[torch.FloatTensor] seq, int dim)
It’d be nice if it said something like, “got mixed types but expected…” I spent a while double checking my inputs before I realized the types were different.
Looks like this confusion was also the cause for this post.
