Ah, it's tensors.py, not tensor.py. I was searching the whole git history for tensor.py and couldn't find it. We removed tensors.py in our latest sympy, because it didn't work, exactly as you observed. > hacked. I don't see a way to attach a file in posting.

You may use it as a start, or you may base your code on top of the relativity.py.
