PyTorch fundamental excersises

[zuglar]

Dear All,
I started to watch your videos and solve the first exercise. I have a ask about question number 7.
Why I can multiply two tensors without transpose?
For e.g. if I transpose tensor_A I always ge the error:
RuntimeError: The size of tensor a (2) must match the size of tensor b (3) at non-singleton dimension 1

I use PyCharm.
The python code has been attached.
Thank you in advance for your help
Best regards
Zoltan
