The part related is as below:
tensor([[-0.0106,  0.8890,  0.0561,  0.9582, -0.0059,  0.7418, -0.0096,  0.9744]])
this is the x in my first loop above.
Sorry if it is hard to read because I can only post one image.
I am wondering why I am getting this error message and what it means. If I change the shape from[1,8] to [8,1] then I get a message like dimension mismatch [8,1]  [8,5]
How can I fix this problem?
