However, the product of the shape's components (2,2,3) still has to be equal to the number of elements in the original tensor ( 12). Note that PyTorch has another function that you may see called view() that does the same thing as the reshape() function, but don't let these ...
# In this way, we are basically saying: the weight is 13 and the bias is 2. targets = 13*x + 2 + noise # Check the shape of the targets just in case. It should be n x m, where n is the number of samples # and m is the number of output variables, so 1000 x 1. ...
