Using Python Data Types Instead of 1-D Tensors In our training loop, we frequently aggregate values to calculate metrics, with the most common example being the update of the running loss during each iteration. However, if this is not done carefully in PyTorch, it can result in excessive me...
Python try-except blocks can be used to catch/respond to processes that raises more than one possible exception, with a single except clause.
Enclose in parentheses: 1 2 except(IDontLIkeYouException, YouAreBeingMeanException) as e: pass Separating the exception from the variable with a comma will still work in Python 2.6 and 2.7, but is now deprecated; now you should be using as....
