Variable referenced before assignment causing training issues

As per Martha's testing, classification is currently working on new Calvo (found in the develop branch) however training is not. The method createGenerator in training_engine_sae.py attempts to use a variable a line before it is ever initialized.

Line 80 may just simply need to be moved below Line 83, but I am unable to test this myself locally until after my flight and would rather not blindly change things. If anyone else wants to give it a shot in the meanwhile feel free!

Calvo_classifier/training_engine_sae.py

Line 77 in eae1d50

    
           def createGenerator(grs, gts, idx_label, patch_height, patch_width, batch_size):

This may not be the full extent of the issue, but it's a start

Closed and moved to #41 as it has details about further issues in the function.
