Saving training files

[Ellie]

Getting error:

FileNotFoundError: [Errno 2] No such file or directory:

File "\Python\Python35\lib\site-packages\numpy\lib\npyio.py", line 492, in save
    fid = open(file, "wb")

When attempting to save to >training_data-2 or 3 etc.
should it not be creating the files?

I was being super dumb and had left the file name as /filename rather than just the filename.
