Predict and Save as error handling #6

Closed agitter closed 5 years ago

agitter commented 5 years ago

I trained a model on the telomere example data and proceeded to Step 3: Test and Predict. I clicked the Predict and Save as button but then cancelled, which crashed the GUI.

Here is the stack trace:

Traceback (most recent call last):

I found the bug and it is an easy fix. A condition for checking the file path was missing. I will push the change to the repo after the workshop.
