Hello!
First of all, a humble Thank you to you for creating this repository and of course the python module :)

Here is an issue I am facing, the log of which is pasted:

As seen above in the log, the training has successfully started and just when it is about to unleash its powers, an error is thrown and the training stops.
Tensorflow version: 1.14.0
Pillow version: 5.4.1
aocr version: 0.7.6

ANY help or thoughts on this will be much, much appreciated.
Gratitude,
Sushanth

The reason why when it is loading, leading to this error.
