Capstone Text Recognition: CTC Loss implementation doubt

Hello,
I’m currently working on the Text Recognition part of the Capstone project. I’ve implemented a CRNN as explained by the professor with a CTC loss. For some reason, my loss is not decreasing and just oscillating at one point. Here’s the link to my notebook, any help would be appreciated.
