EOFError: Ran out of input

Hello, I am having trouble running the training for the model. Each issue I have had so far, I have been able to figure out myself, but this is the first that I truly didn't understand.

Traceback (most recent call last):

EOFError: Ran out of input

From what I could find, the error could be coming from a file that is being overwritten, but I could not find any evidence of that happening in the various library files. Any assistance would be greatly appreciated. Thank you very much!
