TypeError: object of type 'NoneType' has no len() #130

I get the error TypeError: object of type 'NoneType' has no len() when running finetune.py using a text file for my dataset.

This error is raised because data.val_data is None. Looking into TrainTxt class, it notice it does not set self.val_data in TrainTxt.prepare_data.

Do not know how to fix this myself, hope to get some help!

If not using validation set, you should pass --val_set_size=0
