in file train.py, when i run python train.py -> Error : File "train.py", line 308, in
callbacks=callbacks_list)
line 308 : model.fit_generator(inputgenerator, epochs=100,
steps_per_epoch=TRAIN_NUM / int(BATCH_SIZE),
validation_data=testgenerator,
validation_steps=VAL_NUM / int(BATCH_SIZE),
use_multiprocessing=True,

I think it could be a version mismatch issue...
Anyway, i have updated the code for compatability.
I have confirmed that the code runs with python version: 3.6.9 and keras version: 2.4.3 in google colaboratory.
