7 years ago Hi @geek1111, The value of input_examples_size is zero and this caused the ZeroDivisionError. This is because there are no images in the folders for the five class labels i.e. forward, reverse, left, right and idle. Can you segregate the images into their respective folders and run the command?
Im having an issue when execute the command of "train.py".I have done every procedure accordingly . The error is given below . Please Help ASAP python version used : python 2.7
