Cat and Dog Image Classifier

I am currently on probabilities in the cat dog image and all the modules before have been debugged without any error.
But I don’t, know what’s wrong with the function.

my code so far is :
probabilities = model.predict(test_data_gen)[:,0]
plotImages(test_data_gen[0][0], probabilities)

That’s not a log to go on, especially with this challenge. You’ll need to post a link to your colab notebook (and the error message would be helpful too) so that others can see and run your code in order for people to have a chance of helping you. There is a lot that can go wrong in the machine learning challenges.
