Thank you 
Hello @Prajwal_Surendra,
We read the error message from bottom up. If we look at this part,
we see that the error was triggered when np.zeros was called. And if we look up the documentation for np.zeros, we will find that the whole underlined thing is supposed to be a tuple of integer which echos the error message: it expected integers but it was given None. We can further verify this hypothesis by experimenting it ourselves:
Look. The same error message can be reproduced.
From these two lines of the error messages:
it seems that your train_generator has used some image preprocessing steps, and it’s likely to have something to do with that. To check, you might need to first identify which preprocessing functions from the Keras package were used; then inspect each input argument to each of those functions and see if anything was wrong. This is all I can share with you based on the error traceback. However, it is going to be your assignment to fix the error, so I will stop here.
Lastly, I think you have posted this question in the wrong category because there is no such assignment in the MLS. Please share the name of the course so that I can help you move it back to the right category.
Cheers,
Raymond
Hi ,In your data set contain objects, so convert into numeric using onehotencoder or imputer methods
In this picture top cell please remove tenserflow and type tf
from tf.keras.optimizer import RMSprop
Hello @manohar_kota
On my computer, from tf.keras.optimizers ... won’t work
However, from tensorflow.keras.optimizers ... can:
Raymond
while importing we have to use full name like tensorflow
sorry if say anything wrong ,i am just biginner of this course
