I can’t seem to find anything wrong with the code, so I dont understand the error.

I also got the same problem

Hi noel9981,

This message indicates that you are using an operator instead of an Add() layer while constructing ResNet50. Have a look at the layers and see if you can locate where you do this. Good luck!

Hello Sir,

Thank you for the prompt reply.
Based on stated from the code cell, I’ve edited my code to include Add(), but the weirdest thing is, when I run the code and test it, the output I get, is the input_shape and a text box that lets me enter values, which makes no sense.

####input##############
model = ResNet50(input_shape = (64, 64, 3), classes = 6)
print(model.summary())
#####output##############
(64, 64, 3) (a textbox)

Is it possible for me to show you my code personally?

Hi noel9981,

Yes, that’s ok. You can send me your code using a direct message. I will then have a look.
