NameError: name 'layers' is not defined

PLEASE HELP!

Please can someone help me

I am no expert in neural networks but Python is right - there is no layers defined thus NameError. Shouldn’t you provide imported library name (keras.layers like in row #11 with data)?

not related to your question, but what do you think this line do

#CHECKING
train_images.shape,'/',train_labels.shape,'/',test_images.shape,'/',test_labels.shape

I mean, there is comment CHECKING, but...

I have been trying to solve this problem for 3 hours now. I did everything I knew, Searched whole youtube and Stackoverflow and have tried your suggestions as well but nothing seems to work.

why did you have layers in your code? what it is suppose to be? how do you write code you don't know why you have certain code?

---

did you try as suggested by @perfingo to replace layers with keras.layers?

Here are the docs to Tensorflow/keras/layers for conv2d
https://www.tensorflow.org/api_docs/pyth...ers/Conv2D

Examples are given, but in your case I suspect that where you have layers, change to tf.keras.layers and you will be ok.
This works. Cute car.

Thank you for all your answers. My problem has solved
