HI, I’m having a hard time fixing this error. I didn’t find a solution of other forums, but I noticed that this is not a stand alone problem.
The error states:

"
NotFoundError: Graph execution error:
[…]
Node: ‘sequential/conv2d/Conv2D’
No algorithm worked! Error messages:
[[{{node sequential/conv2d/Conv2D}}]] [Op:__inference_train_function_1098]
"

The images in this assignment have 3 color channels. You’ve specified the input shape to contain 1 color channel and hence the issue.
