Hello @nadtriana and @paulinpaloalto ,
Thank you for your advices.
I double-checked all the stages of the code in Exercise 3 - ResNet50 for misspellings, typos, the order of arguments, alignment with instructions, etc.
Everything was correct.
I also reviewed the answers for similar issues in the community one more time and found a thread that helped me identify the root of the problem Course 4 week 2 exercise 3 ResNet50 - error in test
Despite the notification that “All tests passed,” the issue was caused by an error in the previous exercise (Exercise 2 - convolutional_block). I didn’t follow the correct order mentioned in the code comments for the Final Step
of Exercise 2.
Thanks again for your help.
