W4_Ex-4_Tests failing

Course Q&A Deep Learning Specialization Neural Networks and Deep Learning

Hello @tfu, I have exactly the same behavior as your image|690x437

But replacing layers_dim with the three dimensions as an array(list) did not change anything for me. I bump into the “2 Tests passed, 1 Tests failed” with “Error: Wrong output for variables W1,b1,W2,b2 and 0”…

My problem output (as text, seems identical to image|690x437 ) is:

Cost after iteration 1: 0.6564026188409187
Cost after first iteration: 0.6950464961800915
Cost after iteration 1: 0.7239781229671559
Cost after iteration 1: 0.7239781229671559

Error: Wrong output for variable W1.
Error: Wrong output for variable b1.
Error: Wrong output for variable W2.

Error: Wrong output for variable 0.

Note: the “cost” @tfu and I obtained on “first” iteration indicated on this post: https://community.deeplearning.ai/t/week-4-exercise-4-not-passing-both-tests/11880

(hence iteration 0) seems the same as other people indicated on post https://community.deeplearning.ai/t/course-1-week-4-programming-assignment-2/5587

although @michael.brent seems to have obtained
a different iteration 0 cost 0.6930497356599888 on Post#6 May 23, 1:03 PM

although also @tfu may have obtained
a different iteration 0 cost ??? on Post#3 Jun 4, 5:31 PM
