In the test of the exercise lstm_forward I was getting a error in the line "print("a[4][3][6] = “, a_tmp[4][3][6])” saying that it was out of bounds. But when I changed the “6” to 3 worked.
I noted another possible error. My output is different than the expected output, but I passed in the text and in the assignment with 100/100
I suspect there is an error in your code that the grader did not detect. Neither the grader nor the notebook unit tests are comprehensive.
