Hi,

I have been stuck on this issue for quite a long time. Any help on this issue would help me a lot.

I am facing one error after another in the function conv_forward. I tried looking into the errors others get and correcting my code. I was able to figure out resolving some of the previous errors but was unable to figure out where am I going wrong. No matter what I try, it keeps giving me the following error:

Error: Wrong output for variable in position 0.
2 Tests passed
1 Tests failed

AssertionError Traceback (most recent call last)

AssertionError: Not all tests were passed for conv_forward. Check your equations and avoid using global variables inside the function.

Please help me with this.

Best regards,

Finally resolved the issue. I tried many things in conv_forward function, but it turned out that there is a small detail in conv_single_step function which I missed out to check.

Hi @kavuriananthasai,

I’m glad you figured it out.

My apologise for not replying back in time, I had lost access to Discourse for a bit.

Cheers,
