There was a problem grading your submission. Details: Incompatible shapes: [361,10] vs. [361] [Op:SquaredDifference]

what can be the reason and how i can solve this?

The issue is resolved. Basically i changed the learning rate too much from 1e-6 to 1e-5 and that gives good results in terms of mse which was not acceptable by the autograder, later i changed the learning rate to 4e-6 which worked. thanks anyway

Incompatible shapes has nothing to do with learning rate. You’ve changed the right parameter that fixes the problem, unknowingly.

Could anyone give more hints?

I also got the same issue “There was a problem grading your submission. Details: Incompatible shapes: [361,10] vs. [361] [Op:SquaredDifference]”

Does this help?
