[Lab 1 Part 1.3] Solution throws AssertionError on Apple M1?

[adrianhak]

Running the solution notebook for section 1.3 returns an AssertionError (pasted below)
I'm running macOS 11.5.1 on the M1 chip, using tensorflow-macos 2.5.0

Have anyone got this working on the M1 chip?

If this is MIT lab, I had the same problem because was referencing b from the context instead of self.b , but please keep this post for future generations

[rlamba89]

I am using the same machine, also referring self.b and getting the same error. Is there any way to rectify this issue?
