Hi, I"m not sure what i’m missing, I got dW2 and db2 right but dW1 is wrong, i followed the equations, but I’m missing something

{moderator edit - solution code removed}

I’m getting assertion wrong value for dW1,
dW1 = [[-0.00022433 0.00055688]
[-0.00501012 0.01245478]
[ 0.00023946 -0.00059417]
[ 0.00290866 -0.00721879]]
db1 = [[-0.00013131]
[-0.00293254]
[ 0.00014001]
[ 0.00170148]]
dW2 = [[ 0.00078841 0.01765429 -0.00084166 -0.01022527]]
db2 = [[-0.16655712]]

You have read the math formula for dZ1 incorrectly. Take another look: there are no references to dW2 in that formula, right?
