Hi, I’ve got an issue as below with conv_forward function. Any suggestion how to solve? Thanks!

Z’s mean =
0.5511277
Z[0,2,1] =
[-2.1779604 8.071713 -0.5772706 3.3628676 4.4811363 -2.8919847
10.992888 3.0317194]
cache_conv[0][1][2][3] =
[-1.1191154 1.9560789 -0.3264995 -1.34267579]
(2, 13, 15, 8)
Error: Wrong output for variable in position 0.
