after reviewing all existing discussions on this topic, I have ran out of ideas about what I might be doing wrong. at some point my cost after iteration 1 was actually close to 0.69 as expected but outputs were still wrong; I have since lost track of why I don’t get the same error messages.
I made sure all previous cells were ran.
sigmoid comes before relu.
what might the error be?
Cost after iteration 1: 0.8396276891856396
Cost after first iteration: 1.293099325833286
Cost after iteration 1: nan
