Hi,

In exercice 3 I have this result

dj_db at test w and b: -0.6

dj_dw at test w and b: [-44.83135361795273, -44.37384124957207]

When expected output

**dj_db at test w and b (non-zeros)** |
-0.5999999999991071 |

**dj_dw at test w and b (non-zeros):** |
[-44.8313536178737957, -44.37384124953978] |

Is it ok? the difference is very slight

After that my cost is 0.31 vs expected 0.3. Is there a bug? should I modify something or I can continue?

Best Regards

Eytan

Those seem close enough (to the limits of floating point numerical accuracy).

I recommend you continue.

Hi,

I submit the assignment but because of this slight difference I didn’t pass,

What I have to do?

Best Regards

Moreover, the test before that was ok

dj_db at initial w and b (zeros):-0.1 dj_dw at initial w and b (zeros):[-12.00921658929115, -11.262842205513591]

**Expected Output**:

**dj_db at initial w and b (zeros)** |
-0.1 |

**dj_dw at initial w and b (zeros):** |
[-12.00921658929115, -11.262842205513591] |
