C2W3_Lab_01_Model_Evaluation_and_Selection - Question on NN Training MSE results

Course Q&A Machine Learning Specialization Advanced Learning Algorithms

Hi, I implemented this lab on my own machine and I never get the same Training MSE results whenever I run my code for NN model selection part. How come in the lab we always get the same training MSE values every time?

From lab:
RESULTS:
Model 1: Training MSE: 73.44, CV MSE: 113.87
Model 2: Training MSE: 73.40, CV MSE: 112.28
Model 3: Training MSE: 44.56, CV MSE: 88.51

From my code:
RESULTS:
Model 1: Training MSE: 406.19, CV MSE: 551.78
Model 2: Training MSE: 406.19, CV MSE: 551.78
Model 3: Training MSE: 75.39, CV MSE: 98.90

Thank you

Your results for MSE are quite different than the lab results.

Are you certain your local copy is correct, and that your code uses all of the same settings?
