Week 2: logistic_regression_model is never set because of failure in model()

Course Q&A Deep Learning Specialization Neural Networks and Deep Learning

The logistic_regression_model variable is never set because of an error … the error happens during the calculation of the last Cost calculated.

ValueError: operands could not be broadcast together with shapes (1,50) (1,209)

I changed the num_iterations variable to 2100 and 1999 … and the calculation always fails with the same error.

All previous code passed the in-built tests.
Any suggestions?

Thank you!

And looking at the Cost results … the Costs are decreasing with each iteration and those values seem right to me …

EDIT2:
Well … turns out I had my Y_train and Y_test swapped …
Things are working now!
