Hi,
I have encountered this error and I am struggling with this. I do not know how to overcome this. I have not changed any original code. I would be grateful if anyone can help me with this.
Best,
Armin
I believe your compute_cost_reg function is returning the cost value as an array, rather than as a scalar.
Dear TMosh,
Thanks for your kind reply. I have solved my problem.
Best regard,
Armin
