I have encountered a error in model training and the error is _main__:79: RuntimeWarning: overflow encountered in multiply __main__:80: RuntimeWarning: overflow encountered in multiply __main__:80: RuntimeWarning: invalid value encountered in subtract Iteration: 10 ; error = nan Iteration: 20 ; error = nan about matrix-factorization-in-python HOT 2 CLOSED

The problem has been solved as i reduced the alpha value and increased the number of epochs for gradient descent to converge.

Thanks

main:79: RuntimeWarning: overflow encountered in multiply
main:80: RuntimeWarning: overflow encountered in multiply
main:80: RuntimeWarning: invalid value encountered in subtract
Iteration: 10 ; error = nan
Iteration: 20 ; error = nan

and my training_process shows all nan's
