Running main_density_multidim.py produces error

[davidwynter]

I get this error when I run main_density_multidim.py

/home/david/PycharmProjects/Wavelets/functions.py:301: RuntimeWarning: invalid value encountered in true_divide
density = density_z[:, index] / sum(density_z[:, index])

I have almost finished converting WaveletMultiDim.py to use numba for a big speed improvement. Happy to share this when it is complete.

It is not clear to me why you np.flip the test and train values?

Thanks for your feedback.

Will check what is causing the error and the flip issue this week end and let you know.

Look forward to learn more about numba !

Cheers

I can't reproduce the error (I believe you added some lines in functions.py ?). But in the division comes from dividing by zero (so maybe a simple if zero should do the trick).

Hopes this help
