TypeError: Cannot cast ufunc add output from dtype('float64') to dtype('uint8

I just installed binglide on a variant of Ubuntu, but I get the following error message when trying to open files. I have yet to install numba but from what I gathered from the instructions it was optional?

Alright, got it to at least load files by making the following changes. It looks like the problem is with numpy's latest versions where they've changed the way implicit casting works? I've no idea what if any side effects may result from the changes I've made, but it seems to be working at least..

mixers.py at line 18

colored[..., c] = colored[..., c] + (data * coefs[c])

projectors.py at line 38

data = np.pad(data, ((0, np.int32(nsize-size)), (0, 0)), 'constant')

Oh. Thanks for the report! I haven't tried binglide on the latest ubuntu myself. I don't have time right now, but I might look at it during the week-end. If you get it to work feel free to make a pull-request with the changes that seem to be working for you. I might use it as a base.
