Plot overlay gives NaN error with uint8 images about antspy

[rodriguez-facundo]

btw, I read about this line to overcome a weird NaN error from matplotlib with overlay in ants/viz/plot.pt but did not worked.

warnings.simplefilter('ignore')

thanks - I will take a look. if you have a pull request ( a suggested fix to code ) that would be great.

Hi, is ov_arr[np.abs(ov_arr) == 0] = np.nan there to skip computation over positions with value NaN? (like using np.nanmean). NaN only exists in float type. My quick fix (🤣) would be:

if overlat.dtype not in ['uint8', 'uint32']:
    ov_arr[np.abs(ov_arr) == 0] = np.nan

implemented your suggested fix here 5ed4d11

please reopen if you have thought of some other approach
