Hi ! I have a nice ndarray image viewer built on OpenGL - one annoyance though is that is crashes if the array contains any NaN, or inf, ...
So, I found N.nan_to_num - but OpenGL (read: video cards) supports only single precision float (N.float32)
So I get this:
N.nan_to_num([N.inf])
[ 1.79769313e+308]
N.nan_to_num([N.inf]).astype(N.float32)
[ inf]
Could nan_to_num() get an optional dtype argument ?
Thanks, Sebastian Haase
OK - sorry for the noise... this is how to do it:
N.nan_to_num( N.array([N.nan,N.inf,-N.inf],N.float32) ) [ 0.00000000e+00 3.40282347e+38 -3.40282347e+38]
In the meantime I noticed that there is a N.asarray_chkfinite() function but no equivalent for N.asanyarray() ! Should N.asanyarray_chkfinite() be added !? -Sebastian
