I am doing some volume rendering in yt and getting some errors when I try to grow the image size. I am trying to write a png image that is 1024 x 1024. I get the following errors:
image_array.py:229: RuntimeWarning: invalid value encountered in multiply
np.multiply(self[:, :, :3], 1.0/cmax, out[:, :, :3])
yt_array.py:764: RuntimeWarning: divide by zero encountered in divide
return YTArray(super(YTArray, self).__rdiv__(lo))
The largest image I can generate is about 800x 800. It is a nice image too I tell ya. Just wish I could do a bigger one to submit for publication.
Attached is the script I am using. Any help would be great.
