Helly yt-crowd.

 

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.

 

Thanks,

Dave Semeraro
