Access violation after importing colour (from colour-science) #661
Description
test:
import numpy as np
from wand.resource import genesis as wand_genesis
from wand.image import Image
# as a workaround, call wand_genesis() before importing other packages
# this also runs successfully if we don't import colour at all.
#wand_genesis()
import colour # from https://github.com/colour-science/colour
with Image.from_array(np.linspace(0, 1, 256*256).reshape([256, 256])) as img:
img.save(filename=f'test.exr')
print("saved")This will raise an exception from the save() call.
r = library.MagickWriteImage(self.wand, filename)
