ValueError: no standard masks exist for given bitdepth with alpha
this is an example code throwing this issue
different other codes throws the same with draw()
i had the same issue on ipython notebook and on console output
CODE (for ipython notebook)
from SimpleCV import Image, Color, Display
disp = Display(displaytype='notebook')
# load an image from imgur
img = Image('http://i.imgur.com/lfAeZ4n.png')
# use a keypoint detector to find areas of interest
feats = img.findKeypoints()
# draw the list of keypoints
feats.draw(color=Color.RED)
# show the resulting image.
img.show()
# apply the stuff we found to the image.
output = img.applyLayers()
# save the results.
output.save(disp)

Hello
I've been using docker image to test simplecv
I fall on this issue
