Regionprops in skimage does not return intensity

Regionprops in skimage does not return intensity_mean

Regionprops in skimage does not return intensity_mean and returns an error. A minimal example is here:

from skimage import data, util
from skimage.measure import label, regionprops
img = util.img_as_ubyte(data.coins()) > 110
label_img = label(img, connectivity=img.ndim)
regions = regionprops(label_img)
for region in regions:
    print(region.area)

So the above example works, but the example below doesn't work:

from skimage import data, util
from skimage.measure import label, regionprops
img = util.img_as_ubyte(data.coins()) > 110
label_img = label(img, connectivity=img.ndim)
regions = regionprops(label_img)
for region in regions:
    print(region.intensity_mean)

Honestly, I don't know what to try!
