Description
The example code for slic results in a DeprecationWarning.
Way to reproduce
from skimage.segmentation import slic
from skimage.data import astronaut
img = astronaut()
segments = slic(img, n_segments=100, compactness=10)Output:
Traceback (most recent call last):
File "<input>", line 4, in <module>
File "C:\Users\ntjes\miniconda3\envs\py38\lib\site-packages\skimage\segmentation\slic_superpixels.py", line 206, in slic
image = img_as_float(image)
File "C:\Users\ntjes\miniconda3\envs\py38\lib\site-packages\skimage\util\dtype.py", line 452, in img_as_float
return _convert(image, np.floating, force_copy)
File "C:\Users\ntjes\miniconda3\envs\py38\lib\site-packages\skimage\util\dtype.py", line 226, in _convert
dtypeobj_out = np.dtype(dtype)
DeprecationWarning: Converting `np.inexact` or `np.floating` to a dtype is deprecated. The current result is `float64` which is not strictly correct.
