Hi Georges,

I believe this is because you are using a tagged version of skimage (probably even the most recent, 0.10.1), but looking at the dev documentation, which reflects a recent move of Canny from filter to feature:
https://github.com/scikit-image/scikit-image/pull/1113

Which tutorials are you finding?

Anyway, your options are:

* Carry on using filter for now, know that this is the expected behaviour
* Download the latest `master` branch from github and install that, and use the new feature syntax for Canny.

Hope this helps!

Juan.

Hi everyone,

So the problem is that canny is not working under feature while i see all the tutorials online using the feature module
if i look at the directory, it s just not there

>>> print dir(skimage.feature)
['BRIEF', 'CENSURE', 'ORB', '__all__', '__builtins__', '__doc__', '__file__', '__name__', '__package__', '__path__', '_daisy', '_hessian_det_appx', '_hog', '_texture', 'blob', 'blob_dog', 'blob_doh', 'blob_log', 'brief', 'brief_cy', 'censure', 'censure_cy', 'corner', 'corner_cy', 'corner_fast', 'corner_foerstner', 'corner_harris', 'corner_kitchen_rosenfeld', 'corner_moravec', 'corner_orientations', 'corner_peaks', 'corner_shi_tomasi', 'corner_subpix', 'daisy', 'greycomatrix', 'greycoprops', 'hessian_matrix', 'hessian_matrix_det', 'hessian_matrix_eigvals', 'hog', 'local_binary_pattern', 'match', 'match_descriptors', 'match_template', 'orb', 'orb_cy', 'peak', 'peak_local_max', 'plot_matches', 'structure_tensor', 'structure_tensor_eigvals', 'template', 'texture', 'util']

looked up a bit on the web this issue, found that it s in feature, proven by :  

>>> print dir(skimage.filter)
['LPIFilter2D', '__all__', '__builtins__', '__doc__', '__file__', '__name__', '__package__', '__path__', '_canny', '_gabor', '_gaussian', '_rank_order', 'canny', 'denoise_bilateral', 'denoise_tv_bregman', 'denoise_tv_chambolle', 'deprecated', 'edges', 'gabor_filter', 'gabor_kernel', 'gaussian_filter', 'hprewitt', 'hscharr', 'hsobel', 'inverse', 'lpi_filter', 'prewitt', 'rank', 'rank_order', 'restoration', 'roberts', 'roberts_negative_diagonal', 'roberts_positive_diagonal', 'scharr', 'sobel', 'threshold_adaptive', 'threshold_isodata', 'threshold_otsu', 'threshold_yen', 'thresholding', 'vprewitt', 'vscharr', 'vsobel', 'wiener']


now the thing is can i fix this and why is it there ?

Appreciate any help on the matter.

Note : "from skimage import filter" works perfectly
