Just tinkering, I wondered if this was related to having multiple versions of Python installed. When auto-config / build scripts are being run I always have a niggling feeling of unease in a multiple-version environment. Looking at the multi-version support in OS X, I came across this nugget to set a global default version to execute: sudo defaults write /Library/Preferences/com.apple.versioner.python Version 2.7 It looks like the modules are now importing properly. Perhaps worth adding to the install page as a Mac OS X note? Yours, James. On Sat, Feb 14, 2015 at 6:17 PM, James Jackson < james.a.f.jackson.2@googlemail.com> wrote:

Josh,

Thanks for the reply - I've just installed cython using the requirements file so should be up-to-date. Looking back at my install log, it seems I've got the latest (0.22).

Collecting cython>=0.21 (from -r requirements.txt (line 1)) Downloading Cython-0.22-cp27-none-macosx_10_6_intel.macosx_10_9_intel.macosx_10_9_x86_64.macosx_10_10_intel.macosx_10_10_x86_64.whl (3.7MB)

Looking in the site-packages directory I do see a _hough_transform library:

James-Jacksons-MacBook-Air:transform jamesjackson$ pwd /Library/Python/2.7/site-packages/skimage/transform James-Jacksons-MacBook-Air:transform jamesjackson$ ll | grep hough -rwxr-xr-x 1 root wheel 659580 14 Feb 09:41 _hough_transform.so -rw-r--r-- 1 root wheel 5566 14 Feb 09:41 hough_transform.py -rw-r--r-- 1 root wheel 5044 14 Feb 09:41 hough_transform.pyc

So something funny is clearly going on here with it not being picked up...

Yours, James.

Hi James,

These are Cython modules that aren't being found or are not properly compiling. Please let us know what version of Cython you are running.

Rest assured the modules are there. These are not external dependencies. I suspect an old version of Cython is to blame.

Hi,

I'm trying to install skimage, and having installed the dependencies (from requirements.txt in the source release), and then using pip to install skimage itself, I am having problems importing the transform

This is on Mac OSX 10.8.4 with Python 2.7.2. Is this an external

darwin library that needs installing from somewhere else? I have already had to install tifffile separately to get skimage.data working (perhaps should be added to requirements.txt?). I've tried a variety of approaches, but haven't had any success.

Any and all advice welcome!
