Created attachment 838889 [details] steps to reproduce, and to patch the problem Description of problem: IOError: at /usr/lib64/python2.7/site-packages/PIL/Image.py:56 => line:56: "import _imaging as core" Version-Release number of selected component (if applicable): python-pillow-2.0.0-11.gitd1c6db8.fc19.x86_64 How reproducible: always Steps to Reproduce: 1. see attachment 2. 3. Actual results: exception IOError because method jpeg_decoder ABSENT in Image.core (alias _imaging) Expected results:jpeg_decoder found in Image.core Additional info: There is a (dirty) fix at the end of the attachment. ( re-import _imaging c lib and overwrite Image.core with the good import)
I cannot reproduce this: $ python Python 2.7.5 (default, Nov 12 2013, 16:18:42) [GCC 4.8.2 20131017 (Red Hat 4.8.2-1)] on linux2 Type "help", "copyright", "credits" or "license" for more information. >>> from PIL import Image >>> i=Image.open('image.jpg') >>> i.load() <PixelAccess object at 0x7fd070cda130> Also, jpeg support is tested when the package is built, so in principle it should work. Are there any environment particularities on your side? Does your script alter something to the environment before importing PIL and opening the image?
yes, thanks you can close the bug. It was caused by a second (illegal) _imaging.so under the PIL directory. I presume that I installed with "pip", some day and when i installed it, libjpeg-dev was missing. so the bug is for me : the first import in the Image.py: "import _imaging as core" found the "bad" pip _image.so in the PIL directory i.e /usr/lib64/python2.7/site-packages/PIL/. The patch i.e the same statement "import _imaging as core" found the right _image.so i.e : "rpm -qf /usr/lib64/python2.7/site-packages/_imaging.so" says : python-pillow-2.0.0-11.gitd1c6db8.fc19.x86_64. To Finish i consider it WOULD BE BETTER, as PIP does, in the rpm distribution to move the C modules (.so lib) under /usr/lib64/python2.7/site-packages/PIL/ because these modules belong to PIL and that the correct way (pure python) to import these modules (since python 2.5) it "from PIL import _imaging"
In F20+ the *.so modules are indeed in /usr/lib{64}/python2.7/site-packages/PIL/. It was an upstream change for python-pillow-2.1+ (see [1]). Since pillow is a core dependency for many packages, I won't be updating to a newer version in F19 however in the interest of stability. [1] https://github.com/python-imaging/Pillow/pull/191
