The 'image not found' error while importing matplotlib.pyplot #27

Closed yashchitalia closed 11 years ago

yashchitalia commented 11 years ago

Hi Chris, I'm trying to import matplotlib.pyplot into my python code to plot a few figures, but I get the following error when I run the import command.

ImportError: dlopen(/Library/Python/2.7/site-packages/matplotlib-1.3.x-py2.7-macosx-10.8-intel.egg/matplotlib/backends/_macosx.so, 2): Library not loaded: /System/Library/Frameworks/CoreText.framework/Versions/A/CoreText
  Referenced from: /Library/Python/2.7/site-packages/matplotlib-1.3.x-py2.7-macosx-10.8-intel.egg/matplotlib/backends/_macosx.so
  Reason: image not found

I tried searching the problem and noticed that someone else had the same sort of an issue 6 months ago, and had posted here. However, I don't really know whether it was the same issue, and I didn't really understand the solution to the issue. Could you help me out here?

Thanks, Yash

fonnesbeck commented 11 years ago

Yash,

It looks like you may be running 32-bit python. Can you confirm this? Try running:

arch -x86_64 python

then import matplotlib, and see if it works.

Hi Chris, Thanks for your reply! I tried what you advised, but got the same error. Here's a snapshot of the whole error:

I'd noticed a thread before this one that had a similar issue, and reinstallation using 'pip' had helped. Now, since I did not install using pip, I was unsure about how to go about the solution, and whether that situation even applies to my case. Thanks, Yash

yashchitalia commented 11 years ago

Chris, Although, I must add, during installation, after I ran the shell script, I did get a lot of warnings. Is that normal? It did install completely though. Unfortunately, I don't know how to bring up the warnings up again. In such a case, will reinstalling help? Thanks, Yash

fonnesbeck commented 11 years ago

It would be useful to see the complete output of the install, yes.

yashchitalia commented 11 years ago

Actually, I'm unable to retrieve the output of the install. Could you direct me to how I could procure it? Also, if that isn't possible, how do I reinstall?

christinasc commented 11 years ago

I had this problem a week ago when i updated my fonnesbeck install.

The matplotlib 1.3 is ok up until you do import matplot.pyplot -- that's when it fails on the mac.

The only way I fixed the problem was to revert to matplotlib 1.2 and edit the .pth file.

You can also try symlinking the /System/Library/Frameworks/ CoreText.framework/Versions/A/CoreText

as this was the solution discussed on some forums, but i declined to do this as I'd probably forget about it. I prefer to have a fully working version.

Hi Christina, Thanks a lot for the solution. However, I'm a bit lost about what to do (I'm just beginning with Python). Could you help me out with how I could go about getting the matplotlib 1.2 , because I couldn't find it here. Thanks, Yash

christinasc commented 11 years ago

https://github.com/matplotlib/matplotlib/downloads

for the 1.2 version

then look at your easy_intall.pth to see what version of matplotlib is listed.

it should be in the /Library/Python/2.7/site-packages/ directory

Christina, Thanks a lot again. However, how did you get the matplotlib 1.2 to install on python 2.7.1 as you have written on this link: http://stackoverflow.com/questions/12518098/failed-import-matplotlib-pylab-due-to-backends-macosx-so-reason-image-not-f/14782863#14782863 ? When I try to install the .dmg file for matplotlib 1.2 , it always gives me an error saying that : matplotlib1.2 requires System Python 2.7 to install. I too have a Python 2.7.1 that came preinstalled in my OSX Lion.

christinasc commented 11 years ago

2.7.1 works! That's exactly what i have. I can take a closer look tomorrow , going offline now.

Sure, thanks a lot!

yashchitalia commented 11 years ago

Christina, This is something I noticed just now. In all the installer packages on the link: https://github.com/matplotlib/matplotlib/downloads before the install, it mentions that the matplotlib1.2 is not for "Apple's built in python". So you probably installed your version from somewhere else? Thanks, Yash

christinasc commented 11 years ago

dunno - this is what i have. it works when i do from pylab import * and plot(y) also import matplotlib.pyplot works.

Okay, but how did you install matplotlib1.2 ? (When I run the .dmg files, the installer says that the version of python must not be the built-in python )

christinasc commented 11 years ago

can't remember. but you can do a search on stack overflow to see what people have done
