Can't import pyplot

[StephenFricke]

I am trying to use matplotlib within my script to create some graphs of some data.  When I try and import pyplot through matplotlib I get the following error....

When I try to import pyplot from matplotlib outside of ArcGIS inside the IDLE window everything works fine.  This seems odd to me considering the site packages for matplotlib are the exact same for running the script both in and outside of ArcGIS.  Does anyone know what may be the issue?  Thanks!

A common issue I see is that the PYDs are compiled with a manifest and expect a certain version of the Visual Studio C Runtime (MSVC*.dll) to be loaded in memory, and a different version is loaded in ArcMap.exe so it fails to load. The workaround is to find a build without a manifest in the PYD or rebuild the library yourself doing the same.

Hey thanks for the response.  I am sorry I am not very well versed in tech lingo.  I think the problem might have originally occurred when I added a bunch of enthought python modules to the c:/python27/ArcGIS10.1/Lib/Site-Packages directory.  All of the modules that I have tried which I added to this directory seem to work fine.  Importing matplotlib works fine as well but as soon as I try and import pyplot from matplotlib I get this huge error message.  Did I mess up the wiring for the matplotlib within ArcGIS when I added other modules from enthought to the ArcGIS site-packages directory?  Thank you!

I don't think they're messed up per se, I just think they might be incompatible, period. You may need to reinstall.

Try gettig the libraries you want from this site instead. (http://www.lfd.uci.edu/~gohlke/pythonlibs/)
