   It sounds like you somehow have two versions of matplotlib installed on top of each other.
   I suggest uninstalling matplotlib with conda and then making sure that all leftovers of matplotlib and mpl_toolkits are removed from /home/fzeng/anaconda/lib/python2.7/site-packages and then try again.

   Hi Nielsen, it works following your suggestions and thanks a lot. May I ask one more question that how do you find out there are two conflicting versions of matplotlib?

   It was just a guess. But there were two reasons

   • The six code was moved to external in 1.5 so it seems likely that some of your code is 1.5 and some of it older.
   • mpl_toolkits is a namespace package to allow basemap and other external packages to be installed into it. This makes it unreliable to uninstall when changing versions. I hope to be able to change this in a future version to avoid namespace packages.

   I am having this problem now, and re-installing matplotlib didn't help... Anything I might be missing? Ubuntu 16.04, installation of python 3.5 parallel with 2.7 (tried reinstalling maptlotlib in both installations).

   have you tried removing the matplotlib package provided through Ubuntu? The error seems to suggest that the mpl_toolkits is getting picked up in the dist-packages folder, which seems to be old.
