I'm trying to build a 3d surface plot in python. From what I've read, this is the standard package: from mpl_toolkits.mplot3d import Axes3D However, I receive the following Error: ImportError: No module named mpl_toolkits.mplot3d This is the error message I receive when trying to install the package: Myname-MacBook-Pro:ex1 myname$ sudo pip install --upgrade matplotlib The directory '/Users/ryansullivan/Library/Caches/pip/http' or its parent directory is not owned by the current user and the cache has been disabled. Please check the permissions and owner of that directory. If executing pip with sudo, you may want sudo's -H flag.
