I've built matplotlib-1.4.3 with Python 2.7.5, 3.3.2, 3.4.3. Python 3.3.2 and 3.4.3 work ok. With Python 2.7.5, I get: File "/tmp/lines3d_demo.py", line 2, in <module> from mpl_toolkits.mplot3d import Axes3D ImportError: No module named mpl_toolkits.mplot3d There is no __init__.py in the mpl_toolkits directory unlike with matplotlib-1.3.1: $ ls -l /opt/TWWfsw/matplotlib14/lib/python27/mpl_toolkits total 64 drwxr-xr-x+ 2 root root 53 Jul 14 13:51 axes_grid drwxr-xr-x+ 2 root root 32 Jul 14 13:51 axes_grid1 drwxr-xr-x+ 2 root root 29 Jul 14 13:51 axisartist -rw-r--r--+ 1 root root 3830 Dec 23 2014 exceltools.py -rw-r--r--+ 1 root root 3817 Jul 14 13:51 exceltools.pyc -rw-r--r--+ 1 root root 3817 Jul 14 13:51 exceltools.pyo -rw-r--r--+ 1 root root 19346 Dec 23 2014 gtktools.py -rw-r--r--+ 1 root root 19745 Jul 14 13:51 gtktools.pyc -rw-r--r--+ 1 root root 19706 Jul 14 13:51 gtktools.pyo drwxr-xr-x+ 2 root root 17 Jul 14 13:51 mplot3d drwxr-xr-x+ 3 root root 12 Jul 14 13:51 tests If I copy the matplotlib-1.3.1 __init__.py to /opt/TWWfsw/matplotlib14/lib/python27/mpl_toolkits, then everything works ok. -- albert chin (ch...@th...)

Maybe your python 2.7 setuptools needs to be updated? Eric

Looking at a Fedora 22 system, matplotlib-1.4.3-py2.7-nspkg.pth is read, but not on our system. This is the problem. If I move this file out of the way on the Fedora 22 system, the failure is the same as above. Just need to figure out how Python reads this file. -- albert chin (ch...@th...)

Python only reads .pth files in the default Python prefix (sys.prefix and sys.exec_prefix), not from any other path in PYTHONPATH. I'll need to create sitecustomize.py to fix this. -- albert chin (ch...@th...)
