Follow-up Comment #1, bug #22939 (project relax): This issue can be reproduced as follows: 1) Start the relax GUI. 2) Open the relax prompt window (using "View->relax prompt" for example). 3) Type "import pylab as plt" This will result in: relax> import pylab as plt Traceback (most recent call last): File "<input>", line 1, in <module> File "/usr/lib64/python2.7/site-packages/pylab.py", line 1, in <module> from matplotlib.pylab import * File "/usr/lib64/python2.7/site-packages/matplotlib/pylab.py", line 269, in <module> from matplotlib.pyplot import * File "/usr/lib64/python2.7/site-packages/matplotlib/pyplot.py", line 98, in <module> _backend_mod, new_figure_manager, draw_if_interactive, _show = pylab_setup() File "/usr/lib64/python2.7/site-packages/matplotlib/backends/__init__.py", line 25, in pylab_setup globals(),locals(),[backend_name]) ImportError: No module named backend_wxagg When running relax in the prompt UI mode however, this matplotlib import works successfully. _______________________________________________________ Reply to this item at: <http://gna.org/bugs/?22939> _______________________________________________ Message sent via/by Gna! http://gna.org/
