#41449: py-ipython: ipython notebook does not support inline plots (ImportError: No module named _backend_agg) -----------------------+------------------------ Reporter: aronnax@… | Owner: akitada@… Type: defect | Status: new Priority: Normal | Milestone: Component: ports | Version: 2.2.1 Keywords: | Port: py-ipython -----------------------+------------------------ The IPython port (py27-ipython +notebook) does not support inline plots. Start up IPython with: {{{ $ ipython notebook --pylab=inline }}} Then, enter and execute the following code cell: {{{ from matplotlib import pyplot as plt import numpy as np plt.plot(np.arange(10), np.arange(10)) plt.show() }}} One gets the following traceback: {{{ --------------------------------------------------------------------------- ImportError Traceback (most recent call last) <ipython-input-3-1505639dfc55> in <module>() ----> 1 from matplotlib import pyplot as plt 2 import numpy as np 3 plt.plot(np.arange(10), np.arange(10)) /opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7 /site-packages/matplotlib/pyplot.py in <module>() 96 97 from matplotlib.backends import pylab_setup ---> 98 _backend_mod, new_figure_manager, draw_if_interactive, _show = pylab_setup() 99 100 /opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7 /site-packages/matplotlib/backends/__init__.pyc in pylab_setup() 26 # imports. 0 means only perform absolute imports. 27 backend_mod = __import__(backend_name, ---> 28 globals(),locals(),[backend_name],0) 29 30 # Things we pull in from all backends /opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7 /site-packages/IPython/kernel/zmq/pylab/backend_inline.py in <module>() 8 # Third-party imports 9 import matplotlib ---> 10 from matplotlib.backends.backend_agg import new_figure_manager, FigureCanvasAgg 11 from matplotlib._pylab_helpers import Gcf 12 /opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7 /site-packages/matplotlib/backends/backend_agg.py in <module>() 36 from matplotlib.transforms import Bbox, BboxBase 37 ---> 38 from matplotlib.backends._backend_agg import RendererAgg as _RendererAgg 39 from matplotlib import _png 40 ImportError: No module named _backend_agg }}} -- Ticket URL: <https://trac.macports.org/ticket/41449> MacPorts <http://www.macports.org/> Ports system for OS X
