Re: [Matplotlib-users] Any available backend for non-root users?
Thank you Ben, I did use -X option upon ssh and I am running linux locally. The DISPLAY variable is automatically "localhost:17.0", where the number 17 changes for each login. But Tk would not work even after I export a new value to DISPLAY like ":0.0". I even tried reinstalling matplotlib (from source or through easy_install) with both values of DISPLAY but it always warns that Tk window failed to open. When I try to use TkAgg, it says ... import matplotlib.backends.tkagg as tkagg File "/ccs/home/lag69/.local/lib/python2.7/site-packages/matplotlib-1.1.0-py2.7-linux-x86_64.egg/matplotlib/backends/tkagg.py", line 1, in import _tkagg ImportError: No module named _tkagg So far I haven't solved this problem and I have to generate png files to view them (I can view them by xview or display of ImageMagick so the x11 forwarding does work) This is odd, and I almost lost my patient to try. But I still want to appreciate your generous help, Ben. regards, Liang On Thu, Aug 16, 2012 at 4:54 PM, Benjamin Root wrote: > > > On Thu, Aug 16, 2012 at 4:26 PM, Liang Wang wrote: > >> Hi everyone.

In other words, you won't be able to do a show() call, but you can save to any of the image formats. The TkAgg backend should also be an option (unless that python was built without Tk, which is rare). Often, if Tk isn't working, it is a simple matter of setting your display environment correctly. Most of the time, simply passing the "-X" option to ssh is sufficient (assuming you are sshing from a linux box). Otherwise, I think you have to mess around with your DISPLAY environment variable on the remote server (I think it is usually ":0.0", but I am no expert on this. I hope that helps!
