A few weeks ago I posted a problem with Mac OS X with matplotlib in the SAGE distribution in which attempting to import pylab gave an error message which stated that there was an import error and the module _tkagg could not be found. The problem appears to be with matplotlib (I'm not clear about this). After much searching and some emailing I have found a solution to this problem and it is easy to do.
Full credit goes to Eric Sonnendrucker who sent it to me. Here it is: 1) Download the Tcl/Tk sources (go to http://www.tcl.tk/, click on Get Tcl/Tk Now, click on Sources Download Page,, download the latest version). 2) In the Terminal cd to the unix folder in the tcl folder. Compile the unix version (of Tcl and Tk) as follows ./configure --enable-framework --disable-xft make make install 3) Install SAGE from source. Download the SAGE source code (go to http://www.sagemath.org/, click on Download, click on Download complete source code). In the terminal cd to the SAGE folder and *before* you run the sage install you need to set SAGE_MATPLOTLIB_GUI=True by using export SAGE_MATPLOTLIB_GUI=True with bash. The installer then picks it up automatically. Complete the SAGE installation by typing make and hit return. That's it. This will take a while (up to a few hours depending on the computer). 4) You might also need to modify your matplotlibrc by setting backend='TkAgg' after the installation Test this by doing an import pylab in sage. You should not get an error. -- To post to this group, send email to sage-support@googlegroups.com To unsubscribe from this group, send email to sage-support+unsubscr...@googlegroups.com For more options, visit this group at http://groups.google.com/group/sage-support URL: http://www.sagemath.org
