am new to python and struglling to use the ipython on mac. Some body told me to use the anaconda, ipython notebook for help.
I installed the anaoconda on my mac. I have to use the numpy,scipy and matplotlib frameworks numpy, scipy works fine but the matplotlib thows error when I try to use it. or %pylab throws error.
I dont understand whats the problem?
Here's the screen shot for the same.
Here's the full trace enter link description here
Here's the error (full stacktrace) in case if Link doesn't work
