It was a good guess. You have a software version conflict apparently, and yet you haven't provided us any version numbers of the packages you are using -- that makes it pretty hard to progress. One thing I notice is that you import Numeric, which is the predecessor to numpy. All recent versions of matplotlib/pylab import numpy by default, though some older versions can be configured to use Numeric, numarray or numpy using a numerix setting. It is possible that you are seeing a Numeric/numpy conflict somewhere. I am not sure what openbabel and pybel are doing internally vis-a-vis numpy/numeric, though I do see that there are some problems passing numpy scalars to openbabel at http://openbabel.org/wiki/Python. > Could you recommend other "easy to handle " python plotting libs? chaco is quite nice - http://code.enthought.com/chaco. But we would like to sort out this problem for future reference, so if you'd be willing to stick with it and help us figure out where the conflict is coming from, it will help the future users. My first suggestion is to see if you need Numeric, or if numpy will suffice, and make sure you are using it consistently throughout. My second suggestion is to figure out of there are any gui toolkits in the openbabel chain, and if so make sure your backend setting in matplotlib is consistent with them (though the gui mainloop will not be triggered by simply importing pylab, you must also call pylab.show, so I don't know why that would cause a problem per se). In any follow-up emails, please post the versions of all software you are importing. One could way to get the matplotlib version info is to create a simple script:: import pylab pylab.plot([1,2,3]) pylab.show() and run it with:: > python myscript.py --verbose-helpful and post the output here.
