Thanks for the replies. That fixed it but produced another problem. There are two plotting routines below. Either one will work without error. But the combo produces: The exception unknown software exception (0x40000015) occurred in the application at location 0x1e05b62a. in a dialog box and the following in the console Fatal Python error: PyEval_RestoreThread: NULL tstate
This application has requested the Runtime to terminate it in an unusual way. Please contact the application's support team for more information. Do you see what isa wrong? Second question: Is it common to group all the "from" statements at the top of the program or to put them by the relavent code as I have here? Thanks a lot try: #Or we can use the two commented statements #from ffnet.tools import drawffnet from ffnet.tools.drawffnet import drawffnet import pylab #drawffnet.drawffnet(nn) drawffnet(nn) pylab.show() except ImportError, e: print "Cannot make drawffnet plot.\n%s" % e ? ? # Plot adapted from # http://ffnet.sourceforge.net/examples/stock.html # Make plot if matplotlib is avialble try: from pylab import * plot( targets2, 'b--' ) plot( output, 'k-' ) legend(('target', 'output')) xlabel('pattern'); ylabel('benign or malignant') title('Outputs vs. target of trained network.') grid(True) show() except ImportError, e: print "Cannot make plots. For plotting install matplotlib.\n%s" % e ? ? -- http://mail.python.org/mailman/listinfo/python-list
