Greetings... I am working using the matplotlib version 0.90.1, and i am having some strange problems with my application. When i execute in some pcs, there is no problem at all, but in others pcs, i receive this message: File "pylab.pyc", line 1 in ? File "matplotlib\pylab.pyc", line 203 in ? File "matplotlib\axes.pyc", line 14 in ? File "matplotlib\agg.pyc", line 5 in ? File "matplotlib\_agg.pyc", line 12 in ? File "matplotlib\_agg.pyc", line 10 in ? ImportError: Dll Load Failed All the pc's have Windows Xp, most of them Pentium 4, some are Pentium D. I don't know what may be the issue. All those pcs have the same software, just different hardware, i hope you could help me with this little problem. Thanks in advance...
