Unable to import matplotlib.pylab in Windows

Should have asked this before: Does your computer's CPU have SSE2 extensions? You can use CPU-Z <http://www.cpuid.com/>.

It is OK that Dependency Walker does not find MSVCR90.DLL and MSVCP90.DLL for a PYD extension. The extension will use whatever VC90.CRT python26.dll uses at runtime.

I am not able to reproduce your problem using a fresh Windows XP SP3, Python 2.6.4, numpy 1.3.0, matplotlib 0.99.1 installation in VirtualPC.

If you don't mind, would you try installing <matplotlib-0.99.1.1.win32-py2.6.exe> from <http://www.lfd.uci.edu/~gohlke/pythonlibs/#matplotlib>. This build has SSE2 disabled and a manifest for VC90.CRT embedded, which explicitly specifies the VC90.CRT to use.

Christoph, you were right about the lack of SSE2 support. CPU-Z says that my laptop has only SSE support.

However, when I downloaded your build and installed it, I still have the same problem.

Thanks for all your help on this.

Dilip.
