So just do from a python prompt "import sys; sys.path" and check if the VTK directories are listed. Interesting. sys.path includes this path: 'C:\\Documents and Settings\\mbog002.EC\\ C:\\Program Files\\VTK\\lib\ \site-packages' The first part is what I set the environment variable HOME to (as per Enthought instructions), the second part is the VTK path. Apparently the specified VTK path is being made relative to HOME - clearly inconsistent with the installation instructions. Your VTK path starts with a space, and that confuses the path manipulations. I solved the problem by editing PYTHONPATH in the registry. Definitely a trap for Windows users. If you set the VTK path to an absolute path, this should not happen. -- Gabriel Genellina -- http://mail.python.org/mailman/listinfo/python-list

You colòud aslo tentatively append your path to sys.path and then try again import vtk to see if it is a path problem or something else ...

VTK install
As part of the MayaVi install, I need to install VTK. Follwoing the Enthought instructions, I went here: http://cpbotha.net/2009/08/13/python-2-6-enabled-vtk-5-4-windows-binaries/ and installed vtk-5.4. I modified the PATH and also created an environment variable PYTHONPATH as directed, setting it to be C: \Program Files\VTK\bin; C:\Program Files\VTK\lib\site-packages; According to Botha's instructions, I should now be able to do 'import vtk', but this doesn't work: no module named vtk. Since VTK appears to be installed, I'm guessing that either the path setting is wrong, or python is not using PYTHONPATH. How can I check that PYTHONPATH is being used? -- http://mail.python.org/mailman/listinfo/python-list
