Hello,
I installed the binary for VTK 5.0.1, but there were no Python
bindings. So I uninstalled and tried to install from the source, but no
luck. Eventually I just unzipped the files from
VTK-6.4.2-Python-2.4.1.zip (not a typo, this is the name of the file,
though I guess it should be 4.4.2) and got an apparently working
installation. (I also installed ActiveTCL prior to this.)
I unzipped MayaVi-2.5.zip (not a typo) to my C drive and ran setup.py
install; everything seemed OK.
All the tests in test_vtk.py seem to pass.
But if I try the following (more or less copied directly from the
documentation) I have a problem.
>>> import Tkinter
>>> r = Tkinter.Tk()
>>> r.withdraw()
''
>>> import mayavi
>>> v = mayavi.Main.MayaViTkGUI(r)
>>> v.load_visualization('c:\MayaVi-1.5\examples\heart.mv')
The window hangs until I restart the shell.
A little editing allows me to get a traceback,
Traceback (most recent call last):
File "<pyshell#5>", line 1, in -toplevel-

lut_v, r_on, v_r_on, v_d_r = eval (val)
File "<string>", line 0, in -toplevel-
NameError: name 't' is not defined
although the line numbers will be a little out due to a few print
statements that I added.
It seems that 'val' is a string (the end of the line in heart.mv
containing 'custom16.lut\n'). Any clue whether this is a problem with
my installation, or something else? BTW, executing MayaVi.pyw from
C:\Python\Scripts does not open a window, and C:\MayaVi-1.5\mayavi has
not been renamed (which I expected after glancing at setup.py). Any
help much appreciated.
