Empty or error streamline demo

[Дмитрий Долгов]

I have installed scitools on gentoo (with vtk,matplotlib and etc.)

When i run streamline_demo1.py with matplotlib backend, i'd got empty result.

When i run streamline_demo1.py with vtk backend, i'd got error:

 

Traceback (most recent call last):

  File "streamline_demo1.py", line 27, in <module>

    streamline(x, y, z, u, v, w, sx, sy, sz,view=3, axis=[60,140,10,60,-5,20])

  File "/usr/lib64/python2.7/site-packages/scitools/easyviz/common.py", line 3799, in streamline

    self._replot()

    sgrid = self._get_2d_structured_grid(item, vectors=True)

  File "/usr/lib64/python2.7/site-packages/scitools/easyviz/vtk_.py", line 540, in _get_2d_structured_grid

    sgrid.SetDimensions(item.getp('dims'))

TypeError: argument 1: expected a sequence of 3 values, got 1 values

 

With other streamline demo and vtk backend is there dark screen as result. What is the error cause? How i can fix this error?

I found the cause of the error - i compiled vtk without tk support.
