[Paraview] Paraview and Python related question

I have tried setting that too, but it doesnt work. Perhaps its some weird combination of python, tkinter installed using macports with paraview 4.4 pre-built-binary that requires some special trick. I will try on Linux sometimes.

Hi,

I think you should *add* the Paraview
path to the environment variable. Now
you overwrite it. So the typical syntax
is (bash):

export avar=adir:$avar

(Send from my phone, so I hope the formatting is reasonable).

There is this weird behaviour :

fluid:~ armando$ export DYLD_LIBRARY_PATH=/lib
fluid:~ armando$ idle

idle works just fine even if I point DYLD_LIBRARY_PATH to anything… as in above example /lib

But when I set it to paraview:

fluid:~ armando$ export DYLD_LIBRARY_PATH=/Applications/ArmandoApps/paraview.app/Contents/Libraries/
fluid:~ armando$ idle
** IDLE can't import Tkinter.
Your Python may not be configured for Tk. **

I get tkinter error.

Any ideas anyone please ?

Regards

Thanks for the help. When I set DYLD now the idle stops working:

fluid:~ armando$ export DYLD_LIBRARY_PATH=/Applications/ArmandoApps/paraview.app/Contents/Libraries/:$DYLD_LIBRARY_PATH
fluid:~ armando$ export PYTHONPATH=/Applications/ArmandoApps/paraview.app/Contents/Python/vtk:/Applications/ArmandoApps/paraview.app/Contents/Python:$PYTHONPATH
fluid:~ armando$ idle
** IDLE can't import Tkinter.
Your Python may not be configured for Tk. **

I have python and py-tkinter installed using macports and if I open a new terminal, idle just works fine.

I am searching on Macports / python and other forums… if anyone on paraview list has encountered it before please let me know.

Regards

Hi Amit,

Since you appear to be using OSX, the environment variable you want is DYLD_LIBRARY_PATH, not LD_LIBRARY_PATH.

HTH,

Hi

I downloaded the Paraview app and put it in a folder. Then I tried following instructions on this page: http://www.paraview.org/ParaView3/Doc/Nightly/www/py-doc/quick-start.html

export PYTHONPATH=/Applications/ArmandoApps/paraview.app/Contents/Python:$PYTHONPATH
export LD_LIBRARY_PATH=/Applications/ArmandoApps/paraview.app/Contents/Libraries/:$LD_LIBRARY_PATH

and I get this error:

Python 2.7.10 (default, Sep 14 2015, 23:52:44)
[GCC 4.2.1 Compatible Apple LLVM 6.1.0 (clang-602.0.53)] on darwin
Type "copyright", "credits" or "license()" for more information.
>>> from paraview.simple import *
Error: Could not import vtkCommonComputationalGeometryPython

Traceback (most recent call last):
  File "<pyshell#0>", line 1, in <module>
    from paraview.simple import *
  File "/Applications/ArmandoApps/paraview.app/Contents/Python/paraview/simple.py", line 39, in <module>
    import servermanager
  File "/Applications/ArmandoApps/paraview.app/Contents/Python/paraview/servermanager.py", line 48, in <module>
    import paraview, re, os, os.path, new, sys, atexit, vtk
  File "/Applications/ArmandoApps/paraview.app/Contents/Python/paraview/vtk/__init__.py", line 7, in <module>
    from vtkCommonCorePython import *
ImportError: No module named vtkCommonCorePython
>>>

When i add vtk subfolder also to PYTHONPATH, I get this error:

ImportError: dlopen(/Applications/ArmandoApps/paraview.app/Contents/Python/vtk/vtkCommonCorePython.so, 2): Library not loaded: @executable_path/../Libraries/libvtkCommonCorePython27D-pv4.3.1.dylib
  Referenced from: /Applications/ArmandoApps/paraview.app/Contents/Python/vtk/vtkCommonCorePython.so
  Reason: image not found

vtkCommonCorePython.so is present in LD_LIBRARY_PATH set earlier.

So question is: Am I following correct instructions ?

I guess there are three scenarios I would be working with in coming days:

1. python code to run default python.app on my local MacOS, read H5Part file and visualize it.
2. python code to run compiled python on my cluster
3. python code to run compiled python server on my cluster

I dont know yet what would the difference in 2nd and 3rd point but for now I am trying to write a python script that would start python and open a file and visualize it.

Any help would be highly appreciated.

Regards

Amit
