Please always poste the complete output of the utility and let me judge what is needed. As far as I can see you still got the Paraview-binaries in the PYTHONPATH. At the very least this breaks numpy (because you use Python 2.7, Paraview 2.6). Not sure, but this probably also breaks VTK.

So remove all parts pointing to the Paraview-installation from the PYTHONPATH and retry

Ok, I do in this way:
run Python
import sys
print sys.path
import paraview
import vtk

and this in my pyFoamVersion.py

As I suspected: Paraview is in the PYTHONPATH. Completely erase the path with 'unset PYTHONPATH' and retry

The VTK-version that comes with Paraview is NO help. For some technical reason (you'll have to research that yourself) the version of VTK that comes with Paraview is modified and in parts behaves differently. Make sure you use the version from MacPorts (I think I described that before)

this is my version of ports
the pyFoam doesn't recognize the vtk and the installation with port that you already suggested didn't work with python. Do you know another way to install vtk to work with pyFoam. I tried to use Homebrew but I have not had any success.

I already explained it to you in a previous post (http://www.cfd-online.com/Forums/ope...l#post423691): install the vtk from MacPorts! I assumed you've already done that and the library was "shadowed" by the paraview-version

I already install the vtk5! but I really don't know why this doesn't work.

Which python-version are you using? From the version reported I guess the apple-version in /usr/bin/python (but please verify with "which"). I use the MacPorts-version and the variant +python27 of vtk5 assumes that. Either select the MacPorts-version with "port select python python27" or reinstall vtk5 without that option (but I haven't tested that)

error messages running pyFoamPlotRunner
 

hello

i installed pyFoam on a rhel server but if i run pyFoamPlotRunner

with the syntax

pyFoamPlotRunner.py <OFsolver> -case CASE

pyFoamPlotRunner.py <OFsolver> (in the case folder)


i get following error messageTraceback (most recent call last):
File "/usr/bin/pyFoamPlotRunner.py", line 3, in ?
from PyFoam.Applications.PlotRunner import PlotRunner
File "/usr/lib/python2.4/site-packages/PyFoam/Applications/PlotRunner.py", line 6
from .PyFoamApplication import PyFoamApplication

SyntaxError: invalid syntax



i would be happy about any help or recommendations

i m running pyFoam0.6.2

At first: please add output in the CODE-tag (that's be the # in the toolbar above). It makes it much easier to spot where the ^ is actually pointing to.

What kind of RHEL? My guess is that it is not 6. Because the problem you have is one of the rare backward incompatibilities in Python. Relative imports were introduced with python 2.5 (so your Python seems to be 2.4 or older). Ah. Just saw it: it says 2.4 in the output

Options are:
- make the import absolute (just add PyFoam.Applications in front of the dot). Don't know where else this is required. Or make it "oldSchool"-relative by removing the dot in the front
- there are packages python26 or python27 for RHEL that give you a higher-version PyFoam in parallel to the system on (don't EVER replace the system-python on a RHEL-machine). Using that needs a little bit of trickery (especially if you use setup.py)

The reason why PyFoam uses the new-style relative import is that the old way does not work with Python 3 (PyFoam is compatible with python 2.x and 3.x but in order to get that I had to break compatibility with Pythons older than 2.5)

oh sorry i didnt knew that

its RHEL 5.10. I already sent your advices to our admin (i m not root)

OK. Recommended is installing a python26/27 binary package and virtualenv. Then create a virtual environment in which you install dependencies. That leaves the system-python clean and allows you to use bleeding-edge versions of the python-packages (if your sysadmin is nice he does this for you). I use a similar setup here (CentOS6 is a LITTLE more advanced than your 5 but for fast-moving libraries like Pandas or Matlab it is hopelessly outdated)

pyFoamDisplayBlockMesh.py raise e AttributeError: SetInput
 

Hi,

I have a similar problem as is reported earlier and I can not find solution to that. My os is rhel 7.1 and same problem occur with pyFoam version 0.6.1 and 0.6.4. Error message is also similar with both pyFoam version.

error:
and

and

older pyFoam version

Thanks in advance

Quick answer @Pekka: VTK 6.1... I don't think that PyFoam is prepared for VTK 6.x, because the API changed considerably between VTK 5.x to 6.x.

How exactly did you install Qt 4.8 and VTK 6.1 in RHEL 7? Was it from the EPEL repositories?

Thank you Bruno!

Problem has been solved by downgrade vtk to older one. I compiled vtk-5.10.1-4 from fc19.src.rpm source package. vtk 6.1.0 is from epel repository.

Hello everyone

I know this thread is years old but I'm hoping someone will still be able help.

I'm trying to use the pyFoamDisplayBlockMesh function but keep getting the following error:

segmentation fault (core dumping).

with no further indication as to the cause of the error. I then set about compiling foam-extend 4 in debug mode which then gave me the following error:

mn14cat@mn14cat-XPS-13-7390:~/foam/mn14cat-4.1/run/tutorials/solidMechanics/elasticSolidFoam/plateHole$ pyFoamDisplayBlockMesh.py constant/polyMesh/blockMeshDict

VTK version 6
PyFoam WARNING on line 48 of file /home/mn14cat/foam/foam-extend-4.1/ThirdParty/packages/PyFoam-0.6.9/platforms/noarch/lib/python2.7/site-packages/PyFoam-0.6.9-py2.7.egg/PyFoam/Applications/DisplayBlockMeshQt.py : VTK version 6 currently unsupported
Segmentation fault (core dumped)

So my question is how would I go about downgrading my version of VTK and which version would be best to run displayMesh.py

thanks in advance and hopefully someone finds this.
