Hi all, today I installed PyFoam on Ubuntu 12.04 but something is wrong and when i run a case I have:
Code:
Traceback (most recent call last):
  File "/home/user-a5/OpenFOAM/PyFoam-0.6.3/bin/pyFoamPlotRunner.py", line 3, in <module>
    from PyFoam.Applications.PlotRunner import PlotRunner
ImportError: No module named PyFoam.Applications.PlotRunner
This is the procedure I used to install PyFoam
Code:
python setup.py install --prefix=$HOME/OpenFOAM/PyFoam-0.6.3
echo "alias PF062='export PYTHONPATH=\$HOME/OpenFOAM/PyFoam/PyFoam-0.6.3/lib/python2.7/site-packages:\$PYTHONPATH; export PATH=\$HOME/OpenFOAM/PyFoam/PyFoam-0.6.3/bin:\$PATH'" >> $HOME/.bashrc
Please, which is the problem?

Obviously the PYTHONPATH is wrongly set. Is there a directory PyFoam in $HOME/OpenFOAM/PyFoam/PyFoam-0.6.3/lib/python2.7/site-packages ?

Check with pyFoamVersion.py

BTW: it can't be the "in a new shell it works because I modified .bashrc but didn't source it in the original shell" problem?

Thank you for your quick reply, Bernhard. I obviously sourced the file .bashrc, after the modification :-)
I checked and the directory PyFoam really exists in $HOME/OpenFOAM/PyFoam/PyFoam-0.6.3/lib/python2.7/site-packages. Anyway I post the output of pyFoamVersion.py
Code:
PROBLEM: 
'from PyFoam.ThirdParty.six import print_' did not work. Seems that this is not the correct PyFoam-library

Well. This question solves about 50% of the "mysterious installation problems"

Is there a directory
/home/user-a5/OpenFOAM/PyFoam-0.6.3/lib/python-2.7/site-packages/PyFoam
and a file
/home/user-a5/OpenFOAM/PyFoam-0.6.3/lib/python-2.7/site-packages/PyFoam/Applications/PlotRunner.py

If there are not then you either didn't install PyFoam correctly or PYTHONPATH is pointing to the wrong location

I'm sorry Bernhard, I checked and everything is as expected. About PYTHONPATH, I think it points to the correct folder
Code:
alias pf='export PYTHONPATH=/home/user-a5/OpenFOAM/PyFoam-0.6.3/lib/python-2.7/site-packages:$PYTHONPATH; export PATH=/home/user-a5/OpenFOAM/PyFoam-0.6.3/bin:$PATH'
.
I really don't understand what happens :-(
Maybe other Python versions in my computer disturb PyFoam...

Don't think so. With all this lib/python-2.7-stuff python is quite good in separating installations.

The screenshots don't help. The titlebar with the path is unreadable. Plus comparing letter by letter for typos usually doesn't work. The only thing I trust is copying stuff from my config-file. "cd " and paste "<enter>" and see whether I'm in the correct directory

if we assume that your home folder path is correct (though I'd suggest using environment variable $HOME instead of /home/user-a5), final part of the path is wrong, it should be

Code:
lib/python2.7/site-packages
i.e. without minus.

so the alias should be something like

Code:
alias pf='export PYTHONPATH=$HOME/OpenFOAM/PyFoam-0.6.3/lib/python2.7/site-packages:$PYTHONPATH; export PATH=$HOME/OpenFOAM/PyFoam-0.6.3/bin:$PATH'

Dear Bernhard and Alexey, the problem was the '-' character. I apologize for having wasted your time, it was really a silly error :-(
As you can see, I've been far away from OpenFOAM and linux stuff for the last two years. Sorry again, have a good day.

PS Thanks for the $HOME tip too.

Dear All,

Happy New Year Wishes !!

I am using OpenFOAM 2.2.2 and i recently installed pyFoam 0.6.4 (installed it as a root). The installation was successfull but, when i try to use anyone of pyFoam commands say for instance ..
pyFoamChangeBoundaryType.py ... I get an error as shown below

Code:

PYFOAM_DIR missing from environment

Checking for PYFOAM_SITE_DIR : Location of non-PyFoam-disctributions script. Set and used by some Foam-distributions
PYFOAM_SITE_DIR missing from environment
Can someone tell me how to rectify this error ?

Checking additional envirnoment variables

Checking for PYFOAM_DIR : Location of the PyFoam-installation. Not strictly necessary
PYFOAM_DIR missing from environment

Checking for PYFOAM_SITE_DIR : Location of non-PyFoam-disctributions script. Set and used by some Foam-distributions
PYFOAM_SITE_DIR missing from environment
Can someone tell me how to rectify this error ?


That is strange. The function isatty should be defined right near the top of
/usr/local/lib/python2.7/dist-packages/PyFoam/Error.py

That is a completely fresh installation or did you upgrade from an old PyFoam installation? (but it must be really ancient because isatty is there for years)

Dear Bernhard Gschaider !

Thanks for your response !! I did a fresh installation of pyFoam 0.6.4... Is there any way to uninstall pyfoam ? I would like to reinstall it and try one more time...

You installed with setup.py, right? I'm afraid: no (http://stackoverflow.com/questions/1...p-py-uninstall)

You should be fine if you removed all files starting with pyFoam from /usr/local/bin and the whole directory /usr/local/lib/python2.7/dist-packages/PyFoam/

Quick answer: You need to update the package list first:
Code:
sudo apt-get update
Then you can try installing the package:
Code:
sudo apt-get install python-dev

Thank you again
but after doing the installation and enter the checking command

Code:
To test whether the installation of PyFoam is working start the interactive Python shell with 
   python (The shell can be left with Control-D). In that shell type 
   import PyFoam import PyFoam.FoamInformation print PyFoam.FoamInformation.foamTutorials() If the last command produces an output similar to 
   /home/nonroot/OpenFOAM/OpenFOAM-1.2-devel/tutorials everything is well.
I didn't get the output
how I can know it works fine?

Thank you
