Hi Dhasthagheer,

I have just bumped on your post by accident. What for to wait so long for someone's answer if there is an official pythonFlu bug tracker?

About the question, have you checked whether the "pythonflu171_8.0-1_maverick_i386.deb" package you downloaded is whole or broken?
Run md5sum Linux utility to verify that it is equal to "d62a707aec5449826a6a0c37ac21a7fd".

Best regards,
Alexey

You are right. The package which I downloaded was broken. I downloaded again fresh pythonflu1.7 and installed successfully

HI !
I am new to OpenFoam.
I need check the my PC : 32bit or 64bit and so I have a "pythonflu" package conformable .
I checked whether the "pythonflu171_8.1-Elvis-1_maverick_i386.deb" package I downloaded.
However, it appeared error.
Plz, can you help me !
thanks ! :)

Hi phuchuynh

If you want to check your PC is 32 bit or 64 bit, you just type the following command in terminal

Code:

lscpu

It will display all the information of your CPU.

I have some question for you.

What Ubuntu version your are using?
What are the error your are getting?

Please post the error here

I have tried to reproduce your case.
I guess you have run the installation procedure for pythonFlu package more then once.
I confirm, that this is a bug in pythonFlu installation and we are going to fix it in next release (in about one month).
For now, we suggest the following workaround.

Remove the broken pythonFlu installation
sudo mkdir /usr/local/lib/python2.6/dist-packages/Foam
sudo touch /usr/local/lib/python2.6/dist-packages/Foam/__init__.py
sudo dpkg -r pythonflu171
Install pythonFlu once again
sudo dpkg -i <your path to>/pythonflu171_8.1-Elvis-1_maverick_amd64.deb
Check that pythonFlu was successfully installed
python -c "from Foam import finiteVolume; print finiteVolume"
Do not forget to install pythonFlu based solvers (http://pythonflu.wikidot.com/solvers) you want, for example
sudo easy_install icoFlux

Hope this will help,
Alexey

Hi alexey2petrov !
That is great ! :D
thanks for your help !

Best regards

Same problem with natty and same workaround.
You just have to change python2.6 with python2.7 in the procedure above

Thanks for the tip :)
