Hi Cory,
I am trying again to install paraview 5.3. I have downloaded it from the
paraview webpage. I am using Ubuntu 16.04 LTS; OS type 64-bit. Then I
followed these steps:
tar xzvf ParaView-5.3.0-Qt5-OpenGL2-MPI-Linux-64bit.tar.gz
sudo mv ParaView-5.3.0-Qt5-OpenGL2-MPI-Linux-64bit /opt/
sudo emacs ~/.bashrc # and added the following lines:
export PATH=$PATH:/opt/ParaView-5.3.0-Qt5-OpenGL2-MPI-Linux-64bit/bin/
export
PYTHONPATH=$PYTHONPATH:/home/doriad/bin/ParaView/Utilities/VTKPythonWrapping/site-packages
#fixes "no module named paraview"
export PYTHONPATH=$PYTHONPATH:/home/doriad/bin/ParaView/bin #fixes
"ImportError: No module named libvtkCommonPython"
export
PYTHONPATH=$PYTHONPATH:/opt/ParaView-5.3.0-Qt5-OpenGL2-MPI-Linux-64bit/lib/python2.7/site-packagesexport
PYTHONPATH=$PYTHONPATH:/opt/ParaView-5.3.0-Qt5-OpenGL2-MPI-Linux-64bit/lib/paraview-5.3
Saved and exit
#Created the symbolic links
sudo ln -s /opt/ParaView-5.3.0-Qt5-OpenGL2-MPI-Linux-64bit/
/usr/bin/paraview
sudo ln -s /opt/ParaView-5.3.0-Qt5-OpenGL2-MPI-Linux-64bit/
/usr/lib/paraview
#Restarted the computer and then executed:
./paraview
And paraview opens and works fine.
# Execute the script I mentioned in previous emails:
./<the name of the script>
And the following error message appears:
Error: Could not import vtkCommonComputationalGeometry
Traceback (most recent call last):
File "./<name of script>", line 42, in <module>
from paraview.simple import *
File
"/opt/ParaView-5.3.0-Qt5-OpenGL2-MPI-Linux-64bit/lib/python2.7/site-packages/paraview/simple.py",

line 9, in <module>
from vtkCommonCorePython import *
ImportError: No module named vtkCommonCorePython
Then I tried running it by using:
./pvpython <name of script>
And the error message is the following:
bash: ./pvpython: No such file or directory
I have also tried by using:
/opt/ParaView-5.3.0-Qt5-OpenGL2-MPI-Linux-64bit/bin/pvpython <name of script>
And the message is:
/opt/ParaView-5.3.0-Qt5-OpenGL2-MPI-Linux-64bit/lib/paraview-5.3/libgfortran.so.3: version `GFORTRAN_1.4' not found (required by /usr/lib/libarpack.so.2)

File "/opt/ParaView-5.3.0-Qt5-OpenGL2-MPI-Linux-64bit/lib/python2.7/site-packages/paraview/simple.py", line 846, in OpenDataFile
raise RuntimeError (msg)
My python version is (python --version) Python 2.7.12
My script starts with:
#!/usr/bin/python
import re,sys,os,shutil
-- and I also use --
from paraview.simple import *
Sorry for the inconveniences.
Really grateful,
Guillermo S.
