[Paraview] Import h5py in python shell

[Jean-Michel]

As it turns out, my python installation is 32 bits, which I wasn't aware of (checked it with platform.architecture).

Loading h5py in the python shell from ParaView 32 bits works fine after extending sys.path.

Anyway, thank you very much for your help.

Maybe try setting the PATH such that it finds the DLLs it's trying to loads -- it's a Hail Mary, but why not :).

Thanks again Utkarsh.

 

However, trying to load the installed h5py from pvpython (after appending the path in the sys.path) gives me the same error I ran into in ParaView's python shell:

 

from h5py import _errors

ImportError: DLL load failed: %1 is not a valid win32 application

Another trick to try (no guarantees :) ) is to install Python 2.7.2 (64bit)  and then install h5py for this installation of Python. Then, try loading h5py from pvpython. You'll need to extend  the sys.path variable to find the installed modules.

Thank you for your answer Utkarsh.

 

Unfortunately, the h5py installer for Windows does not find the Python installation packaged with ParaView in my registry, so I cannot install it in ParaView.

ParaView packages its own Python. You'll either need to build ParaView from source using the Python installation you have or install h5py in the Python packaged with ParaView.

Dear all,

 

I am currently trying to use the h5py module in the Python Shell in ParaView 4.3.1 (64 bits). On my system, h5py comes from my installation of python-xy and works fine outside of ParaView.

 

I tried to import the module by providing the path to the package, using mainly two methods:

- append the path to the package with sys.path.append before doing the import

- import the module using the imp package and providing the full path to imp.load_source

However, both methods failed to load h5py, returing the following error : "ImportError: DLL load failed: %1 is not a valid win32 application".

 

Thank you for your help.
