h5py import error QGIS python console

[timlarson284]

I have windows 64bit installation of QGIS 2.18.3. This includes a python2.7 environment as part of the package.

I used OSGeo shell to install h5py using pip install. I got the wheel with windows binaries from here http://www.lfd.uci.edu/~gohlke/pythonlibs/#h5py

h5py works fine in OSGeo shell, however when I open QGIS and go to the Python Console, which should be using the same python install and packages as the OSGeo shell, I get this error:

import h5py
Traceback (most recent call last):
File "", line 1, in
File "C:/PROGRA2/QGIS21.18/apps/qgis/./python\qgis\utils.py", line 607, in _import
mod = builtin_import(name, globals, locals, fromlist, level)
File "C:\PROGRA2\QGIS21.18\apps\Python27\lib\site-packages\h5py_init.py", line 24, in
from . import _errors
ImportError: cannot import name _errors

Any help on why this works in OSGeo and not in QGIS Python console is appreciated.

Thanks!
Tim

It's probably an expected conflict of the HDF5 DLLs shipped with QGIS/OSGeo and h5py. Hence the warning at the beginning of http://www.lfd.uci.edu/~gohlke/pythonlibs/ . The solution would be to rebuild h5py against the specific version of the HDF5 library shipped with OSGeo or better against a custom build of HDF5 with different DLL names.

Btw, I get a different Traceback, which makes more sense:

@jef-n am I correct in understanding that h5py is now shipped with QGIS? Who from QGIS should be added to the list of people we contact about new releases?

[tacaswell]

Closing as fixed by down-stream packaging.

@jef-n There will be a 2.8 (and maybe a 2.7.2) in the very near future.

You are apparently not using QGIS packages (ie. OSGeo4W).
