importError: DLL load failed(import h5py)

Question

I installed the OSGeo4W package to use h5py on a Windows environment.

I used OSGeo shell to install h5py using pip install.

C:\Users\Public\Desktop\OSGeo4W>pip install h5py

When I open QGIS and go to the Python Console in QGIS I get this error:

import h5py
Traceback (most recent call last):

I don't know how can use h5py in QGIS python console

Check this https://github.com/h5py/h5py/issues/828 . If you install using

pip install h5py

import h5py

Traceback (most recent call last):
  File "<input>", line 1, in <module>
  File "C:/OSGEO4~1/apps/qgis/./python\qgis\utils.py", line 607, in _import
    mod = _builtin_import(name, globals, locals, fromlist, level)
  File "C:\OSGEO4~1\apps\Python27\lib\site-packages\h5py\__init__.py", line 43, in <module>
    from . import h5a, h5d, h5ds, h5f, h5fd, h5g, h5r, h5s, h5t, h5p, h5z

Then, first time you need unistall this package using from OSgeo shell

pip uninstall h5py

For use it ,need intall it from Osgeo4W , advanced installation and install this python-h5py when restart QGIS ,try again import h5py and voilà!.
