importError：DLL加载失败（导入h5py）

Question

我安装了OSGeo4W软件包，以便在Windows环境中使用h5py。

我使用OSGeo shell使用pip install安装h5py。

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

当我打开QGIS并转到QGIS中的Python控制台时，我收到此错误：

import h5py
Traceback (most recent call last):
File "", line 1, in

我不知道如何在QGIS python控制台中使用h5py

Answer 1

检查这个https://github.com/h5py/h5py/issues/828。如果你安装使用

点击安装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
  File "C:/OSGEO4~1/apps/qgis/./python\qgis\utils.py", line 607, in _import
    mod = _builtin_import(name, globals, locals, fromlist, level)
  File "h5py\h5p.pxd", line 16, in init h5py.h5a (D:\Build\h5py\h5py-2.7.0\h5py\h5a.c:6968)
  File "C:/OSGEO4~1/apps/qgis/./python\qgis\utils.py", line 607, in _import
    mod = _builtin_import(name, globals, locals, fromlist, level)
ImportError: DLL load failed: No se encontró el proceso especificado.

然后，第一次需要从OSgeo shell中取消使用此包

点击卸载h5py

使用它，需要从Osgeo4W安装，高级安装并在重启QGIS时安装此python-h5py，再试一次import h5py和voilà！。
