importError: DLL加载失败(导入h5py)

Question

我安装了OSGeo4W包，以便在Windows环境中使用h5py。

我使用OSGeo shell使用安装h5py。

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

当我打开QGIS并进入QGIS中的Python控制台时，会得到以下错误：

​

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

我不知道如何在QGIS控制台中使用h5py

Answer 1

看看这个https://github.com/h5py/h5py/issues/828。如果您安装使用

pip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，当您第一次需要从OSgeo shell中使用这个包时

pip卸载h5py

要使用它，需要从Osgeo4W获得intall，高级安装，重新启动QGIS时安装该python-h5py，再试import h5py和voilà！
