Dear all,
I am developing a Qgis python plugin using PyTables 2.4. There is an error when
starting Qgis main application. I checked the error message and found that
there is an error when call 'import tables' because some dll cannot be loaded.
But when I run the python not in Qgis environment, PyTables works correctly.
I also open the Qgis console window and input 'import tables'. The error
message is the same, saying that some dll cannot be loaded.
when I start Qgis with my own Python plugin, the error message is as following:
Couldn't load plugin UAV due an error when calling its classFactory() method
Traceback (most recent call last):

ImportError: DLL load failed: The specified procedure could not be found.
I have reinstall the pytable and also try the version 2.3, 2.2 and 2.1. I also
add the tables package path to the system 'path' environment variable. The
errors are still the same. PyTables works correctly in standard python
environment, but failed in Qgis python environment.
I am not familiar with Qgis embedded python.Could any one help me on this.
