Unable to use numpy python module with DIAdem python data plugin.

[LDobbins]

I am unable to use a python data plugin that makes use of the numpy python module. When attempting to "Load Data" from the desired file, I am met with an error "Module cannot be loaded from compiled python script:" I have pip installed numpy but it is still unable to load the appropriate module. Has anyone figured a workaround for this? Or is it not possible to use the numpy module?

Hello LDobbins,

The pip included modules are problematic when running in parallel in an embedded environment and the distribution of a DataPlugin via *.uri file is limited to only 1 file. Python DataPlugins consist of only one Python file that contains all the logic. 

​We recommend creating your Python DataPlugins with ONLY the functionality available in the plain Python 3.5 execution engine.

When you say that it is problematic whilst running in an embedded environment, does this mean that should I point DIAdem to a different installation of python rather than its embedded version, numpy and other python modules would be useable?

No, currenly you must use the embedded Python 3.5 version.

Ah, that is a shame. Thank you very much for your time!
