Python wrapper works in virtual environment, but not with PyCharm

[yrzhanov]

I needed to debug one of the python wrappers that use C++ compiled dll from VoxelSDK. Running the program from virtual environment works:

(py27) D:\VariousCodes\VoxelSDK-Calibration\calibwizard>python VxlToPng.py
WARNING: CameraSystem: Failed to load or register a depth camera factory from library ti3dtof.dll. Ignoring this library.
WARNING: CameraSystem: Failed to load or register a depth camera factory from library voxel.dll. Ignoring this library.

cols=320 # added by me
rows=240 # added by me
Saved vxls/tintincdk_example_190cm.png # added by me

It gives only warnings. Here, I copied Voxel.py (SWIG-generated), Voxel.pyc, _Voxel.pyd, voxel.dll locally (to avoid confusion).

Then created project for PyCharm and copied all these files to venv folder – the GUI is showing them. Running script fails though:

The exit code hints that there is a clash between x86 and x64 architectures. but everything is compiled on Windows 10, x64
Looks like local voxel.dll is being looked at, and ignored. Then it complains about ti3dtof.dll (which is ignored in the first case).
