Based on the SDK python-samples, i could successfully build and run a AMD64 snap in the ctrlX Virtual and even in AMD64 based X7 ctrlX CORE.
But the ARM64 snap built successfully, is not able to run in the X3 ctrlX CORE. It looks like the python dependencies are not getting linked / loaded properly. Could not able to figure out, how the normal build script in SDK, which works for AMD64 snap, is not working for ARM64 snap.
It is the same issue even for simple 'hello world' kind of ARM64 snap with python dependents (like Numy etc.)
Currently i have issues with loading Numpy, which later i will be adding other python dependents.
