Running SDS on AVH-FVP

[ReinhardKeil]

I try to run the SDS-Examples\Alif\AppKit\SDS.csolution.yml with this configuration on AVH-FVP

This fails with:

What can be wrong?

I think you need a fixed version of Python v3.9 (yours is 3.13) I have installed both Python versions v3.9 and v3.13 on my PC.

[ReinhardKeil]

Installing Python v3.9 does not solve the issue.

The problem was the PYTHONPATH environment variable (set on my computer) that is used first. Removing it solved the problem. As the FVP come with a local Python39 installation, the explicit installation of Python v3.9 is not required.

However I now get a different error:

FVP_Corstone_SSE-300_Ethos-U55 -f Board/Corstone-300/fvp_config.txt -a out\DataTest\AVH-SSE-300\DebugRec\DataTest.axf

What is causing this issue?

Hi @ReinhardKeil,

The module cv2 (OpenCV) is required to run the VSI Video Server.

To use VSI Video, please ensure the following:

1. Install Python 3.9 or later on your PC.
2. Install the missing module with:

   pip install opencv-python

@jkrech is there an elegant way to get this into the FVP delivery? Having to fiddle with an old Python installation is not the best UX and conflicts with other setups.
