VOT Initialization

Dear team,

I'm trying to initialize vot but kept getting this error:

ImportError: Could not load libtrax.

Can you assist please.

This looks like an installation problem, if the toolkit is installed using pip then it should automatically install dependencies correctly. Since trax is installed as a python package it may be that the native library was not compiled (error during installation).

The toolkit is already installed using pip. However, I tried to install an older version of the toolkit (pip install "vot-toolkit==0.5.3") with  (pip install "vot-trax==3.0.3") and it's working fine.

So far I have not noticed problems with this elsewhere (toolkit installation on several machines). Is there anything unusual printed during pip install? Another problem may be Windows, I will check it there when I get a chance since I am not using Windows myself.
