VOT 2023 error

[imadtoubal]

Hi, I have been trying to follow these instructions to download the VOT2023. But it seems there might be an error with the package?

Below is the full error stack.

$ vot initialize vots2023
A newer version of the VOT toolkit is available (0.6.1), please update.

The vots2023 stack is not available yet. We expect to be released with the toolkit version 0.6.1 in the next days. You can test the toolkit and tracker integration with the development dataset (using the command: vot initialize tests/multiobject)

Does the 'vot initailize vots2023' can be processed successfully? The test dataset can not downloaded right now.

This issue is now outdated as the new stack is available in recent versions.
