Caution

We are fixing the problem in inference 0.28.2, but it is not possible to be fixed older releases - for those who need to fix that
in their environments, please modify the build such that installing inference you also install tokenizers<=0.20.3.

pip install inference "tokenizers<=0.20.3"

🔧 Fixed issue with CUDA and stream management API

While running inference server and using stream management API to run Workflows against video inside docker container, it was not possible to use CUDA due to bug present from the very start of the feature. We are fixing it now.
