Hi @<1689446563463565312:profile|SmallTurkey79>
This call is to set an existing (already created Task's requirements). Since it was just created it waits for the automatic package detection before overriding it.
What you want is " Task.force_requirements_env_freeze " (notice Class level, that need to be called Before Task.init)

Task.force_requirements_env_freeze(requirements_file="requirements.txt")
task = Task.init(...)
