Hi! For now, the best officially available solution is to build your dependencies into the image you’re using.
In the near future, the preferred way to do this will be via a feature called runtime environments
An experimental version of this functionality exists in Ray 1.4.0 but is not yet documented.
I recommend bugging the maintainers of runtime envs on this thread: Dependency management with ray for remote task execution - #3 by asm582
