👋 remote tasks are ran using the default flytekit docker image unless you specify otherwise. And, that one doesn't have the package you referenced installed (
Dockerfile here, I believe).
I suspect you just need to build a custom docker image & configure your tasks to use that (there is also an imagespec feature that might save you some time).
The entire customization process is a little involved, but not too bad once you've ran through it. The
getting started docs provide a good intro.
