Hi, is there a way to change/configure the Python venv that a whole pipeline and individual solids are run under?

not currently (from dagit at least) - how are you starting these executions? if you use the python APIs or dagster / dagster-graphql CLIs you could execute a pipeline from within the specififc venv

could write a run launcher that did this

I am currently launching the executions from within dagit. I am looking for a way to enable folk to work on different development streams of the same job, so launch in different venvs. I guess, it could be done via API, but then we lose all the benefits of the UI.

makes sense - this is something we expect to make easier / possible in the future but haven’t quite reached yet. It would be possible to write a custom

RunLauncher

and add it to your instance and that run launcher could use a

tag

on the pipeline to choose a venv to use to execute

dagster-graphql

in to satisfy the execution request
