pip install rasa[convert] solves the problem on my local dev machine, but how do I add the dependency to the helm chart?

I tried:

  initFile: |-
    pip install rasa[convert]

In values.yaml but that didn’t work.

For now I solved the problem by building my own image like this:

diff --git a/Dockerfile b/Dockerfile
index 936c3bd0718..f01a2507d45 100644
--- a/Dockerfile
+++ b/Dockerfile

   poetry build -f wheel -n && 
   pip install --no-deps dist/*.whl && 
   rm -rf dist *.egg-info

Then I built the image with docker build . -t cck197/rasa:rasa-1.9.5 and pushed it docker push cck197/rasa:rasa-1.9.5 then in values.yaml:

 rasa:
   # name of the Rasa image to use

+  name: "cck197/rasa"
   # tag refers to the Rasa image tag
-  tag: "1.9.5"  # Please check the README to see all locations which have to be updated for a rasa release)
+  tag: "rasa-1.9.5"
