Hi, I am trying to start a Docker container (skifter90/swissparl-topic-tagger:latest) on Renku. It works on my local machine, but on Renku it the Session reaches stage 3 and is stuck there and never finishes loading. The error that the administrator of RenkuLab reported to me is “/bin/sh: 1: python: not found”. Did anyone experience a similar issue a knows how to fix it? Renku itself does not provide more insightful logs. Best, ---

Hi @kapllan , Thank you for posting your issue here. Is there any reason why you need to create your own Docker image? We usually recommend to use code based environments as explained [here](https://docs.renkulab.io/en/latest/docs/users/sessions/guides/environments/create-environment-with-custom-packages-installed). ---

Hi @elisabetc thank you for your response and sorry for my late reply. The reason why I would like to do it with a Docker image directly, is because I am using this library [GitHub - tomtung/omikuji: An efficient implementation of Partitioned Label Trees & its variations for extreme multi-label classification · GitHub](https://github.com/tomtung/omikuji). It is built on Rust and just has a Python wrapper which makes it somehow difficult to install. I can do it in a Linux environment, but as far as I can see Renku allows to decide between Python and R. The Linux Desktop does not seem to be a good solution. I was able to install it in the Docker image. Since Renku offers deployment via Docker Images I thought I should try it that way. Best ---

@elisabetc Ok, I think I found a way to solve this issue. I will do it your way. It seems to work. Thank you! ---

Hi @kapllan , I totally understand. Does your Docker image have a front end? As of now, you need to have a front end as explained in the [documentation](https://docs.renkulab.io/en/latest/docs/users/sessions/guides/environments/use-your-own-docker-image-for-renku-session#what-docker-images-can-i-use-in-renkulab-sessions). ---

Great! Happy to hear that you could find out a way to make it work.
