Hey I am using the dolfinx/dolfinx container for executing my scripts. For a presentation I am trying to switch to the dolfinx/lab container, to give examples in a jupyter notebook. However, scripts executed in the latter do not behave like in the original container.
Is this to be expected? Is there a difference in both containers? How can i circumvent this issue? Thank you 
In the first instance check the versions,
python3 -c "import dolfinx; print(dolfinx.__version__)"
dolfinx has been in rapid development over the past months and past year, so your installations could certainly behave differently if they’ve captured different snapshots of the package.
Yes, thank you - i thought running my container with the latest tag would pull the latest image automatically - As this is not the case this explains my issue
Thank you
Is there a way to pull older images? because on the docker hub page I am only able to find the latest version of every image 
I’m not using docker myself so I’m not certain. Others will be able to clarify.
There is no back-up of older images with dolfin-x. I’ve got a few snapshots at: Docker Hub
for arbitrary days when I’ve updated my tutorial.
