Yes, it looks like a fairly new version, too. Does just import IPython help?
I doubt this will make much difference but since looking at https://aws.amazon.com/blogs/big-data/install-python-libraries-on-a-running-cluster-with-emr-notebooks/ there are some differences in the environments, have you tried without the .core part? I put some examples with just IPython.display here?
Also you didn’t say if you are using the classic interface or the JupyterLab interface. If using JupyterLab, I suggest switching to the classic interface or vice-versa and see what happens? If you can. I don’t know how universal the ability to switch I discuss in the middle paragraph here . This usually fixes widgets that often show up as these <object> tags in JupyterLab.
