alt.renderers.enable("mimebundle") returns NoSuchEntryPoint

See original GitHub issue

Hi, since altair 4.0 I’ve been trying to restore inline charts in Atom/hydrogen, The docs (https://altair-viz.github.io/user_guide/display_frontends.html?highlight=hydrogen) read:

The Hydrogen project, which is built on nteract and renders Altair charts via the mimebundle renderer.

But with altair 4.1.0 trying to enable it results in the error in the subject. altair.renderers shows this list

#         "colab",
#         "default",
#         "html",
#         "json",
#         "jupyterlab",
#         "kaggle",
#         "mimetype",
#         "nteract",
#         "png",
#         "svg",
#         "zeppelin",

Tried a few to no avail. Using the nteract renderer results in this error SyntaxError: Unexpected token o in JSON at position 1 The chart displays just fine in the altair_viewer. Thanks

Ah, I see. It looks like hydrogen is expecting a JSON string, when the mimebundle contains the actual object. I would report this issue to the Hydrogen team; I don’t think Altair should be sending the serialized JSON within the mimebundle.

Problem still unchanged for me in 4.2.0.dev0 installed from master moments ago. Same repro.
