tab autocomplete not working

[CellAssembly]

When trying to type a command and tab to get a list to autocomplete, the kernel gets frozen on jupyter notebooks.

Does it actually freeze or just never open the tab completion?
This may be related to an issue with ipython 6 (see ipython/ipython#10493).
In the neuropixels notebooks I've added the command %config Completer.use_jedi = False to fix the issue as I've experienced it.

Never opens. But then I can't run any other cell either unless I restart the kernel.

huh, that is maybe a different issue then, but the command I posted is worth a try anyway.
