[Bug]: Displaying nwb crashes kernel

[rcpeene]

What happened?

I attempt to display an nwb file in a Jupyter notebook by simply listing the nwb to be evaluated as cell output like so nwb But this causes the kernel to crash and the nwb is not displayed.

This problem has been reported by other users of the openscope databook

Steps to Reproduce

I'm running the following notebook
https://alleninstitute.github.io/openscope_databook/basics/stream_nwb.html

except the very last line of the last cell is replaced with `nwb` rather than `print(nwb)`.
I also receive this problem in notebooks that are not streaming nwb files and are opening them locally.

Traceback

Cannot execute code, session has been disposed. Please try restarting the Kernel.
The Kernel crashed while executing code in the the current cell or a previous cell. Please review the code in the cell(s) to identify a possible cause of the failure. Click here for more info. View Jupyter log for further details.

Hi @rcpeene, thanks for submitting an issue, could you try installing pynwb>=2.6.0 and then running the stream_nwb notebook again with nwb instead of print(nwb) in the last cell?

I think this issue is related to this recursion error that was fixed in pynwb versions 2.6.0 and later. Upgrading pynwb allows the nwb html representation to be displayed when I run the stream_nwb notebook locally. But I'm not positive if that error is what's causing the kernel to crash in your case.

Great this worked!
