Hello, I cannot understand why it happen, but if I end a cell with a print('hello') for example and then export to html, I get error 500. Log shows:

it took me a while but at the end I figured it out: try yourself to print in a new notebook. As workaround I'm using display() or HTML() at the moment.

Strange. I'll look into it. Looks like your using Python 3.6. Are you using anaconda too?

No, virtualenv neither. I'm on Mac OS, brewed python and pip.

Edit: closing button pressed because slow reload on a touch screen ^^'

Ran into the same exact problem. Having a print statement in the code starts generating 500 errors. Also on Mac OS. No virtualenv.

@lum4chi @leeclemmer would you post the version of Jupyter and notebook your running?

pip list | grep jupyter && pip list | grep notebook should do the trick.

Looks like the 5.0 version of nbconvert changed its API. Until I get this patched you can downgrade nbconvert to 4.3.0 to get hide_code exporting to work.
pip install 'nbconvert==4.3.0' --force-reinstall

Also, what version of nbformat are you using?

nbformat 4.2.0

@lum4chi I think this is resolved with nbconvert 5.1.1. Would you upgrade and see if the issue is resolved on your end?

Hello, I can't confirmed because I've upgraded again some other packages and now hide_code toolbar nor buttons show up and another installation of the plugin cause no effect ^^'. I'm sure have some misconfiguration made by me and need time to investigate.
I'm hoping for nbextension integration :D
