cling does not support Jupyter+Tornado>=5.x #236

Closed jhgoebbert closed 6 years ago

jhgoebbert commented 6 years ago

Hi,

it seems as if the cling Jupyter-kernel does not support Jupyter, which is based on Tornado>=5.x: [...] instance must be a ZMQIOLoop, but a value of class 'tornado.platform.asyncio.AsyncIOMainLoop' [...]

Thank you for the great compiler! Best, Jens Henrik

Hi Jens,

I think that's not a cling issue but a general jupyter notebook dependency issue. See e.g. https://github.com/conda-forge/notebook-feedstock/issues/31

Looks to me like Jupyter 5.3.0+ contains the fix: https://github.com/jupyter/notebook/pull/3034

Hi Axel,

I rebuild all dependencies with GCC 5.5.0 again and it works fine now. Sorry for the wrong interpretation of the error message and thanks a lot for the good hint !!

Best, Jens Henrik
