Hangs in Jupyter Notebook on Mac Mini M1

[ard9000]

It hangs before the first loop. Same notebook works fine on Intel macs.

Output from command line:

[IPKernelApp] ERROR | Exception in message handler:

Can confirm having the same problem, but I am running an Intel Thinkpad with Linux (Kernel 5.13.9). Not sure that this bug is hardware related though

[TheTechRobo]

I don't think it's hardware related. Are you using another environment such as JupyterLab?

[codecrap]

I have tested it on jupyter notebook, jupyter lab and inside Pycharm Professional's (2021.3) notebook viewer, all having the same problem. All using python 3.8.8, output of jupyter --version:

jupyter core     : 4.7.1
jupyter-notebook : 6.4.0
qtconsole        : 5.1.1
ipython          : 7.23.1
ipykernel        : 6.4.1
jupyter client   : 6.1.12
jupyter lab      : 3.2.3
nbconvert        : 6.0.7
ipywidgets       : 7.6.5
nbformat         : 5.1.3
traitlets        : 5.0.5

Hello, Yeah, this doesn't seem related to hardware. This is a normal Python error: https://docs.python.org/3/library/os.html#os.get_terminal_size But I can't understand why it wouldn't be connected to a terminal...

Does it work on a normal cell?

import os
os.get_terminal_size()

This is going to be fixed today, in #129!
