Can't run Jupiter Notebook on Mac m1

Question

Just reinstalled Anaconda on my Mac m1, and now when I try and open Jupyter Notebook using the command line, it gives me this error:

jupyter notebook
Traceback (most recent call last):
  File "/Users/alborzgharabaghi/opt/anaconda3/bin/jupyter-notebook", line 7, in <module>
    from notebook.notebookapp import main

    /Users/alborzgharabaghi/.local/lib/python3.8/site-packages/zmq/libzmq.cpython-38-darwin.so: mach-o, but wrong architecture

Any help would be appreciated.

Answer 1

The problem is coming from the pyzmq library!

Its non-M1 compatible version has probably been installed on your Mac. You will need to reinstall it with a Rosetta Terminal.

Step 1: create a new Rosetta terminal, follow that tuto (or any other on the web)

Step 2: open your new Rosetta terminal and re-install pyzmq :

pip uninstall pyzmq
pip install pyzmq

Answer 2

I've been experiencing similar issues with this and other CLI commands with the M1. MacOS ships with an old version of Bash, updating Bash to v5 (and making sure I'm running commands in that environment) cleared up this error for me. This article helped: Upgrading Bash on MacOS
