Using Jupyter notebook in Apple M1: Error 2850 Segmentation fault

 In the live video stream by George Hotz titled, "Programming | tinygrad: neural engine on M1? | Science & Technology | Apple M1 | Part4"

He almost spent 1 hour to find out what causes the error and debugging.

He uses a number of installations, cloning repositories, debugging, installations, etc.

Here is the solution he found.

Install faulthandler as follo.

pip3 install faulthandler  

(if your python version is higher than 3.3, it is inbuilt)

The error is in the use_app_nope package.

Just comment out it. The problem solved.

For more detail, you can watch the full video.

Jupyter-notebook not running after Ubuntu upgrade

$ jupyter-notebook 

Traceback (most recent call last):

  File "/usr/local/bin/jupyter-notebook", line 7, in <module>

    from notebook.notebookapp import main

ModuleNotFoundError: No module named 'notebook'

$pip install jupyter --user installed the jupyter-note book.

But I want python3 version.
I tried to install jupyter using following command.

$ pip3 install jupyter --user

Traceback (most recent call last):

  File "/usr/local/bin/pip3", line 7, in <module>

    from pip._internal import main

ModuleNotFoundError: No module named 'pip._internal'

To solve this problem do the following.
Remove the installed jupyter using:

$sudo apt-get uninstall jupyter (and hit 'y' to confirm)

or,

$pip uninstall jupyter

and update using:

$sudo apt-get update

Now do the following:

$sudo apt-get install jupyter-notebook

Now, you can open the jupyter-notebook.

Jupyter Notebook error: AttributeError: type object 'IOLoop' has no attribute 'initialized'

AttributeError: type object 'IOLoop' has no attribute 'initialized'

This error may be due to the tornado==5.0* versions. Using Tornado 4.5.3 solves the problem.

To do this, try

pip3 uninstall tornado

pip3 install tornado==4.5.3

This solved my problem. Comment if this is useful to you.
