I tried to follow this doc to launch jupyter in my Mac, but it did not work. Could anyone help? 

Ties-MBP:10studio-4 chengtie$ pip --version
pip 19.0.1 from /Library/Python/2.7/site-packages/pip (python 2.7)

Ties-MBP:10studio-4 chengtie$ jupyter --version
4.4.0

Ties-MBP:10studio-4 chengtie$ pip install notebook
DEPRECATION: Python 2.7 will reach the end of its life on January 1st, 2020. Please upgrade your Python as Python 2.7 won't be maintained after that date. A future version of pip will drop support for Python 2.7.

You are using pip version 19.0.1, however version 20.0.2 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.

    As you can see from the messages, your computer has Python and pip but that is woefully outdated because Apple only really meant it to be used for the system. You'll need Python 3 and you'll have an easier time of it using conda or a venv (or both) to isolate and manage this. See [here](https://janakiev.com/blog/jupyter-virtual-envs/) , [here](https://towardsdatascience.com/getting-started-with-python-environments-using-conda-32e9f2779307), and [here](https://stackoverflow.com/a/58068850/8508004). – Wayne Mar 17 '20 at 16:01

I finally installed first conda, then did conda install -c conda-forge notebook.
