The shell path for a user in macOS or OSX is a set of locations in the filing system whereby the user has permissions to use certain applications, commands and programs without the need to specify the full path to that command or program in the Terminal. This will work in macOS Mojave, Sierra and all older OSX operating systems; El Capitan. This path varies according to which operating system version and which Anaconda version you use, so you will need to search your file system to find the correct path to your Python interpreter. You can search for the Python interpreter with your operating system’s file manager, such as File Explorer on Windows, Finder on macOS, or Nautilus on. Change Jupyter Notebook startup folder (Mac OS)¶ To launch Jupyter Notebook App: Click on spotlight, type terminal to open a terminal window. Enter the startup folder by typing cd /somefoldername. Type jupyter notebook to launch the Jupyter Notebook App The notebook interface will appear in a new browser window or tab. So an obvious potential candidate is Jupyter (nee IPython), but it has no support for musical notation out of the box. But it is doable and in this post I'll walk through how I got it to work on my Mac. This is also my first attempt at using a Jupyter notebook as my blog post in Nikola so I'm kiling two birds with one stone.
This page provides the instructions for how to install and run IPython and Jupyter Notebook in a virtualenv on Mac.
Most probably your Mac has already come with Python installed (see step 1 and step 2 below to check whether Python and Python 3 is installed on your mac, because my Mac book air has both Python and Python3.6 installed, I will go ahead to step 3 to install virtualenv).
Open a terminal on your mac and type in Python and Python3 to see whether Python and Python3 installed on your mac. See below for example.
Follow the steps below for detailed instructions.
Step 1: Check whether Python is installed on your Mac
To test whether your Mac has Python 2.x or 3.x, look at the instructions below.
Open a terminal (in your launchpad, type in terminal, and then click and open it.)
Type inpython, if you see similar thing as the pic shown below, it means python 2.7 was installed on your Mac
typeexit()to exit from the Python 2.7 environment
Typepython3in your terminal, if you see similar warning as the pic shown below, it means you will need to install Python 3 (see the steps below for installation). If you see older version (< 3.5) of python 3 installed on your mac, follow step 2 to install Python 3.5
Step 2: Install Python 3.5
I recommend you download Python 3.5.4 from here, if you do not have Python 3.x pre-installed on your mac.
Click the installer and install it following the wizard.
When you finish the installation, typepython3in your terminal, if you see similar stuff in the pic below, Python 3.5 is installed successfully and you are ready to proceed to step 3.
Step 3: Install virtualenv
Note:the command text in blue is the exact command you should type into your terminal, the same through this whole instruction.
Step 4: Setup virtualenv environment
Issue the command below to set up a virtualenv environment that we will use later, using thevitualenvwe installed in step 3 above.
Step 5: Install IPython
Before installing IPython and Jupyter Notebook, be sure to activate your python virtual environment first.
Type the following command to install IPython
Step 6: Install Jupyter Notebook
Use the following command to install Jupyter Notebook
Step 7: Test jupypter notebook installation
Step 8: Add Kernel
The Jupyter Notebook and other frontends automatically ensure that the IPython kernel is available. However, if you want to use a kernel with a different version of Python, or in a virtualenv environment, you’ll need to install that manually.
We are using virutalenv, so we need to installIPythonkernel in the virtualenv we created in Step 4 above.
Step 9:Before we are running our jupyter Notebook, let us create a folder from which we will start our jupyter notebook.
The following command will change our directory to Desktop (cdrefers to change directory)
the following command will help us create a folder named Geog597_ML_session under our Desktop folder
the following command will change our directory into the folder we just created.
Step 10: Run Jupyter Notebook
Then your default browser should automatically open a web page similar to the one shown below.
If the web page does not show up automatically, just type localhost:8888 into your browser, you should see the page shown above.
Step 11: Testing and Using Jupyter Notebook
By this point you should have Jupyter Notebook running, and you should be connected to it using a web browser. Jupyter Notebook is very powerful and has many features. Below I will outline a few of the basic features to get you started using the notebook. Automatically, Jupyter Notebook will show all of the files and folders in the directory it is run from (for our case, it is empty now, because we have not put anything in that folder Desktop/test_jupyterwe just created in step 9 ).
To create a new notebook file, select New > ipy-jupyter-venv3 from the top right pull-down menu (Note: this is the so called kernel we installed in Step 8 above):

This will open a notebook. We can now run Python code in the cell or change the cell to markdown (markdown is for note, not for code). For example, change the first cell to accept Markdown by clicking Cell > Cell Type > Markdown from the top navigation bar, or by click the Markdown shown in the pic below. We can now write notes using Markdown, for example, type the following into the cell after changing it to markdown:
HitCtrl + Enter, you will see it the text changed into heading style.
Then insert one cell by the menu shown below (insert Cell Below).
type in the following
and then hitCtrl + Enter. You should see the following.
Step 12: Stop jupyter Notebook.
To stop the Jupyter Notebook process, pressCTRL+C,
typeY, and hitENTERto confirm. The following will be displayed:
Step 13: Exit virtualenv environment
Once you are done, remember to exit your virtualenv using the following command:

Step 14: Instructions for using Jupyter Notebook next time
Next time when you need to use you jupyther notebook, following the steps summarized below.
