No matter what Python approach I take to reading a file on the MacBook Pro desktop, I get a 'path does not exist' error message. In Terminal, I find that a web of directories was created where Jupyter Notebook has a CWD on directory /home. Nothing in this network is visible on the Finder. In Terminal, I did a cp file-on-desktop same-file-in-home-directory. I got error message that the /home directory path didn't exist. The computer is acting like the Jupyter Notebook created a disk partition. It can be seen in Terminal, but it isn't recognized by Finder or anything else in the Macos file management. What do I do so that I can read/write twix a Jupyter Notebook and my MacBook Pro?
