New M3 iMac Software Installs -- Obspy within Anaconda

For switching to Apple Silicon, the old Anaconda installation persisted after I transferred files from the old 2017-vintage iMac.  The location of the files was /Users/jjpark/opt/anaconda3, but there were also obsolete files in /Users/jjpark/anaconda3.  The New location for Anaconda files is the "shared" directory /opt/anaconda3.   The processing environments are located in /opt/anaconda3/envs.  To create these environments, I used the same commands as for the older computers

My solution is to create a new environment for the new obspy environment, and install Python 3.9 directly into it.  First, open a terminal window within Anaconda.  From the webpage:

Create a new environment within Anaconda by typing commands into the terminal window"

conda create -n obspy python=3.9

conda activate obspy

conda info --envs

assuming that you are in the obspy environment . . .

conda install -c conda-forge obspy

conda install jupyter

conda install cartopy

Note that I installed cartopy, rather than basemap.
