So, I've installed the Octave Symbolic Package from here:
https://sourceforge.net/p/octave/symbolic/ci/master/tree/
In the Octave command window I typed:
pkg install -forge symbolic
After the install I ran a test (as shown in link above) by typing:
pkg load symbolic
syms x
However, I got an following error with syms x.
Symbolic pkg v2.8.0: Traceback (most recent call last):
File "<string>", line 1, in <module>
ImportError: No module named sympy
error: Python cannot import SymPy: have you installed SymPy?
Try "sympref diagnose" for more information.

Next, I visited the following site to install SymPy (which says to install Anaconda).
https://docs.sympy.org/latest/install.html#anaconda
So, then I go to the following site and download the graphical installer for macOS (Python 2.7 version).
https://www.anaconda.com/distribution/#download-section
Then I tested from the macOS terminal to see if Anaconda is installed using this command
conda --version
which returns conda 4.7.11.
I also typed
conda list
which returns (among a long list). sympy 1.4 py27_0.
So, it appears that SymPy is installed (at least at the terminal).
Next, I go back to the command line of Octave and typed:
sympref diagnose
Here is the output:
Symbolic package diagnostics
============================
Python and SymPy are needed for most features of the Symbolic package.
The Python interpreter is currently: "python".
Computers may have more than one Python interpreter installed. If you
need to, you can select a different one using the PYTHON environment
variable (see "help sympref"). For example, to use Python 3, try
setenv PYTHON python3
sympref reset
Attempting to run python -c "print(\"Python says hello\")"
status = 0
output = Python says hello
Good, Python ran correctly.
Python version
--------------
Let's check what version of Python we are calling...
Attempting to run python -c "import sys; print(sys.version)"
status = 0
output = 2.7.15 (default, Feb 5 2019, 12:31:36)
[GCC 4.2.1 Compatible Apple LLVM 8.0.0 (clang-800.0.42.1)]
SymPy Python Library
--------------------
SymPy is a Python library used by Symbolic for almost all features.
Attempting to run python -c "import sympy; print(sympy.__version__)"
Traceback (most recent call last):
File "<string>", line 1, in <module>
ImportError: No module named sympy
status = 1
output =
Unfortunately status was non-zero: probably Python cannot import sympy.
* Is there an error message above?
* Do you have SymPy installed? If not, please try to install it and
try again.
* If you do have SymPy installed, maybe it's installed for a different
Python interpreter than the one we found? Please try "setenv" as
described above to change your python interpreter.
Octave doesn't have access to SymPy.
Any idea what I did wrong?
