I was waiting for my class today to send you the result of sympref diagnose:
Symbolic package diagnostics
Python and SymPy are needed for most features of the Symbolic package.
The Python interpreter is currently: “python3”.
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 2, try
setenv PYTHON python2
Attempting to run python3 -c “print(“Python says hello”)”
status = 0
output = Python says hello
Good, Python ran correctly.
Let’s check what version of Python we are calling…
Attempting to run python3 -c “import sys; print(sys.version)”
status = 0
output = 3.9.1 (default, Jan 14 2021, 01:19:30)
[Clang 11.0.0 (clang-1126.96.36.199)]
SymPy Python Library
SymPy is a Python library used by Symbolic for almost all features.
Attempting to run python3 -c “import sympy; print(sympy.version)”
Traceback (most recent call last):
File “”, line 1, in
ModuleNotFoundError: No module named ‘sympy’
status = 1
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
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.
And this time in “text”!
