Problem using SymPy

Hi everybody, I am new to Julia and I would like to use the sympy functionalities.
I have Julia 1.8 installed on Mac OS, with python 3.
The SymPy package throws the error below.
Any clue?
Thanks
Joe

Does something like this work?

julia> using PyCall

julia> sympy = PyCall.pyimport_conda("sympy", "sympy")
PyObject <module 'sympy' from '/Users/verzani/.julia/conda/3/lib/python3.7/site-packages/sympy/__init__.py'>

julia> sympy.pi
PyObject pi

Hi, thanks for your reply. Unfortunately, it does not work:

**julia>** using PyCall

**julia>** sympy = PyCall.pyimport_conda("sympy", "sympy")

PyObject <module 'sympy' (<_frozen_importlib_external._NamespaceLoader object at 0x136533970>)>

**julia>** sympy.pi

**ERROR:** KeyError: key :pi not found

Stacktrace:

[1] **__getproperty**

@ ~/.julia/packages/PyCall/twYvK/src/PyCall.jl:313 [inlined]

[2] **getproperty(**o::PyObject, s::Symbol**)**

[3] top-level scope

**julia>**

Edt: could it possibly be a clash between homebrew python and conda python?

anything is possible!
