Is there a way to compute the gradient and hessian matrices of a vector
field like u = (x) i + (2yz) j + (3xy) k.

Hi Volker,
The problem is that you are using sympy.numbers.Zero. There is no
sympy.numbers module. Rather there is a sympy.core.numbers module
which is where Zero is defined. In SymPy 1.5 the main
sympy/__init__.py used to do
from .core import *
which resulted in the sympy.core.numbers module
Hello,
I have library that is organized as follows:
mymod/__init__.py:
from .base import *
mymod/base.py:
import sympy
from .modA import *
from .modB import *
mymod/modA.py:
from .base import *
var = sympy.numbers.Zero
mymod/modB.py:
from .base import *
# other code
When I run python -c
