SymPy Deprecation

Hi,
very nice platform for spectral methods.
I have just installed following the instructions for conda and I found that Sympy gives a warning from

shenfun/lib/python3.9/site-packages/sympy/utilities/lambdify.py:807: SymPyDeprecationWarning:

The list of arguments is a set. This leads to unpredictable results
has been deprecated since SymPy 1.6.3. Use : Convert set into list or
tuple instead. See sympy/sympy#20013 for
more info.

for some demos (dirichlet_poisson2D, dirichlet_poisson3D, dirichlet_Helmholtz2D), but I did all the demos.

Best,
Alberto

Thanks Alberto,

I have Sympy 1.6.2 on my machine, so I've never seen the warning before. But I know what it's about, and it's easy to fix.

I actually also ran the pytest and there are a lot of warning about the use of np.float or np.complex, but I did not look in details into it. I guess they are all connected with the latest versions of numpy, sympy, ... I am going to run the test properly and I will let you know. Alberto
