Re: [sympy] Re: SymPy 1.11rc1 released
Hi Peter, I think that there might need to be a second release candidate after fixing this: https://github.com/sympy/sympy/issues/23924 Internally lambdify with modules='scipy' uses "from scipy import *" to create a namespace for executing the generated code. However in the next release of scipy it might be that "from scipy import *" will raise ImportError: https://github.com/scipy/scipy/pull/15607#issuecomment-1215110575 The lambdify code catches the ImportError but then fails to find the functions that it expected to find by importing them from scipy. I think it's important for SymPy to have a fix for this before the next release of SciPy. The lambdify code that does this already needed to be changed because it shouldn't be using functions like scipy.sin etc that are really aliases for numpy functions and are now deprecated. I just didn't want to try and fix that myself because I don't know the lambdify code so well. Also changing something like this right before release is generally something I would prefer not to do because it leaves minimal time for testing.

Re: [sympy] Re: SymPy 1.11rc1 released
Dear Oscar, I guess, you will inform us when the 'final' version is released. I understood from Jason Moore that there is some improvement relating to 'lambdify' which I want to try as soon as possible. NB: I play around with sympy.physics.mechanics mostly, just for fun, nothing serious, just what semi retired engineers do. :-)) Thanks, Peter On Sat 13.
