I forgot to mention that to install this release you can use:

pip install --pre sympy

Oscar,

When I use this command, I get this:

Requirement already satisfied: sympy in
c:\pythonsystem\lib\site-packages (1.10)
Requirement already satisfied: mpmath>=0.19 in
c:\pythonsystem\lib\site-packages (from sympy) (1.1.0)
WARNING: You are using pip version 21.0.1; however, version 22.2.2 is
available.
You should consider upgrading via the 'c:\pythonsystem\python.exe -m pip
install --upgrade pip' command.


Is it just that my pip is out of date?

If you already have sympy installed and are trying to install the
prerelease then you need to either first uninstall sympy or otherwise
tell pip that you want to upgrade:

pip install --upgrade --pre sympy

Thanks Oscar!

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

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.

Oscar

It looks like SciPy is going to fix this upstream https://github.com/scipy/scipy/pull/16854.

I think that's already been an issue in the current release https://github.com/sympy/sympy/issues/20294#issuecomment-921294268. So I don't think it needs to be a release blocking issue.
