Dear Aaron,
Thanks! YES, I installed sympy from anaconda. But when I installed gmpy2 yesterday, I did not get a message like ‘exists already in the environment’ or similar. (I know nothing about anaconda, just follow the installation instructions given to me by my son) Thanks!

If you use conda-forge chances are you've already been using it this whole time.

I installed it (I used anaconda, rather than pip), all went well. As you predicted, I did not find any difference so far, will keep on observing. Thanks again!

It is very easy to install gmpy2 (pip install gmpy2) to see if it does speed anything up. I don't think that the mechanics module explicitly uses any of the low-level polynomial code so the question would be whether something like cancel or factor is being used somewhere. My expectation is that things like that would be avoided in mechanics. The next post will talk about matrices which is more relevant for the mechanics module although the matrices would be matrices of polynomials so having fast polynomials also makes a big difference to linear algebra. This would be very relevant to our previous discussion here: https://github.com/sympy/sympy/issues/24679 -- Oscar -- You received this message because you are subscribed to the Google Groups "sympy" group.
