@AlexCQY make sure you aren't inside of the sympy library directory when running the tests
it shouldn't be able to import abc.py as a top-level module, only as sympy.abc or .abc as a relative import.

@kirk86

@kirk86 I'm not sure if it would answer your question, but I have tried dealing with it in #20554 .

@evatiwari Thanks!

What does the test result "E" indicate? It is not listed on the tests page in the wiki, is this intended or does that page need to be updated?

I would love to contribute to sympy

You can go through https://github.com/sympy/sympy/wiki/Introduction-to-contributing for starters and then you can refer to the docs https://docs.sympy.org/latest/index.html.

Hello everyone, Can someone please guide me on how to test changes one makes to the codebase. Like if I change a particular code locally then how can I check whether my changes are admissible or not.

You should go through https://github.com/sympy/sympy/wiki/Development-workflow, it will resolve your doubts.

is it possible with sympy to get the formula of sin(x) instead of the resulting value, I did not found that in the documentation
is this done by a solver?

sorry for asking, I found it

@KarlJoad
I am trying to figure out a problem in octsympy. In sympy 1.5.1, sympy.compatibility.integer_types gives a tuple of the types of integers supported (<type> int and long). I can't find an equivalent option in sympy 1.6.2. Where is it located? I've checked sympy.core.compatibility, but there doesn't seem to be one there that has both the types int and long, just the int class.
Aaron Meurer
@asmeurer
This was removed because it's no longer needed, as SymPy no longer supports Python 2.
Karl H
@KarlJoad
Ok... So, can cases of sympy.compatibility.integer_types be replaced with Python 3's built-in int clas?
Aaron Meurer
@asmeurer
Yes
Also FWIW sympy.core.compatibility is only designed for internal use in SymPy, so using it in an external library is not recommended. We don't make any backwards compatibility guarantees for that module.
Karl H
@KarlJoad

Ok, I'll do that then, and hopefully it works.

Ok. I'm not the core maintainer, so I don't have any control over that.

Oh, I assume the same holds true for sympy.compatibility.string_types and python 3's str class, correct?
Aaron Meurer
@asmeurer
Yes

Hiya, I'm about to submit a PR for cupy support on top of #20271
Just a quick question: The numeric computation docs mention Theano support, but I was unable to get that to work. Does it currently work?
Thomas Aarholt
@thomasaarholt
Scratch that, a quick search among the GH repo issues shows that it should work fine. I wonder where I went wrong!

@thomasaarholt
Hiya. Given func = sp.lambdify(args, expr), is it possible to print the "string" that lambdify compiles, ie. the expression that is eventually called by numpy (or mpmath)?
Aaron Meurer
@asmeurer
@thomasaarholt yes, you can look at inspect.getsource(func), or just func?? in ipython

"Does anyone know how to give sympy known identies to help it with tricky integrals? I'm doing an integral across all space for a bessel function and I have a neat identity which I think would help sympy to solve it."
The manual integrate module was suggested but the identity I have is for a definite integral
And I don't think manual integrate works with definite integral rules?
Eva Tiwari
@evatiwari
I have a doubt which is not exactly SymPy related, but it might help me out with an issue. What is the difference between tensor product of two matrices and two bras/kets? Why is it that the dagger of one does not change the order, while that of the other does?
Eva Tiwari
@evatiwari
@ctr26 could you open an issue for the same? There is a function called heurisch(), which deals with Bessel functions, but it is only for indefinite integrals and is based off of a slow algorithm. I did not find any option which is as good as manual integrate (which, you are right, does not work with rules for definite integrals).
Craig Russell
@ctr26
Have done thanks
What does it mean when heurisch never returns an output?
Eva Tiwari
@evatiwari
@ctr26 it hangs, on interrupting the process it shows the traceback.
