We are in the process of moving from Travis to GitHub Actions. For now, Travis may take a while to complete.

Hi, devs!
This is Venkatesh from India and I’m a Computer student. I have a good grip on python .I have a few things that I’d like to improve and I need to know where can I discuss. Looking forward to contribute.

phi0, phi1 = sm.symbols("phi_0 phi_1")
eta1 = 3/phi0**2 * (phi0*sm.coth(phi0) - 1)
eta2 = 3/phi1**2 * (phi1*sm.coth(phi1) - 1)
sm.nonlinsolve([3/15 - eta1/eta2,phi0 - 10*phi1], [phi0, phi1])
gives {(10ϕ1, ϕ1)}\left\{\left( 10 \phi_{1}, \ \phi_{1}\right)\right\} . But its obvious that I need the solutions. Plz help

Hello !!
I am Utkarsh Upadhyay, and I am currently a second-year Computer Science Undergraduate at IIIT Hyderabad. I want to make contributions to this organization and would love to continue contributing for GSoC 2021. I would request the mentors and experienced developers to please guide me throughout the process.
Thanks

@asmeurer
@XtremeGood it looks like a bug that it gives that
I don't know if this equation can be solved in closed form. You can try substituting phi0 for 10*phi1 in the first equation.
But even then, solve() can't solve it.
There might be a solution in terms of LambertW, but if there is, solve() doesn't know how to find it, even after rewriting the equation in terms of exp
Vishesh Mangla
@Teut2711
@asmeurer I would be happy with a numerical solution. I currently am using scipy.optimize.fsolve but I have to rewrite the equation every time. Sometimes I' m given eta and sometimes phi. With symbolic computation I could have prevented typing the expression and and given two values of phi and an eta, I could have found the eta at another fi and vice versa for two values of eta and a phi.

Hello! I was wondering if anyone could lead me to where I can learn more about Sympy objects (performing research to see if one can pry apart a SymPy object) , or it's data structure. I've looked a lot at the documentation and wiki, but there seems to be a lot of 'how-tos' and not necessarily information about the objects themselves. Thanks in advance!

@naveensaigit

@asmeurer
@XtremeGood you should probably use SymPy to compute the intermediate function and then convert it with lambdify to something you can send to fsolve
Aaron Meurer
@asmeurer
Or sympy.nsolve if you want to get a numeric solution with SymPy.

Could someone help me understand the syntax behind this test case in test_coordsysrect.py (vector module)?
I'm primarily confused by the backslash then indent

Ansh Mishra
@theanshm
the "\ " is used so that long lines of code can be continued on the next line. This is to improve readability and follow pep8 style. It allows us to open multiple files at once in the code editor without needing to scroll to read the full line of code.

Hello, I had a couple of doubts, they might seem a bit basic:
I want to import euler's constant (e) in a file in one of the modules. Can someone help me out with it?
Also, I made some changes to my clone of sympy, and i wanted to import this clone as a library and write some code with it (to test the changes). How should I proceed?
I need to use my clone as a library as I am getting an assertion error for changes made in the function, and I have no clue what is the actual output given by the new function.
Kalevi Suominen
@jksuom
From the docstring of Exp1:
    The transcendental number `e = 2.718281828\ldots` is the base of the
    natural logarithm and of the exponential function, `e = \exp(1)`.
    Sometimes called Euler's number or Napier's constant.

    Exp1 is a singleton, and can be accessed by ``S.Exp1``,
    or can be imported as ``E``.

    Examples
    ========

    >>> from sympy import exp, log, E
    >>> E is exp(1)
    True
    >>> log(E)
    1
Eva Tiwari
@evatiwari
Ok so in that file, E has been imported as the function to calculate expected value (stats module). But this gave me a hint anyway, I'll use exp(1) instead. Thanks a lot!
If someone could help me out with the second doubt, that would be great.
Ansh Mishra
@theanshm
For your second doubt you can read through Development Workflow from wiki. Basically you need to setup a virtual environment which allows you to isolate your development version of sympy from the system wide install.
Eva Tiwari
@evatiwari
Oh, I did not know that was all that was needed, I had it set up. Thanks a lot!

Hello may I seek help on an issue i face when running tests. Because sympy has a file named abc.py, it clashes with the python library and I could not run tests.
May I know how some of you overcame this?
The following is the ss of the error faced:

Does anyone know why .dict property exists only for certain discrete random variables but not for any discrete random variable?

I got the following travis CI error on one of the baseline jobs (#.5) and can't seem to figure out the issue, any hints?
"No output has been received in the last 10m0s, this potentially indicates a stalled build or something wrong with the build itself."
Aaron Meurer
@asmeurer
@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.

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?
