To install type pip install -U sympy
To install using anaconda:
First install anaconda using Linux Manjaro package manager.
To install latest sympy in anaconda try conda install -c anaconda sympy see
https://anaconda.org/anaconda/sympy
To update to latest conda do
sudo -i #conda update conda
To update to latest sympy do
sudo -i #conda update sympy ... now check version #python >>> import sympy >>> sympy.__version__ '1.8'
Next must install matchpy, without it Rubi will not worK:

In general, To install python package do conda install package-name to update do
conda update package for example conda update spyder
To use Rubi in sympy, do (note this no longer works in recent version of sympy. 2023)
>python Python 3.7.3 (default, Mar 27 2019, 22:11:17) [GCC 7.3.0] :: Anaconda, Inc. on linux Type "help", "copyright", "credits" or "license" for more information. >>> from sympy import * >>> from sympy.integrals.rubi.rubimain import rubi_integrate
For testing do
from sympy import * or import sympy #but now have to add sympy. to each call import os os.getcwd() os.chdir('X:\\data\\public_html\\my_notes\\CAS_integration_tests\\reports\\rubi_4_11\\code') os.getcwd() import math init_printing() init_printing(use_unicode=False, wrap_line=False, no_global=True) x = symbols('x', real=True) r=integrate(x,x) r0=latex(r) text_file = open("python.txt", "w") text_file.write("\"%s\"" % r0) text_file.close()
To check if integral failed
r=integrate(f*g, (x, L/2, L)) type(r) is integrals.Integral Out[41]: True or isinstance(r, integrals.Integral) Out[48]: True r=integrate(x,x) type(r) is integrals.Integral Out[43]: False if isinstance(r, integrals.Integral): result = 0 else: result=1
To get cwd
os.getcwd() To get list of folder in cwd do os.listdir(os.getcwd()) or ls Out[85]: ['1_Algebraic_functions', '2_Exponentials', '3_Logarithms', '4_Trig_functions', '5_Inverse_trig_functions', '6_Hyperbolic_functions', '7_Inverse_hyperbolic_functions', '8_Special_functions', 'Independent_test_suites'] f = open('Hebisch_Problems.txt','r') f.readline() f.close()
how to do timeout? simple timeouts using signal.alarm module check
http://stackoverflow.com/questions/492519/timeout-on-a-function-call for some code.
There is also talk about it here https://groups.google.com/forum/#!topic/sympy/qsPImy6WqcI
code from above is
def _timeout(self, function, timeout): def callback(x, y): signal.alarm(0) raise Skipped("Timeout") signal.signal(signal.SIGALRM, callback) signal.alarm(timeout) # Set an alarm with a given timeout function() signal.alarm(0) # Disable the alarm
elementry functions http://docs.sympy.org/latest/modules/functions/elementary.html and http://docs.sympy.org/dev/modules/functions/special.html
and http://docs.sympy.org/latest/modules/functions/index.html
Need to change
AppellF1 --> #hypergeometric function of two variables Ellipticpi--> arctanh -->atanh arctan --> atan arccosh->acosh Pi --> pi. arcsin -> asin arccos -> acos hypergeom -> hyper, arccoth -> acoth GAMMA -> uppergamma() arccsc -> acsc arcsec -> asec arccot -> acot, EllipticF -> elliptic_f EllipticE -> elliptic_e Li -> Li Si -> Si Ci -> Ci Ei -> Ei FresnelS -> fresnels FresnelC -> fresnelc
I also removed 4th field that contains integrate(...) in it as it hangs the reading of the
input file.
To run python tests do
cd /media/data/public_html/my_notes/CAS_integration_tests/reports/rubi_4_11 python sympy_main.py
To add new test, or run more tests, edit sympy_main.py and change the line
for n in range(0,1): #change the last number to the number of tests to do
To update conda and python do
conda update conda conda update python
To update sympy do
pip list | grep sympy pip install --upgrade sympy
To find version, from inside python, type
import sympy sympy.__version__
from github https://github.com/sympy/sympy/wiki/SymPy-vs.-Sage
To obtain a Rational in SymPy, one of these methods must be used: >>> from sympy import Rational >>> Rational(2, 7) 2/7
In python/sympy, to loop using index 1, can use this:
>>> for num,val in enumerate(sol,start=1): ... print("root number {} is {}".format(num,val))
For timeout in recent python, on windows, this seems to work
from subprocess import STDOUT, check_output output = check_output('dir', shell=True, stderr=STDOUT, timeout=5) print(output)
To download development sympy
sudo git clone git://github.com/sympy/sympy.git sudo git clone https://github.com/HPAC/matchpy.git
To install using conda sudo conda install multiset

To update sympy in conda do sudo conda update sympy I do not know now if I should
always use sudo for this, but it works. To check conda version do
>conda list anaconda$ # packages in environment at /opt/anaconda: # # Name Version Build Channel anaconda 5.2.0 py36_3 >sudo conda update conda [sudo] password for me: Solving environment: done # All requested packages already installed. >conda update anaconda Solving environment: done # All requested packages already installed.
Can also do conda update --all to update other conda stuff.
To get all info about conda do
