New issue 2015 by ggventurini: Hangs attempting to solve a system of linear
equations
http://code.google.com/p/sympy/issues/detail?id=2015
I often have this issue. This is one of the way I can reproduce it.
I can't solve this problem for a, b, c, f, h, k, n:
b + r/d - c/d = 0
c*(1/d + 1/e + 1/g) - f/g - r/d = 0
f*(1/g + 1/i + 1/j) - c/g - h/i = 0
h*(1/i + 1/l + 1/m) - f/i - k/m = 0
k*(1/m + 1/o + 1/p) - h/m - n/p = 0
n*(1/p + 1/q) - k/p = 0
Python snippet, the pickle file is attached:
import sympy
import pickle
fp = open("bugreport.pickle")
[eq, x]= pickle.load(fp)
sympy.solve(eq, x)
[... program hangs...]
