Hi, I recently began trying out sympy and am running into some difficulty.
I wrote the following script, called demo.py:
import sympyfrom sympy.utilities.autowrap import ufuncifyimport sys
N = int(sys.argv[1])
theta = []
values = []for n in range(N):
theta.append(sympy.symbols('x%s' % n))
values.append(n)
summation = sum(theta)
f = ufuncify(theta, summation)print f(*values)[0]
Running it for small N, it works fine:
$ python demo.py 21
210.0
But it fails for larger N. Can anyone advise? Thanks in advance.
$ python demo.py 22
Traceback (most recent call last):
