我目前正在Sympy帮助我进行数学计算.现在,我正在尝试执行数值集成,但是在我运行脚本的任何时候都会出现错误.这是脚本:

from sympy import *
cst = { 'qe':1.60217646*10**-19, 'm0':N(1.25663706*10**-6) }

d = 3.6*10**-2
l = 20.3*10**-2
n = 217.0
I = 10.2

# Circum of loops
circ = l/n;
# Radius
r = N( circ/(2*pi) )
# Flux through a ring a distance R from the ceter
def flux(rad, I, loopRad):
    distFromWire = loopRad - rad
    bPoint = cst['m0']*I/(2*pi*distFromWire)
    return ( bPoint*2*pi*rad )

# Integrate from r=0 to r=wireRad
x = Symbol('x')
ig = Symbol('ig')
ig = …
