在这种情况下,使用numpy.seterr

i designed a simple function to return a mathematical function which can be used to fit experimental data to it. The functions looks pretty much like the following:
def colecole_2(f,*p):
term1=p[0] * ( 1 - 1 / (1 + numpy.power((0+1j) * 2 * numpy.pi * f * p[1], p[2])))
term2=p[3] * ( 1 - 1 / (1 + numpy.power((0+1j) * 2 * numpy.pi * f * p[4], p[5])))
return p[6]*(1-abs( term1+ term2))
Unfortunately I run into troubles with RunTimeWarnings as:
RuntimeWarning: overflow encountered in power
RuntimeWarning: overflow encountered in divide
due to values that are too large or small. I am not able to figure this problem out on my own though. Is there any way to redefine my function so it will pass without warnings?
Use numpy.seterr
