调用 scipy function 时出现属性错误

Question

I am trying to run the following function defined on a separate python file using jupyter notebook

def f(x):
    return 2 * norm.cdf(x)

AttributeError: 'function' object has no attribute 'cdf'

However, I am getting an Attribute error. I am not sure what is exactly going on as I imported the module correctly in the.py file.

Answer 1

There are plenty of norm() s in the sea, so your problem is very likely that you are not calling the norm() that you think you are. It is always good to be verbose:)

import scipy as scp
from scipy import stats

def f(x):
    return 2*scp.stats.norm.cdf(x)
