“module”对象没有属性“iirnotch”

Question

“module”对象没有属性“iirnotch” 我已经安装了最新的scipy 0.19，但是scipy文档显示他们添加了这个函数 https://docs.scipy.org/doc/scipy/reference/generated/scipy.signal.iirnotch.html

from scipy import signal 
fs = 50000 # Sample frequency (Hz)
f0 = 50.0  # Frequency to be removed from signal (Hz)
Q = 30.0  # Quality factor
w0 = f0/(fs/2)  # Normalized Frequency
# Design notch filter
b, a = signal.iirnotch(w0, Q)

Answer 1

scipy的版本应该是0.19.1。如果没有，请尝试升级scipy和numpy。在
