当我使用 sp.integrate.quad() 时,将 scipy 作为 sp 导入时出错
Error importing scipy as sp when I use sp.integrate.quad()
我在将 scipy
导入 Python 时遇到错误。当我写:
import scipy as sp
x2 = lambda x: x**2
print sp.integrate.quad(x2, 0, 4)
我收到错误:
sp.integrate.quad: "NameError: name 'integrate' is not defined".
为什么会出现此错误?
导入scipy
不会自动加载integrate
子包。使用:
from scipy.integrate import quad
或
import scipy.integrate as spi
并使用spi.quad
来自文档(或者更确切地说,SciPy 的 __init__.py
文件):
...
Subpackages
-----------
Using any of these subpackages requires an explicit import. For example,
``import scipy.cluster``.
::
cluster --- Vector Quantization / Kmeans
fftpack --- Discrete Fourier Transform algorithms
...
integrate --- Integration routines [*]
...
