python3：numpy 有效，但 numpy.integrate 无效

Question

我在 python3 中使用 numpy 进行数学项目。今天，我想使用 numpy.integrate.quad，但您可以在下面看到错误和进一步的尝试。 import numpy 始终有效。那怎么回事？

$ python
Python 3.6.1 (default, Mar 27 2017, 00:27:06) 
[GCC 6.3.1 20170306] on linux

>>> import numpy as np
>>> import numpy.integrate as integrate
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ModuleNotFoundError: No module named 'numpy.integrate'
>>> import scipy.integrate as integrate
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ModuleNotFoundError: No module named 'scipy'
>>> from numpy import integrate
Traceback (most recent call last):

ImportError: cannot import name 'integrate'
>>> from scipy import integrate

    from numpy import integrate.quad

Numpy好像安装正确了，但是我还是不能用numpy.integrate。我在搞乱进口吗？

Answer 1

from scipy.integrate import quad

numpy 没有 integrate 包；这些在交付的 scipy 部分。

python3：numpy 有效，但 numpy.integrate 无效

python3: numpy works, but numpy.integrate doesn't
