ModuleNotFOundError: No module named 'numpy.ma'; 'numpy' is not a package

Question

我已经在 Windows 10 上安装了 Numpy 1.13.0；但是，当我尝试执行以下代码时，它给出了上述错误

#!C:\Users\sukhpreet.singh\AppData\Roaming\Microsoft\Windows\Start Menu\Programs\Anaconda3 (64-bit)
import numpy as np 
import matplotlib.pyplot as pp 
a = np.array([1,2,3,4,5])
print(a.dtype)

错误信息详情如下：

Traceback (most recent call last):

ModuleNotFoundError: No module named 'numpy.ma'; 'numpy' is not a package

Answer 1

您在 python 的搜索路径（位于 C:\Users\sukhpreet.singh\Project\numpy.py）上还有一个名为 numpy 的模块。

不出所料，当 matplotlib 尝试导入 numpy.ma 时，它找到的是你的 numpy 模块，而不是库包。

结论：不要将您的模块命名为与您想要使用的其他 packages/libraries 相同的模块。
