[英]python dot operator in 'from import' statement
from . import _nd_image
My question is that there is no such file _nd_image.py in the current directory and code uses this above import statement and below, somewhere in code there is a statement _nd_image.fun()
. 我的问题是,当前目录中没有这样的文件_nd_image.py,代码在import语句上方和下面使用此代码,在代码中的某处有
_nd_image.fun()
语句。

The code is taken from here 代码是从这里获取的
import statement in at line no.36
and usage of _nd_image is at line no. _nd_image的用法在第no行。 143

There is probably a file _nd_image.pyd
or _nd_image.so
in the directory. 目录中可能有一个文件
_nd_image.pyd
或_nd_image.so
