博客讲述了在Python中导入munkres库时遇到问题，原因是自定义的Python文件命名为munkres.py，导致导入时出错。此外，还验证了很多库在Python2和Python3环境下无冲突，给出了导入错误的具体信息。

用到了一个叫做munkres的库

但每次import的时候都出现了问题

后来找到问题是我自己的python file 命名为munkres.py 

所以每次它import 的时候都是import 我自己的python file 

python 这一点也挺不好的，感觉就是很随意的，interpreter一脸懵逼？

还有问题是不是很多库都是python2 和python3 共同使用的，就是没有冲突，为了验证这一点我还特意搞了python2的环境，结果是没有冲突。

Traceback (most recent call last):
  File "f:/PythonDev/benchmarks/scripts/import_munres.py", line 5, in <module>

ImportError: cannot import name 'Munkres' from 'munkres' (f:\PythonDev\benchmarks\scripts\munkres.py)

ModuleNotFoundError: 未找到名为“No_module_named“的模块的通俗解释和解决方法

模块未安装：如果你尝试导入的模块是第三方模块或自定义模块，但你没有将其安装到你的Python环境中，那么就会出现ModuleNotFoundError。你可以使用pip工具来安装第三方模块，或者确保你的自定义模块位于正确的路径下。模块路径问题：Python解释器在导入模块时会搜索一系列目录，这些目录包括Python标准库和你自己编写的模块所在的目录。通过理解ModuleNotFoundError的常见原因，并根据具体情况采取相应的解决方法，你应该能够解决这个错误并成功导入所需的模块。

解决python导入自定义模块报错ImportError: No module named XXX

在进行python代码开发，尤其是进行代码部署时，明明在IDE（如Pycharm）中运行正常的代码，到了生产环境使用python xxx.py方式运行时，就报各种各样的ImportError: No module named XXX，找不到各种自定义的代码文件，产生这个问题的原因是python的搜索路径导致的，具体原因请自行搜索。下面说一种解决方法： 示例代码结构如下： utils.tools目录下有tools.py代码文件，demo.py文件在utils目录下，也就是在tools.py的上级目录.
