Python ModuleNotFoundError：没有模块名为x时try 运行我的代码''

我真的束手无策，try 了多种解决方案，包括使用setup.py文件，将相对导入更改为绝对导入，反之亦然，包重组，确保每个包都是__init__. py文件等等.任何帮助将不胜感激.下面我简化了我的项目.

我的项目 struct 如下:

myProject
   |
   |__ src
        |
        |__ foo
        |     - __init__.py
        |    |
        |    |__ bar
        |          - __init__.py
        |         |
        |         |__ baz
        |              - __init__.py
        |              - baz_functions.py
        |              - baz_watch.py
        |
        | - __init__.py
        | - project_code.py
        | - main.py

至于档案:

main.py

import project_code

if __name__ == '__main__':
    project_code.run()

project_code.py

import foo.bar.baz.baz_functions

def run():
    print('Hello World!')

baz_watch.py

from baz_functions import function_1, function_2

print('Watching...')

baz_functions.py

def function_1():
   print('I am function 1')

def function_2():
   print('I am function 2')

当然，没有project_code.py中的:import foo.bar.baz.baz_functions，代码运行正常.

我得到的错误是:

Traceback (most recent call last):
  File "C:\xxx\xxx\xxx\myProject\src\main.py", line 1, in <module>
    import project_code
  File "C:\xxx\xxx\xxx\myProject\src\project_code.py", line 1, in <module>
    import foo.bar.baz.baz_functions
  File "C:\xxx\xxx\xxx\myProject\src\foo\bar\baz\baz_watch.py", line 1, in <module>
    from baz_functions import function_1, function_2
ModuleNotFoundError: No module named 'baz_functions'
