无法从另一个目录导入文件，该目录从同一目录导入文件（int Python）

Question

So my project structure is the following:

project/
    src/
        __init__.py
        utils.py
        model.py
    usage.py

I now want to import functions from utils.py and a class in model.py into my usage.py. But the model.py itself imports functions from utils.py.

So I am doing the following:

# usage.py

from src.model import Model
from src.utils import onehot_to_string

But I am getting the error that it couldnt import functions from utils.py into the model.py:

File "usage.py", line 11, in <module>
    from src.model import *
  File "/project/src/model.py", line 7, in <module>
    from utils import onehot_to_string
ImportError: cannot import name 'onehot_to_string' from 'utils' (/lib/python3.7/site-packages/utils/__init__.py)

I think I am lacking of some basic Python packaging knowledge here. Can someone help me out? :)

Answer 1

for file/function/variables importing use this sys method

import sys
# insert at 1, 0 is for other usage
sys.path.insert(1, '/path/to/application/app/folder')

Looks like python can't find your utils file in module.py . Then it proceeds to search for utils in path and finds it as you have probably installed some library name utils. Then this utils file has no onehot_to_string function.

Try to change your from utils import onehot_to_string to from.utils import onehot_to_string in model.py to use relative import.
