ModuleNotFoundError: No module named <>

I’m trying https://developers.google.com/protocol-buffers/docs/pythontutorial wherein I have created a directory structure like this:

└── address_book
    ├── proto
    │   ├── addressbook.proto
    │   └── addressbook_pb2.py
    └── src
        └── write.py

write.py content:

import os
import sys

PROJECT_ROOT = os.path.abspath(os.path.join(
                  os.path.dirname(__file__), 
                  os.pardir)
)
sys.path.append(PROJECT_ROOT)

from address_book.proto import addressbook_pb2 as ab

So now when I try to execute write.py, I run into following error:

(venv) 15:53:32:~/Desktop/work/mbip/protobufs % python
address_book/src/write.py Traceback (most recent call last): File
"address_book/src/write.py", line 10, in
from address_book.proto import addressbook_pb2 as ab ModuleNotFoundError: No module named ‘address_book’

>Solution :

try this,

import os
import sys

PROJECT_ROOT = os.path.abspath(os.path.join(
                  os.path.dirname(__file__), 
                  os.pardir)
)

# print(sys.path)
sys.path.append(PROJECT_ROOT)
# print(sys.path)

#you don't need the parent dir again since you already added it to the path

from proto import addressbook_pb2 as ab
