Importing Python Package - "importerror: No Module Named..."

I know there are a lot of questions about 'ImportError: No module named...' but they ususally seem to boil down to no __init__.py file or the package directory not in $PYTHONPATH.

Solution 1:

Let say you have below structure :

demo_proj
    |
    myproject/
    ├── module
    │   ├── __init__.py
    │   └── module.py
    └── main.py

    myprotos/
    ├── Makefile
    ├── __init__.py
    ├── my.proto
    ├── my_pb2.py
    ├── myprotos.egg-info
    │   ├── PKG-INFO
    │   ├── SOURCES.txt
    │   ├── dependency_links.txt
    │   └── top_level.txt
    └── setup.py

Code in main.py:

import sys
sys.path.insert(0, '/path/to/demo_proj')

import myprotos
