Import Error while importing module from sibling directory

Question

I was hacking over the weekend and happened across a strange issue. For some reason I Cant import modules from a sibling directory. I have no issues importing from a parent:

| src/
| ---- __init__.py
| ---- lib/
| -------- __init__.py
| -------- MyModule1.py
| -------- MyModule2.py # <--- I have no issues running `from src.lib.MyModule1 import MyModule1`
| ---- test/
| -------- __init__.py
| -------- MyTestModule1.py # <--- I cannot run `from src.lib.MyModule1 import MyModule1`

I have two modules in my lib directory, MyModule and MyModule2, and a test in my test dir. Modules in lib can use other modules as long as they have the same parent (lib/) but for some reason, modules in lib's sibling test/ cannot use modules in lib/.

When I try to run MyTestModule.py:

from src.lib.MyModule1 import MyModule1

I get this error: ImportError: No module named 'src'.

I do not get this error while running the same code in lib/MyModule2.py

What is going on here? Please help.

How do you run `MyTestModule.py`? What is the working directory? — Peter Wood, Jun 12 '17 at 23:50
eh, I'm using pytest from the project root. so one level above `src/` — dopatraman, Jun 13 '17 at 00:34
