you need a file named   init   py  two underscores on each side  in every folder in the hierarchy  so one in src  and one in model   This is what python looks for to know that it should access a particular folder  The files are meant to contain initialization instructions but even if you create them empty this will solve it

All modules in Python have to have a certain directory structure  You can find details here  Create an empty file called   init   py under the model directory  such that your directory structure would look something like that     -- project      -- src          -- hello-world py          -- model              --   init   py              -- order py  Also in your hello-world py file change the import statement to the following  from model order import SellOrder  That should fix it P S   If you are placing your model directory in some other location  not in the same directory branch   you will have to modify the python path using sys path

You need to make sure the module is installed for all versions of python  You can check to see if a module is installed for python by running   pip uninstall moduleName  If it is installed  it will ask you if you want to delete it or not  My issue was that it was installed for python  but not for python3  To check to see if a module is installed for python3  run   python3 -m pip uninstall moduleName  After doing this  if you find that a module is not installed for one or both versions  use these two commands to install the module    pip install moduleName python3 -m pip install moduleName

If it s your root module just add it to PYTHONPATH  PyCharm usually does that  export PYTHONPATH  PYTHONPATH  lt root module path gt   for Docker  ENV PYTHONPATH  quot   PYTHONPATH   lt root module path in container gt  quot
