Also, why when I run kedro run it works, but when I run using python src/../nodes.py it show no module named xxx?

kedro run

dynamically modifies the path during a local run to include the

src/

folder. (This makes sense, because packagin a Kedro project would expose the module defined in

src/

, and this is just a fairly standard practice is using a src layout (see https://packaging.python.org/en/latest/discussions/src-layout-vs-flat-layout/, if you don't know what that is).

@Jackson The short answer is you should do

pip install -e .

to install that package.
