I am trying to set up an editable install of PyDelphin so that I can expand the
MRS package somewhat. (I want to create a
SEMENT class, which I have another post about here).
I am having trouble with the editable install breaking the import statements.
My directory structure is something like this:
pip install -e ./pydelphin from the
sandbox/ directory per the installation instructions.
pip list I see the following for PyDelphin:
PyDelphin 1.6.0 /Users/elizabeth/Documents/sandbox/pydelphin
This suggests to me that the install worked correctly and has been installed from the directory I cloned. But now all of the imports are broken and anything that starts with
from delphin or
import delphin is an unresolved reference. If I do
from pydelphin.delphin it works, but I don’t think this is what should be happening. I would’ve expected the editable install to resolve these paths correctly but it isn’t for some reason.
Hmm, that’s interesting. I’m not seeing that when I try a fresh install:
$ mkdir pytmp
$ cd pytmp
~/pytmp$ gh repo clone delph-in/pydelphin

PyDelphin uses PEP-420 implicit namespace packages to support plugins, so one thing that could go wrong is if you have somewhere on your Python path (perhaps under
delphin/ subdirectory containing an
Another thing is to make sure you are installing PyDelphin to the right environment, whether you’re using a virtual environment (as above) or your system one.
Does this info help?
