How to properly import an existing Django project in Eclipse/Pydev? - django

Question

I cannot figure how to import correctly an existing Django project in Eclipse/Pydev, and I can't find my way in the documentation of Pydev. My question is pretty simple : I have an existing project from a different computer, that I want to migrate on a new one.
I installed Eclipse and Pydev on the new machine, and everything seems normal for a new project: I can create a new Django project and run it without issue. I also have been able to import my pre-existing project, but when I run the project, I encounter the following error :
Finding files... done.

ipaidenv is the name of my conda environment, Test is the project name.
I am pretty sure there is something very simple that I didn't do right, but I can't find what, can anyone help?
Many thanks!
