The SPDX (software package data exchange) check, checks that all the files in the repo have an open source license. I don’t think it is a fatal check. You can probably ignore it for chipIgnite projects.
If you wanted to make sure your design passes, include an SPDX header in all the files.
In your case, it appears that there is a python environment installed within your project repo. It might be easiest to install that outside the repo.
