How to setup the dev environment?

Describe the question you have

I feel stupid for having to ask this, but boxing with this for too long I am at my wits end...

I followed what I could find in the docs, cloned the repo, checked out a tag (just for reference 2.0.4), pip install -e . and installed dependencies from makefile etc. Running the make test yields

So either a lot of tests are knowingly failing, the requirements are not properly defined, or i am doing something wrong.
