Add Poetry

[alecandido]

Close #23

@yjmaxpayne at the end, I needed it for something else, so I already defined the Poetry configuration.

I still have to check that everything is alright, and that it fully replaces setup.py.

Hi Alessandro, thanks a lot for implementing this. I noticed missing dependencies on Qibo and Qibojit. Please add them in to ensure at least the tests/test_quimb_backend.py can pass.

[yjmaxpayne]

Great, thanks for the revisions.

@alecandido thanks for this, could you please fix the conflict so we can merge?

[scarrazza]

It looks like cannot find qibo 0.2.4.

[alecandido]

I updated the lock file, but I had no problem in installing.

Could you please provide the error log?

Poetry is not using pip any longer, but it's using the same install library used by pip, and for me it is able to resolve.

From the build I see

ERROR: Could not find a version that satisfies the requirement qibo<0.3.0,>=0.2.4 (from qibotn) (from versions: 0.0.1b3, 0.0.1b4, 0.0.1b5, 0.1.0, 0.1.1, 0.1.2, 0.1.3, 0.1.4, 0.1.5, 0.1.6rc0, 0.1.6rc1, 0.1.6, 0.1.7rc0, 0.1.7rc1, 0.1.7, 0.1.8rc0, 0.1.8, 0.1.9, 0.1.10, 0.1.11, 0.1.12, 0.1.13, 0.1.14, 0.1.15, 0.1.16, 0.2.0, 0.2.1, 0.2.2)

That workflow is largely outdated, however, I tried to reproduce the steps locally, and I could not (to me it also installs correctly with pip, and the steps written there).

I'm trying to update the workflow (I don't want to use yet the reusable ones, because we still have to decide how to address #28).

[alecandido]

My bad: it was already using the reusable ones. Since we're already there I just moved to the Poetry version (the one we use in all the other repos), and keep debugging with that one.

[alecandido]

@scarrazza: ok, now it is failing because of the dependencies, but this is because of #29.

I'd say it is now out of the scope of this PR.

[scarrazza]

Ok, shall we merge?
