Failed to create distribution archives

[carme-hp]

If I run
python setup.py sdist
I get
error: Invalid distribution name or version syntax

My folder structure is the following:

diffusion2d/
├── setup.cfg
├── setup.py
├── README.md
├── carme-hp-diffusion2d/
│    ├── difussion2d.py
│    └── output.py

In setup.py I have:

from setuptools import setup

setup()

And in setup.cfg I have:

[metadata]
name="carme-hp-diffusion2d"
version="0.0.1"
author="Carme Homs-Pons"
url="https://github.com/carme-hp/diffusion2D?organization=carme-hp&organization=carme-hp"
description="A introduction to packaging using a diffusion2d example"

I can make it work by moving name="carme-hp-diffusion2d" to setup.py or just by removing the name tag, in which case the default name tag UNKNOWN is used.
