Because autoflake (2.3.1) depends on pyflakes (>=3.0.0)
 and flake8 (3.9.2) depends on pyflakes (>=2.3.0,<2.4.0), autoflake (2.3.1) is incompatible with flake8 (3.9.2).
And because no versions of flake8 match >3.9.2,<4.0.0, autoflake (2.3.1) is incompatible with flake8 (>=3.9.2,<4.0.0).
So, because cognite-transformations-cli depends on both flake8 (^3.9.2) and autoflake (=2.3.1), version solving failed.
