uv support

[KTibow]

Recommended start

uv does NOT try to install all extras. however, it tries to resolve them. read more about universal resolution

Each extra should be individually installable without conflicting with the core dependencies

• avalon: gym==0.25.2 -> doesn't work with gym 0.23
• atari
• box2d
• bsuite: deprecated & breaks in 3.12+; leanke: "can be dropped"
• butterfly
• classic_control
• crafter
• craftax
• dm_control
• dm_lab
• griddly
• kinetix: requires Python 3.10+
• magent: not magent2 -> pettingzoo==1.19.0 -> doesn't work with pettingzoo 1.24.1
• metta: locked at Python 3.12 -> incompatible, see requires-python is being handled too strictly w/ extras astral-sh/uv#15399. also since sep 18 the mettagrid subdirectory hasn't existed
• microrts
• minerl: gym==0.17.0 -> doesn't work with gym 0.23
• minigrid
• minihack
• mujoco: gymnasium[mujoco]==1.0.0 -> doesn't work with gymnasium 0.29.1
• nethack
• nmmo: uses old numpy & breaks in 3.12+
• open_spiel: pettingzoo==1.19.0 -> doesn't work with pettingzoo 1.24.1
• pokemon_red: relies on pandas==2.0.2 which breaks on some devices; leanke: "can be dropped"
• procgen
• slimevolley: probably meant to be slimevolleygym but that has import issues too, seems broken
• vizdoom
• ray
• cleanrl

Extras shouldn't conflict with each other

many deps use pygame, therefore conflicting with each other:

• magent (not using magent2, therefore locked to pygame 2.1.0)
• pettingzoo butterfly (locked to the old 1.24.1, therefore locked to pygame 2.3.0)
• box2d (pygame >= 2.1.3)
• minigrid (pygame >= 2.4.0)
• vizdoom (pygame >= 2.1.3)

nethack directly depends on nle == 0.9.1 while minihack depends on nle == 0.9.0

Use conflicts to solve

4.0 specific

need to put requires-python = ">=3.10" in setup.py because torch requires python >= 3.10

If it gets good, recommend using uv?
