描述

Proposal

Add dtype argument to spaces.Discrete (similar to MultiDiscrete and Box).

Motivation

Currently the dtype is fixed to numpy.int64. However, often Discrete spaces are much smaller, resulting in a waste of memory.

研究方向
The Discrete space implementation is located in gymnasium/spaces/discrete.py. Similar dtype parameters exist in MultiDiscrete and Box spaces, which can serve as reference. The issue has 3 comments suggesting potential implementation details. No linked PRs. The task involves adding a dtype parameter to the init method and ensuring it is used in sampling and other methods.
