Description
RLlib has three custom spaces
FlexDict,RepeatedandSimplex. These are historic artifacts of RLlib IMO with Gymnasium now providing equivalent spaces withDictforFlexDictandSequenceforRepeated.I haven't removed
Simplexas an equivalent space within Gymnasium doesn't exist but I don't believe there is any testing of if this space works in RLlib stack currently.
