DefaultModelConfig.fcnet_hiddens: List[int]

List containing the sizes (number of nodes) of a fully connected (MLP) stack. Note that in an encoder-based default architecture with a policy head (and possible value head), this setting only affects the encoder component. To set the policy (and value) head sizes, use post_fcnet_hiddens, instead. For example, if you set fcnet_hiddens=[32, 32] and post_fcnet_hiddens=[64], you would get an RLModule with a [32, 32] encoder, a [64, act-dim] policy head, and a [64, 1] value head (if applicable).
