ActorFixSAC or AgentBase的__init__有bug?

1. 运行 tutorial_LunarLanderContinuous_v2.ipynb 报错：
2. ElegantRL\elegantrl\agents\AgentBase.py:58, in AgentBase.__init__(self, net_dim, state_dim, action_dim, gpu_id, args)
56 cri_class = getattr(self, "cri_class", None)
57 print(act_class)
---> 58 **self.act = act_class(net_dim, state_dim, action_dim).to(self.device)**
59 self.cri = cri_class(net_dim, state_dim, action_dim).to(self.device) \
60 if cri_class else self.act
62 '''optimizer'''

TypeError: __init__() missing 1 required positional argument: 'action_dim'
3. 看了一下,调用的是 net.py ActorFixSAC 的def __init__(self, mid_dim, num_layer, state_dim, action_dim):
4. 多了一个参数num_layer， 而且其它地方也没有用， 应该要把这个里删除吧。
5. 我修改AgentBase 的init 总算成功运行了：self.act = act_class(net_dim, self.num_layer, state_dim, action_dim).to(self.device)
self.cri = cri_class(net_dim, self.num_layer, state_dim, action_dim).to(self.device)
