你好，我在代码自定义环境中指定action_space范围为-1到1，但是网络输出的action只有0-1，请问是bug还是有其他地方需要配置

It is might because the activation function of the last layer in the actor-network is set as "sigmoid". In the newest version of XuanCe (v1.2.1), you can set the activation_action attribute to control the output range of actor networks.
