错误出现于env.set_actions()传递action至环境时出现，具体错误以下： The behavior needs a discrete input of dimension (xx, xx) for (<number of agents>, <action size>) but received input of dimension (xx, xx)

对应方法

只是discrete/continuous动作的shape没有对上，和(<number of agents>, <action size>)毫无关系，只需检查discrete/continuous动作shape即可。
