问题描述
当我运行 flow/envs/ring/lane_change_accel 时，出现错误：

IndexError: boolean index did not match indexed array along dimension 0; dimension is 0 but corresponding boolean dimension is 1
我不知道代码是什么(
non_lane_changing_veh = \
[self.time_counter <=
self.env_params.additional_params["lane_change_duration"]
+ self.k.vehicle.get_last_lc(veh_id)
for veh_id in sorted_rl_ids]
) 表示，因为 non_lane_changed_veh 看起来不像一个整数。 谁能告诉我什么是错的，我认为代码不正确
