Could PPO solve DM control tasks?

[zhihaocheng]

I install RLzoo and use its PPO to train an agent for DM Control Suite. I tested environments CheetahRun-v0 and CartpoleSwingup-v0, but the current PPO could solve neither of both. Could you please help me? I attach the testing reward for CartpoleSwingup-v0 below.
