训练结束后，会生成
events.out.tfevents.1583152456.sharmen-System-Product-Name文件，上面的代码时将该结果文件给做出图、将数据提取出来
输出结果包括：
[‘eprewmean‘, ‘misc/serial_timesteps‘, ‘misc/nupdates‘, ‘misc/time_elapsed‘, ‘eplenmean‘, ‘misc/total_timesteps‘, ‘loss/approxkl‘, ‘loss/clipfrac‘, ‘loss/policy_entropy‘, ‘misc/explained_variance‘, ‘loss/value_loss‘, ‘loss/policy_loss‘, ‘fps‘]
