Tensorboard那些事

from tensorboard.backend.event_processing import event_accumulator

#加载日志数据
ea=event_accumulator.EventAccumulator(r‘G:proj_drlopenai-2020-03-02-20-25-20-731960	bevents.out.tfevents.1583152456.sharmen-System-Product-Name‘) 
ea.Reload()
print(ea.scalars.Keys())

eprewmean=ea.scalars.Items(‘eprewmean‘)
print(len(eprewmean))
print([(i.step,i.value) for i in eprewmean])

import matplotlib.pyplot as plt
fig=plt.figure(figsize=(6,4))
ax1=fig.add_subplot(111)
eprewmean=ea.scalars.Items(‘eprewmean‘)
ax1.plot([i.step for i in eprewmean],[i.value for i in eprewmean],label=‘eprewmean‘)
ax1.set_xlim(0)
eplenmean=ea.scalars.Items(‘eplenmean‘)
ax1.plot([i.step for i in eplenmean],[i.value for i in eplenmean],label=‘eplenmean‘)
ax1.set_xlabel("step")
ax1.set_ylabel("")

plt.legend(loc=‘lower right‘)
plt.show()

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‘]
