Question about visualize the change of reward when training

[huangjiancong1]

Why we use test() to see the reward and testing_sample_step?

Can I use the train() to see how the reward change when training?
It seems that the last perf is the reward.

Because we want to compare with the openai,

The test() function disable exploration for testing the performance of deterministic policies.
0.0.monitor.csv contains training performance (with exploration)
0.1.monitor.csv contains testing performance (without exploration)
