cannot fully log the reward

[cocosun1121]

Dear all:
when I train my model, the event.out document cannot record the training information , and the log is lack of the record of reward, as shown below:
| Trial name | status | loc |
|----------------------------------------+----------+------------------|
| MAPPOTrainer_EnvMDP_EnvMDP_2d068_00000 | RUNNING | 127.0.0.1:185332 |
+----------------------------------------+----------+------------------+
PLZ tell me why, thank you very much!
