how to get the weights_dense1_w?

[steven]

i find many parameters like weights_dense1_w in the example, these parameters should be the result trained by other modules. i want to know where can i find these modules? Any other related document is also helpful. thanks.

Just for your reference.
1. site-packages/pybullet_envs$ python3.5 -m agents.train_ppo --logdir=./ --config=pybullet_humanoid
2. use the tf.train.NewCheckpointReader(checkpoint_path) to get the parameters that you need.
