Requesting simple RDPG example

[satpreetsingh]

Hi, could you help me get a simple RDPG example using, say, Pendulum-v0 working?

I tried to invoke using the following on an Ubuntu + Pytorch 1.4.1 system, but am running into errors:

python apex.py rdpg --env_name Pendulum-v0 --run_name pendulum_rdpg

I fixed several pathname related issues, but am still running into missing modules etc.

Traceback (most recent call last):
  File "apex.py", line 116, in <module>
    run_experiment(args)
  File "/home/apex/rl/algos/dpg.py", line 208, in run_experiment
    from rl.policies.critic import FF_Critic, LSTM_Critic
ImportError: cannot import name 'FF_Critic' from 'rl.policies.critic' (/home/apex/rl/policies/critic.py)

Thanks in advance!
