ddpg.keras-rl.py actual directory

[ghost]

This could possibly be just a noob mistake for not discovering it easily, but the information in the Training Your First Models page could be quite confusing for some.

In particular, with respect to the latest osim-rl package, the ddpg.keras-rl.py script is actually located in the osim-rl/examples/under-construction directory rather than the osim-rl/example directory.

Hence the cd osim-rl/examples command in the respective page needs to be updated to cd osim-rl/examples/under-construction in order to run the following commands.

@fairread Yes, you are right. That page is out of date. Please refer to this page: http://osim-rl.stanford.edu/docs/nips2019/training/

But that doesn't work either... @smsong
Following that http://osim-rl.stanford.edu/docs/nips2019/training/ page, when I execute the:

python -m examples.train_arm --train --model sample

I get this error:

ModuleNotFoundError: No module named 'rl'

It requires keras-rl, I'll update the doc, thanks for reporting!
