Comments

All scripts are provided for reproducing the examples in the paper.
The dependencies can be easily installed using a script, but on ubuntu 19.10 I had to install libnlopt-cxx-dev.
The policy learning went well, but I was not able to produce the results of the paper, due to the failure of the test_policy function with error: Attempted to look up malformed environment ID: b'../data/precomp_data/dog_run1/policy_params.pkl'. (Currently all IDs must be of the form ^(?:[\w:-]+\/)?([\w:.-]+)-v(\d+)$.)
This occured also when testing the provided precomputed policies.

I also tried with an older release of dart-env (v0.7.4 - 2017) which seems to be handling registration but the same problem occured.
