NeurIPS 2019: Learn to Move - Walk Around

Observation Dictionary to List Function

Over 4 years ago

It all looks the same to me, I also tested it to make sure the results are the same as using project=True and obs_as_dict=False. Unless I’m missing something, the only difference I can see is the first 3 velocities of the pelvis being divided by self.LENGTH0, not sure what that is. But at the very least your method is much more clean and concise.

Speed of training

Over 4 years ago

There’s an integrator_accuracy parameter in the environment constructor, which determines the accuracy of the simulation, a smaller value being more accurate and more time consuming. I believe the default is 0.00005, and I’ve been able to successfully set it up to about 0.005 (the environment crashes with larger values). Example: env=L2M2019Env(integrator_accuracy=0.005). It can make a noticeable difference in training speed, but nothing insane.

Wrong Client Version Problem

Over 4 years ago

I had this same problem, just reinstalling stuff wouldn’t work for me, but fully creating it all in a new environment worked (i.e. creating opensim-rl2 env).

The promotion code you entered is not valid - Google Cloud

Yes that works, thank you.

The promotion code you entered is not valid - Google Cloud

Over 4 years ago

The code I received through email for google cloud credits doesn’t work and gives me the error β€œThe promotion code you entered is not valid”. I remember having this issue last year along with others, and was unable to receive the credits. Am I able to get a new code for this or were the codes just not activated yet?

Observation Dictionary to List Function

Over 4 years ago

For my training and executing I use the list instead of the dict, and I didn’t manage to find a provided way to convert the observation dictionary to a list (as it’s required in submission). So I just made my own method for doing so with consistent ordering: https://gist.github.com/Ryan-Amaral/960c291d7cafe928a725f60f36e1f549, hopefully it is of use to someone else.

Was there actually a provided way to do this that I missed? Oh well, it didn’t take too long either way.

Modification of Environment Physics

Over 4 years ago

Great thanks, it worked!

Modification of Environment Physics

Over 4 years ago

Is there a relatively simple way to modify certain parameters of the environment, such as gravity level, friction, etc? For example I tried modifying the β€˜G’ variable found in the L2M2019Env class both on the class and instance level, but it seems to make no change. I’m also starting to look into the osim package code, but not sure if that will pay off.
