Running viewer without an environment

[tkelestemur]

I'm loading a custom MuJoCo environment and I want to run the viewer without defining a RL environment and task. Below is the way I load the XML file:

MODEL_PATH = PATH + '/models/data_collection.xml'

physics = mujoco.Physics.from_xml_path(MODEL_PATH)
pixels = physics.render()

Is this possible?

Hello,

Currently the viewer supports only the environment visualisation.

Best regards, Piotr Trochim

@tkelestemur Can you describe your usecase? (If it is to view the model without additional requirements MuJoCo provides a viewer onto which you can drag an xml file.)

[tkelestemur]

@iandanforth I can easily use MuJoCo's viewer but I wanna use dm_control as the python wrapper with a viewer that I can run from python code. I don't need to define an RL environment for my case.

@tkelestemur How about this.

If you save both of those files to dm_control/dm_control/suite

You should then be able to use xml-explore.py like this:

python xml-explore.py <yourfile>.xml

Here's what it looks like running my muscled-ant.xml model with custom textures saved in the same dir.

If you compare empty.py with the original cartpole.py you should be able to add back in any functionality you need to get a real task running. Consider this a minimal starting point.

If you just want to launch a viewer from python, the xml-explore.py bits should help.

@iandanforth This worked great. The only drawback is that every time I change something in the empty.py I need to install dm_control again. Other than that this is all I needed.

Thanks a lot!
