I am sorry this question should fit better to mujoco-python forum, but I asked there several days ago and nobody responds (it looks like that forum has been dead for a while), so I just check here if anyone happens to encounter this: I am trying to load my .xml file (converted from urdf) into mujoco by mujoco python: mujoco_env.MujocoEnv.__init__(self, "someFilePath/Silvia.xml", 5) and I get the following error: File "/home/xuan/.local/lib/python3.5/site-packages/gym/envs/mujoco/mujoco_env.py", line 98, in do_simulation self.sim.data.ctrl[:] = ctrl TypeError: 'NoneType' object does not support item assignment My .xml file is attached. Did any one happen to be able to solve that?
Solved... Need to manually put in root joint, camera and motors, ./compile doesn't do this automatically
