ERROR: Could not open disk

  1. Hi,
    I am trying to run this code with Mujoco Pro license in OSX but I am getting this
    ERROR: Could not open disk

    Code is

    import gym
    env = gym.make('Hopper-v1')
    env.reset()
    env.render()

    I have setup the mjpro131 properly, I had mjpro150 but the openAI code gave an error that 1.31 should be used so downloaded and placed the mjkey in bin and ran but failed, so followed the steps mentioned in Mujoco documentation and I am still getting the same error "ERROR: Could not open disk"

    This happens on Macs with NVMe disks and MuJoCo versions prior to 1.50. It was fixed in 1.50, but there is no way to go back in time and fix it in older releases... unless I misunderstand your post... are you saying you got this error with 1.31 or 1.50?
     
  3. 1.50 works fine and its amazing, I was trying OpenAI Mujoco models which needs 1.31 version but as you said it can't be fixed, thank you for the help professor
