Commands for MuJoCo installation #10

Closed DanielTakeshi closed 7 years ago

DanielTakeshi commented 7 years ago

For anyone who has gotten the code to run successfully, what commands did you put in for your MuJoCo installation? In the dependency file we have this area:

#######################################################
# WRITE CODE HERE TO PLACE MUJOCO 1.31 in /opt/mujoco #
# The key file should be in /opt/mujoco/mjkey.txt     #
# Mujoco should be installed in /opt/mujoco/mjpro131  #
#######################################################

I assumed it would be something like:

sudo cp -r [?????]/mjpro131/ /opt/mujoco/
sudo cp [?????]/mjkey.txt /opt/mujoco/

But I am not sure what to put in the [?????]. I have MuJoCo 1.31 for my personal computers, but if I try to copy it there with, e.g. sudo cp -r ~/mjpro131/ /opt/mujoco/ and sudo cp ~/mjpro131/mjkey.txt /opt/mujoco/ I get the following after building the packer script:

    amazon-ebs: + sudo mkdir -p /opt/mujoco
    amazon-ebs: + sudo cp -r /home/ubuntu/mjpro131/ /opt/mujoco/
    amazon-ebs: cp: cannot stat '/home/ubuntu/mjpro131/': No such file or directory
    amazon-ebs: + sudo cp -r /home/ubuntu/mjpro131/mjkey.txt /opt/mujoco/
    amazon-ebs: cp: cannot stat '/home/ubuntu/mjpro131/mjkey.txt': No such file or directory
    amazon-ebs: + sudo tee /etc/profile.d/mujoco.sh
    amazon-ebs: + sudo echo 'export MUJOCO_PY_MJKEY_PATH=/opt/mujoco/mjkey.txt'
    amazon-ebs: + sudo tee -a /etc/profile.d/mujoco.sh
    amazon-ebs: + sudo echo 'export MUJOCO_PY_MJPRO_PATH=/opt/mujoco/mjpro131'
    amazon-ebs: + . /etc/profile.d/mujoco.sh
    amazon-ebs: ++ export MUJOCO_PY_MJKEY_PATH=/opt/mujoco/mjkey.txt
    amazon-ebs: ++ MUJOCO_PY_MJKEY_PATH=/opt/mujoco/mjkey.txt
    amazon-ebs: ++ export MUJOCO_PY_MJPRO_PATH=/opt/mujoco/mjpro131
    amazon-ebs: ++ MUJOCO_PY_MJPRO_PATH=/opt/mujoco/mjpro131

In other words, the packer script thinks MuJoCo is in /home/ubuntu instead of my personal machine. Is there a different command to use for this?

Never mind, figured it out. Use the file provisioner before running the script to get the MuJoCo files copied over to the machines.
