Preface
Sometimes it’s necessary to set up an reinforcement learning environment, but I found that I have to start the configuration from scratch every time, so it’s better to keep a record…
Quick Installation of Mujoco Environment
- Step 1: Download to the
/root/directory (Terminal’s~/directory)
wget https://mujoco.org/download/mujoco210-linux-x86_64.tar.gz
- Step 2: Extract to
.mujoco/
mkdir ~/.mujoco # Create
tar -zxvf mujoco210-linux-x86_64.tar.gz -C ~/.mujoco
- Step 3: Append environment information
echo "export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/root/.mujoco/mujoco210/bin" >> ~/.bashrc
source .bashrc
- Step 4: Install relevant Python libraries in the corresponding conda environment
pip install mujoco
pip install mujoco-py
Changing sources: Ubuntu’s software source configuration file is /etc/apt/sources.list. Make a backup of the system’s default file and replace it with the following content to use the selected software source mirror. (Although it may not be necessary on a PC, it may be necessary on a server)
# The source code mirror is commented out by default to improve apt update speed. Uncomment if needed

You can use the vim command to complete it:
vim /etc/apt/sources.list
### --- ###
# In vim view
# Clear sources
# `gg` jump to the beginning of the file, d delete G until the end of the file
ggdG
# Then paste the above code
