To access the terminal on macOS, use Cmd+Space to enter Spotlight Search, then search for “Terminal” and hit enter to open it. Next, follow these steps to install LabGym.

Install the Xcode command line tools, a software package provided by Apple that includes git and a C/C++ compiler named clang.
```
% xcode-select --install
```
A GUI installation window should pop up. Follow along and accept all the default values.
Install Homebrew, a command-line package manager for macOS that will simplify the installation of Python. To install Homebrew, run the following command:
```
% /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"
```
Note

If you’re on an Apple Silicon Mac, you will need to add Homebrew to PATH. To do this, enter the following command, then close and reopen your terminal window.
```
% echo 'eval $(/opt/homebrew/bin/brew shellenv)' >> ~/.zprofile
```
Use Homebrew to install Python 3.10.
```
% brew install python@3.10
```
Install pipx by following these instructions.

To test your installation of pipx, close and reopen your terminal window, then type the following command:
```
% pipx --version
1.4.3
```
If the version number prints successfully, then your installation is working properly. Otherwise, try running the pipx ensurepath command again.

Install LabGym via pipx.

% pipx install --python python3.10 LabGym

Install Detectron2 in the LabGym’s virtual environment.

% pipx runpip LabGym install 'git+https://github.com/facebookresearch/detectron2.git'

Launch LabGym.
```
% LabGym
```
The GUI will take a few minutes to start up during the first launch. If the LabGym GUI shows up, you have successfully installed LabGym!
