How to do it...

There are two ways to install Gym. The first one is to use pip, as follows:

pip install gym

For conda users, remember to install pip first in conda using the following command before installing Gym using pip:

conda install pip

This is because Gym is not officially available in conda as of early 2019.

Another approach is to build from source:

1. First, clone the package directly from its Git repository:

git clone https://github.com/openai/gym

2. Go to the downloaded folder and install Gym from there:

cd gympip install -e .

And now you are good to go. Feel free to play around with gym.

3. You can also check the available gym environment by typing the following lines of code:

>>> from gym import envs>>> print(envs.registry.all()) ...
