Follow these steps to install OpenAI Gym, NumPy, and pandas:

1. If you have Python 3.5 installed, then you can install gym using the pip command:

$ pip install gym

In case of a Permission denied error, try to give user permissions:

$ pip install gym -U

2. For this example, we need NumPy and pandas, and you can install both using the following command:

$ python -m pip install --user numpy scipy matplotlib ipython jupyter pandas sympy nose

Alternatively, you can use the following command:

$ sudo apt-get install python-numpy python-scipy python-matplotlib ipython ipython-notebook python-pandas python-sympy python-nose

Now that your setup is complete, let's look at both algorithms in action.
