In some OpenAI gym environments, there is a "ram" version. For example: `Breakout-v0` and `Breakout-ram-v0`. 

Using `Breakout-ram-v0`, each observation is an array of length 128.

**Question**: How can I transform an observation of `Breakout-v0` (which is a 160 x 210 image) into the form of an observation of `Breakout-ram-v0` (which is an array of length 128)?

My idea is to train a model on the `Breakout-ram-v0` and display the trained model playing using the `Breakout-v0` environment.
