 In this exercise we will build a simple model that can predict the carbon dioxide uptake in MOFs. The goal is to get familiar with the tools that are used for machine learning and to develop an understanding of the workflow, tricks, and pitfalls (e.g., why baselines are important). Some more of the theory can be found [in our review](https://pubs.acs.org/doi/abs/10.1021/acs.chemrev.0c00004).

 Here, you can use relatively powerful computing resources (like [GPUs](https://en.wikipedia.org/wiki/Graphics_processing_unit) and [TPUs](https://en.wikipedia.org/wiki/Tensor_Processing_Unit)) from Google for free.
 Click the "Open in Colab" button on the top, then make a copy of the notebook into your Google Drive, and run the first three cells to
 install the dependencies.
 Then you should be able to use the notebook in Colab.
