+* Create a folder named `dsprites` in `ar-vae/data/` directory. Clone [this](https://github.com/deepmind/dsprites-dataset) repository and copy its contents to the created `dpsrites` folder.
+* Download the `.zip` file linked [here](https://drive.google.com/file/d/1yvkm0ebyG3XAZ97ZRaiumFUAmlXkY1bA/view?usp=sharing). Unzip it and place the `datasets` and `folk_raw_data` folders in the `ar-vae/data/` directory.
