 The datasets that we are using are available online:
 - [BioSR](https://github.com/qc17-THU/DL-SR), the data that we are using has been transformed to .npy files. You can also obtain the data [here](https://drive.google.com/drive/folders/1ZMLAZo4AGX4QASEyd3MGf8LE2B_Bne04?usp=sharing). To generate the training .npz you need to join the parts with
