Are you trying to use the pix2pix library? Try creating a file named "__init__.py" in the directory.

The file data_loader.py should be in the same directory.

It appears you are also working through the (fantastic) Manning series "GANs in Action". Your code appears to be the final section, on CycleGANs. The authors note that the data_loader is provided in their GitHub repo for the chapter. Check out their workbook here: https://github.com/GANs-in-Action/gans-in-action/blob/master/chapter-9/Chapter9_CycleGAN.ipynb
