minor change for better code implementation

• Maybe you can push VAE-Pytorch/utils to this repo too.
• ModuleNotFoundError: No module named 'dataset' pops up. It happened in VAE code too. So to include
  import sys sys.path.append("./")

When do you see the 'ModuleNotFoundError' ?

[akansh12]

while running
python tools/train_gan.py

[explainingai-code]

Yeah.. I suspected that. It should be run via python -m tools.train_gan which ensures the import correctly and not python tools/train_gan.py . Same for VAE .
