torch.manual_seed(args.seed)

This line of code sets the random seed for PyTorch's random number generator. This ensures that the same random numbers will be generated every time the code is run with the same seed. Setting a seed is useful for reproducibility and debugging purposes.
For example, if you are training a deep learning model and you want to compare the results of different experiments, you can ensure that each experiment uses the same random initialization by setting the same seed. This way, any differences in the results can be attributed to changes in the model or the data, rather than random initialization.
In the code snippet provided, `args.seed` is a command line argument that specifies the random seed to use. By setting the seed with `torch.manual_seed(args.seed)`, PyTorch's random number generator will use the specified seed for generating random numbers.
