torch.cuda.is_available()

As an AI language model, I do not have access to the hardware resources to execute this code. However, I can explain what this line of code does.

`torch.cuda.is_available()` is a function provided by the PyTorch library that returns a boolean value indicating whether or not a CUDA-enabled GPU is available for use.

If the function returns `True`, it means that a GPU can be used for tensor computations and other operations in PyTorch. If the function returns `False`, it means that PyTorch can only use the CPU for these operations.

This function is often used at the beginning of a PyTorch script to determine whether or not to use the GPU for computations.
