i tried this code:

import torch

def check_cuda():
    # Check if CUDA is available
    if torch.cuda.is_available():
        print("CUDA is available.")

        # Print CUDA version
        cuda_version = torch.version.cuda
        print(f"CUDA version: {cuda_version}")

        # Print GPU information
        gpu_count = torch.cuda.device_count()
        for i in range(gpu_count):
            gpu_name = torch.cuda.get_device_name(i)
            print(f"GPU {i + 1}: {gpu_name}")

    else:
        print("CUDA is not available.")

if __name__ == "__main__":
    check_cuda()

and i got CUDA is not available.

it got fixed by installing the latest version of pytorch with it's respective cuda version, buy now i get this error:
