get number of gpu python code example

Example 1: python check my gpu

from tensorflow.python.client import device_lib

def get_available_gpus():
    local_device_protos = device_lib.list_local_devices()
    return [x.name for x in local_device_protos if x.device_type == 'GPU']

Example 2: pytorch get gpu number

torch.cuda.device_count()
