tensorflow,pytorch,paddle 测试GPU是否可用

1、tensorflow

import tensorflow as tf
print(tf.test.is_gpu_available())
print(tf.config.list_physical_devices('GPU'))

2、pytorch

import torch
print(torch.cuda.is_available())
print(torch.Tensor(5, 3).cuda())

3、paddlepaddle

import paddle
paddle.fluid.install_check.run_check()

paddle.fluid.is_compiled_with_cuda()
