這篇文章主要介紹了大數據中常用框架的測試方法有哪些,具有一定借鑒價值,感興趣的朋友可以參考下,希望大家閱讀完這篇文章之后大有收獲,下面讓小編帶著大家一起了解一下。
TensorFlow1.x與TensorFlow2.x測試方法是一樣的,代碼如下:
import tensorflow as tf print(tf.test.is_gpu_available())
上述代碼保存為.py文件,使用需要測試環境即可運行,輸出:上面是一下log信息,關鍵的是的最后True,表示測試成功

上面是一下log信息,關鍵的是的最后True,表示測試成功。其實我們還可以發現很多GPU信息
GPU型號:name: GeForce RTX 2070 with Max-Q Design
cuda版本:Successfully opened dynamic library cudart64_100.dll(10.0)
cudnn版本:Successfully opened dynamic library cudnn64_7.dll(7.x)
GPU數目:Adding visible gpu devices: 0(1)
GPU顯存:/device:GPU:0 with 6306 MB memory(8G)
PyTorch與TensorFlow測試方法類似,都有GPU測試接口。PyTorch的GPU測試代碼如下:
import torch print(torch.cuda.is_available())
上述代碼保存為.py文件,使用需要測試環境即可運行,輸出:True,表示測試成功
True
可以看出PyTorch輸出信息簡潔很多。其實TensorFlow的log信息輸出也是可以控制的。
MXNet與PyTorch,TensorFlow測試方法不同,由于MXNet'沒有GPU測試接口(或者說筆者沒有找到)。所以MXNet的GPU測試代碼采用try-catch捕捉異常的方法來測試,代碼如下:
import mxnet as mx mxgpu_ok = False try: _ = mx.nd.array(1,ctx=mx.gpu(0)) mxgpu_ok = True except: mxgpu_ok = False print(mxgpu_ok)
上述代碼保存為.py文件,使用需要測試環境即可運行,輸出:True,表示測試成功
PaddlePaddle與TensorFlow測試方法類似,都有GPU測試接口。PyTorch的GPU測試代碼如下:
import paddle paddle.fluid.install_check.run_check()
上述代碼保存為.py文件,使用需要測試環境即可運行,輸出:Your Paddle Fluid works well on MUTIPLE GPU or CPU.,表示測試成功
