如何确认NVIDIA K2200和Tensorflow-GPU正常工作？

我刚在我的Windows 10电脑上安装了两个Nvidia K2200 GPU，CUDA软件和CuDNN软件。我通过遵循this堆栈溢出的答案去检查一切是否正常，但是我收到了一条带有一堆警告的大消息。我不知道如何解释它。消息是否意味着某些东西和我的TensorFlow/Keras代码不起作用？如何确认NVIDIA K2200和Tensorflow-GPU正常工作？

它看起来像大多数只是警告（“W”）或信息（“我”）。我不认为他们是错误的，但我不是专家。 – raphael75

检查显卡的负载？ – Paddy

@Paddy我该怎么做？你能推荐一个程序吗？ – user1367204

你可以尝试添加负载（例如训练一些模型），并检查“NVIDIA-SMI”从终端，同时它的工作 - 它应该表现出你的GPU利用率。

如果您使用默认安装文件夹，您应该可以在Windows上找到它： C：\ Program Files \ NVIDIA Corporation \ NVSMI – niklascp
