应用错误收集

所以我在我的笔记本电脑上安装了Tensorflow for Python 3.5，这是一台托管Nvidia Geforce Pascal GPU的Windows机器。我还安装了CUDA并下载了cuDNN并将其添加到PATH变量中。我的tensorflow代码确实编译，但如果我监视我的GPU，我可以看到，它不会计算任何东西，而是我的CPU正在完成整个工作。我还在控制台中得到一个输出，确认已检测到GPU：

有人可以向我解释一下吗？

编辑：好的，似乎，我没有看到使用准确的用法。 GPU实际上是使用的，但仅限于小峰值。大部分工作仍由CPU完成。我正在运行一个有3个卷积和2个完全连接层的CNN。但这不是正确的吗？ ![GPU Usage

使用GPU进行Tensorflow，检测到右GPU但不使用它进行计算
