Question

我正在运行TensorFlow附带的deepdream.ipnyb示例。第render_naive(T(layer)[:,:,:,channel])行给了我CopyCPUTensorToGPU: GPU Memcpy failed。

一种可能性是，来自TensorFlow HEAD的笔记本电脑与我最近发布的TensorFlow安装电脑不匹配。

但如果是这种情况，我会期望更多的人有同样的问题。这似乎是一个非常罕见的错误，因为CopyCPUTensorToGPU: GPU Memcpy failed的{{3}}会产生总共5个结果。

第二种可能性是，这是我运行的特定机器的问题，EC2的g2.2xlarge。

Stack：EC2的g2.2xlarge机器，Python 2，Jupyter
