" DenseToSparseBatchDataset“device_type："CPU”用于未知操作:DenseToSparseBatchDataset

Question

经过大量修改后，tensorflow从源代码中构建并安装到Python3.5中(它似乎不喜欢3.6)，现在一个Keras程序在笔记本上运行，没有像以前那样受到tensorflow的任何抱怨，有些东西没有安装到标准。但是，它似乎确实大量使用CPU：

GPU轻描淡写：

从jupyter内核输出中的消息来看，它似乎已经有意识地决定使用CPU而不是GPU：

所有这些包含device_type: "CPU"的行的含义是什么？

有没有人知道这是否正常，或者这可能是某个地方缺少依赖关系的迹象？

自那以后，这种变化一直是倒回，警告消息不应该再被打印出来。
