我在没有GPU支持的笔记本电脑上运行TensorFlow的小型网络。我现在正试图在带有GPU的Linux机器上运行它，我相信我已正确安装了所有内容。 （当然TensorFlow的“Hello，world！”示例运行。）
但是，当我尝试运行我的程序时，我收到一个以这条神秘线开头的错误：
W tensorflow/core/common_runtime/bfc_allocator.cc:275] Ran out of memory trying to allocate 4B. See logs for memory state.
真的？ 4字节？我不认为我的GPU 小。
我有两个理论，但没有真正的线索如何继续：
这是输出的较长版本：
