ExpirationError(code=StatusCode.DEADLINE_EXCEEDED, details="Deadline Exceeded")

Question

我正在关注tutorial 使用 tensorflow 服务部署初始模型。我使用的是 ubuntu 16.04 和 bazel 13.0。服务器正在运行能够 ping 服务器。但是当我上传图片时，它显示以下错误

jennings@Jennings:~/serving$ bazel-bin/tensorflow_serving/example/inception_clie                                nt --server=localhost:9000 --image=./Xiang_Xiang_panda.jpg

Answer 1

当 tensorflow 服务客户端无法与服务器进行通信时会发生这种情况。或者这也可能由于网络错误而发生。如果你使用 docker 来托管你的 tensorflow 模型服务器，你需要打开容器中的端口，如下所述，

docker run --name=tensorflow_container -p 9020:9020 -it $USER/tensorflow-serving-devel

让我知道这是否有效。祝你好运。
