向tensorflow服务模型进行卷曲查询以预测API中断

Question

我正在使用本教程TensorFlow Serving with Docker进行查询

curl -d '{"instances": [1.0, 2.0, 5.0]}' \
    -X POST http://localhost:8501/v1/models/half_plus_two:predict

返回

`C:\WINDOWS\system32>curl -d '{"instances": [1.0, 2.0, 5.0]}' -X POST http://localhost:8501/v1/models/half_plus_two:predict

curl: (3) [globbing] bad range in column 2
curl: (6) Could not resolve host: 2.0,
curl: (3) [globbing] unmatched close brace/bracket in column 4
{ "error": "JSON Parse error: Invalid value. at offset: 0" }`

但是docker运行正常。

    PS E:\git_portable> docker run -t --rm -p 8501:8501 -v "E:\git_portable\serving\tensorflow_serving\servables\tensorflow\testdata\saved_model_half_plus_two_cpu:/models/half_plus_two" -e MODEL_NAME=half_plus_two tensorflow/serving

当我向本地主机运行普通curl时，它会返回正常。

C:\WINDOWS\system32>curl http://localhost:8501/v1/models/half_plus_two
{
 "model_version_status": [
  {
   "version": "123",
   "state": "AVAILABLE",
   "status": {
    "error_code": "OK",
    "error_message": ""
   }
  }
 ]
}

我在这里做错了什么？

我们有同样的问题。这里..

Windows的cmd不支持带单引号的字符串。使用“和用\“转义内部的。

在此链接中：Windows: curl with json data on the command line

现在，

`C:\WINDOWS\system32>curl -d "{\"instances\": [1.0, 2.0, 5.0]}" \
-X POST http://127.0.0.1:8501/v1/models/half_plus_two:predict

{
    "predictions": [2.5, 3.0, 4.5
    ]
}`
