输入实例不是JSON格式 [英] Input instances are not in JSON format

问题描述

我正在使用Google的公共模板和位于此处

I'm practicing GCP ML engine using Google's public templates and examples located here

我在示例住房回归" 本地中运行了代码之后，模型已成功生成.

After I ran the code in the example "housing-regression" LOCALLY, the model was successfully generated.

但是，在预测中，出现了错误

However, in prediction, an error was raised

错误:(gcloud.ml-engine.local.predict)输入实例不是JSON格式.

ERROR: (gcloud.ml-engine.local.predict) Input instances are not in JSON format.

有关详细信息，请参见"gcloud ml-engine Forecast --help".

See "gcloud ml-engine predict --help" for details.

我运行的代码在local-train.sh

gcloud ml-engine local predict --model-dir=${MODEL_LOCATION} --json-instances=data/new-data.json

有人有同样的问题吗?我是在某个地方犯了错误，还是可能错过了一些信息?

Does anyone have the same problem? Did I make a mistake somewhere or is there some information I may have missed?

注:

NOTES:

1. 此代码使用已安装的GCP SDK在Mac上本地运行
2. 我检查了该文件，它确实是JSON文件.

推荐答案

对于在线预测，json需要每行一个实例.因此，请尝试删除漂亮的格式...

For online prediction, the json needs to be one instance per line. So try removing the pretty formatting ...
