Question

我正在尝试使用gcloud ai-platform命令行工具从本地模型中获得预测，但是我收到一个错误消息“错误：（gcloud.ai-platform.local.predict）某些地方真的出了问题；我们在您的PATH上找不到有效的Python可执行文件”

命令

gcloud ai-platform local predict --model-dir={MODEL_PATH} --json-instances={JSON IMAGE} --verbosity debug

给出错误

DEBUG: Running [gcloud.ai-platform.local.predict] with arguments: [--json-instances: "C:\Users\umara\Desktop\DLOCTseg\Normal Image.json", --model-dir: "C:\Users\umara\Desktop\DLOCTseg\export\v1", --verbosity: "debug"]

ERROR: (gcloud.ai-platform.local.predict) Something has gone really wrong; we can't find a valid Python executable on your PATH.

但是PATH环境变量包含有效的python。（我已经尝试了两件事。使用我的系统python 3.6版运行命令，或者在包含python 2.7的anaconda虚拟环境中运行命令，都给出相同的错误）

echo %PATH%产生：

和echo %CLOUDSDK_PYTHON%产生

C:\Program Files\Python36\python.exe

我也尝试过卸载并重新安装云SDK，但这并不能解决问题。有人可以启发我解决这个问题。谢谢

此命令[1]要求在本地安装TensorFlow SDK，并应使用捆绑的python安装来运行Cloud SDK。
