explainable_ai_sdk.load_model_from_ai_platform GoogleCloudPlatform误差

Question

我想部署和使用一个模型的AI平台预测与人工智能解释。所以我创建了一个模型版本：

代码:

    PROJECT_ID = 'gcloudtest-318713'
    MODEL = 'flowers' + TIMESTAMP
    REGION = 'us-west1'
    IG_VERSION = 'v_ig_3'
    
    ! gcloud beta ai-platform versions create $IG_VERSION --region=$REGION \
    --model $MODEL \
    --origin $export_path \
    --runtime-version 2.2 \
    --framework TENSORFLOW \
    --python-version 3.7 \
    --machine-type n1-standard-4 \
    --explanation-method integrated-gradients \
    --num-integral-steps 25 \
    --region $REGION

结果:

Using endpoint [https://us-west1-ml.googleapis.com/]

Explanations reflect patterns in your model, but don't necessarily reveal fundamental relationships about your data population. See https://cloud.google.com/ml-engine/docs/ai-explanations/limitations for more information.

Creating version (this might take a few minutes)......done. 

我检查了模型部署的状态，并正确地部署了模型。

代码:

# Make sure the IG model deployed correctly. State should be `READY` in the following log
! gcloud ai-platform versions describe $IG_VERSION --model $MODEL --region $REGION

结果:

Using endpoint [https://us-west1-ml.googleapis.com/]

我试着从人工智能平台加载模型。但它以以下错误失败了。

代码:

remote_ig_model = explainable_ai_sdk.load_model_from_ai_platform('gcloudtest-318713', 'flowers20210708062102', 'v_ig_3')

结果:

我解决不了这个问题。

我解决了这个问题。我的模型被部署到指定的区域，但是sdk似乎在搜索另一个区域。代码：

remote_ig_model = explainable_ai_sdk.load_model_from_ai_platform(project = 'gcloudtest-318713', mode = 'flowers20210708062102', version = 'v_ig_3', region = REGION)
