amazon-web-services - 使用 AWS SageMaker create-training-job 命令：输入错误

Question

我正在尝试使用 AWS sagemaker cli 运行 create-training-job 命令。这是我的命令：

aws sagemaker create-training-job \
--training-job-name $(DEPLOYMENT_NAME)-$(BUILD_ID) \
--hyper-parameters file://sagemaker/hyperparameters.json \
--algorithm-specification TrainingImage=$(IMAGE_NAME),\
TrainingInputMode="File" \
--role-arn $(ROLE) \
--input-data-config ChannelName=training,DataSource={S3DataSource={S3DataType=S3Prefix,S3Uri=$(S3_INPUT),S3DataDistributionType=FullyReplicated}},ContentType=string,CompressionType=None,RecordWrapperType=None \
--output-data-config S3OutputPath=$(S3_OUTPUT) \
--resource-config file://sagemaker/train-resource-config.json \
--stopping-condition file://sagemaker/stopping-conditions.json 

这是错误：

Parameter validation failed:
Invalid type for parameter InputDataConfig[0].DataSource.S3DataSource, value: S3DataType=S3Prefix, type: <type 'unicode'>, valid types: <type 'dict'>
Invalid type for parameter InputDataConfig[1].DataSource.S3DataSource, value: S3Uri=s3://hs-machine-learning-processed-production/inbound-autotag/data, type: <type 'unicode'>, valid types: <type 'dict'>
Invalid type for parameter InputDataConfig[2].DataSource.S3DataSource, value: S3DataDistributionType=FullyReplicated, type: <type 'unicode'>, valid types: <type 'dict'>
make: *** [train] Error 255

错误发生在--input-data-config标志上。我正在尝试使用速记语法，以便可以注入一些变量（大写单词）。哈尔普！

因此，您的输入配置格式不正确。在此处查看示例 json： https ://docs.aws.amazon.com/sagemaker/latest/dg/API_CreateTrainingJob.html

# look at the format of input-data-config, it is a dictionary
