Aws Transribe无法在boto3中启动_Transcription_JOB而没有LanguageCode

Question

我在s3中有一个音频文件。

mediaFileUri = 's3://'+ bucket_name+'/'+prefixKey

transcribe_client = boto3.client('transcribe')

response = transcribe_client.start_transcription_job(
    TranscriptionJobName="abc",
    IdentifyLanguage=True,
    Media={
        'MediaFileUri':mediaFileUri
    },
)

然后我得到这个错误：

{
  "errorMessage": "Parameter validation failed:\nMissing required parameter in input: \"LanguageCode\"\nUnknown parameter in input: \"IdentifyLanguage\", must be one of: TranscriptionJobName, LanguageCode, MediaSampleRateHertz, MediaFormat, Media, OutputBucketName, OutputEncryptionKMSKeyId, Settings, ModelSettings, JobExecutionSettings, ContentRedaction",
  "errorType": "ParamValidationError",
  "stackTrace": [
    "  File \"/var/task/app.py\", line 27, in TranscribeSoundToWordHandler\n    response = response = transcribe_client.start_transcription_job(\n",
    "  File \"/var/runtime/botocore/client.py\", line 316, in _api_call\n    return self._make_api_call(operation_name, kwargs)\n",
    "  File \"/var/runtime/botocore/client.py\", line 607, in _make_api_call\n    request_dict = self._convert_to_request_dict(\n",
    "  File \"/var/runtime/botocore/client.py\", line 655, in _convert_to_request_dict\n    request_dict = self._serializer.serialize_to_request(\n",
    "  File \"/var/runtime/botocore/validate.py\", line 297, in serialize_to_request\n    raise ParamValidationError(report=report.generate_report())\n"
  ]
}

如果出现此错误，意味着必须指定languagecode，并且IdentifyLanguage是无效参数。

100%确定音频文件存在于S3中。但是如果没有languagecode，它就不起作用，并且IdentifyLanguage参数是未知参数

sam local invoke MyHandler -e lambda\TheDirectory\event.json

我看着Aws转录的这些文档：

https://docs.aws.amazon.com/transcranbe/latest/dg/api_starttranscranptionjob.html

boto3的文档：

我错过了什么？对此有什么想法吗？我该怎么办？

更新：

我一直在网上搜索并询问了几个人，我想我应该先建立一个函数容器，让SAM把boto3打包到容器中。

cdk synth --no-staging > template.yaml

sam build --use-container
sam local invoke MyHandler78A95900 -e lambda\TheDirectory\event.json

不带languagecode

IdentiyLanguage=true

检查您是否正在使用最新的boto3版本。

boto3.__version__  
'1.16.5'

我试过了，很管用。

import boto3

transcribe = boto3.client('transcribe')
response = transcribe.start_transcription_job(TranscriptionJobName='Test-20201-27',IdentifyLanguage=True,Media={'MediaFileUri':'s3://BucketName/DemoData/Object.mp4'})

print(response)
{
    "TranscriptionJob": {
        "TranscriptionJobName": "Test-20201-27",
        "TranscriptionJobStatus": "IN_PROGRESS",
        "Media": {
            "MediaFileUri": "s3://BucketName/DemoData/Object.mp4"

    },
