попробуйте запустить этот сценарий, чтобы собрать зависимость в корзине s3, а затем добавить ее в пакет развертывания лямбда-выражения.
"""
This lambda function collects python pip dependencies, and uploads them to S3 bucket
as a single tar.gz file. Example input for Lambda event:
event = {
"prefix" : "myPackage",
"saveToS3Bucket" : "my-s3-bucket",
"saveToS3Key" : "package-jwt.tar.gz",
"requirements" : [ "cryptography==2.1.3",
"PyJWT==1.5.3" ]
}
