调整图像大小时出现逻辑错误

我正在使用下面的代码,该代码负责使用python的pillow库更改图像分辨率。我正在aws lambda上部署代码。代码运行良好,但在调整大小时存在一个简单的逻辑缺陷。本规范的作用如下: 1、将图像上传到S3 bucket 代码将图像大小调整为两个不同的维度,并将其上载到不同的bucket。

但是代码以相同的维度上传了这两幅图像,我不明白为什么

from __future__ import print_function
import boto3
import os
import sys
import uuid
from PIL import Image
import PIL.Image

s3_client = boto3.client('s3')

def resize_image_DOG(image_path, resized_path):
    with Image.open(image_path) as image:
        dim=(3840,2160)
        image.resize(dim)
        image.save(resized_path)

def resize_image_CAT(image_path, resized_path):
    with Image.open(image_path) as image:
        dim=(1920,1080)
        image.resize(dim)
        image.save(resized_path)


def handler(event, context):
    for record in event['Records']:
        bucket = record['s3']['bucket']['name']
        key = record['s3']['object']['key'] 
        download_path = '/tmp/{}{}'.format(uuid.uuid4(), key)
        upload_path_1 = '/tmp/resized-{}{}'.format('test1',key)
        upload_path_2 = '/tmp/resized-{}{}'.format('test2',key)

        s3_client.download_file(bucket, key, download_path)

        resize_image_DOG(download_path, upload_path_1)
        resize_image_CAT(download_path, upload_path_2)

        s3_client.upload_file(upload_path_1, '{}resized'.format(bucket), key+'xxxhdpi-3840*2160'+'.png')

        s3_client.upload_file(upload_path_2, '{}resized'.format(bucket), key+'xxxhdpi-1920*1080'+'.png')

上载到已调整大小的bucket的2个已调整大小的图像的尺寸相同,即仅第一个resize\u image\u DOG尺寸(3340x2160),但名称正确,请帮助
