如何在opencv python3中读取boto3文件对象

Question

I am trying to read the AWS S3 presigned uri file with open-CV. But the read parameter is of NoneType. How to read the boto3 file_obj in opencv and process further?

import cv2
import boto3

s3Client = boto3.client('s3')
file_path = s3Client.generate_presigned_url('get_object', Params = {'Bucket': 
'www.mybucket.com', 'Key': 'hello.txt'}, ExpiresIn = 100)
img = cv2.imread(file_path)

But it is reading the file as <class 'NoneType'> . But I need it to be read by the cv2.

Answer 1

import urllib2

response = urllib2.urlopen(file_path)
image = response.read()
img = cv2.imread(image)

can you please try this
