使用python3导入boto3时出现属性错误

Question

I'm trying to use aws rekognition client using boto3 on my raspberry pi, have successfully installed aws cli and have configured it also. But when i execute the following code avaialbe in aws blog,

import boto3

def detect_labels_local_file(photo):


    client=boto3.client('rekognition')

    with open(photo, 'rb') as image:
        response = client.detect_labels(Image={'Bytes': image.read()})

    print('Detected labels in ' + photo)    
    for label in response['Labels']:
        print (label['Name'] + ' : ' + str(label['Confidence']))

    return len(response['Labels'])

def main():
    photo='photo'

    label_count=detect_labels_local_file(photo)
    print("Labels detected: " + str(label_count))


if __name__ == "__main__":
    main()

I get the following error:

  import boto3
  File "/usr/local/lib/python3.7/dist-packages/boto3/__init__.py", line 16, in <module>
    from boto3.session import Session
  File "/usr/local/lib/python3.7/dist-packages/boto3/session.py", line 17, in <module>
    import botocore.session

    class SSLError(ConnectionError, requests.exceptions.SSLError):
AttributeError: module 'botocore.vendored.requests' has no attribute 'exceptions

Please help me solve it, or tell me what i'm doing wrong. Note: I'm using python 3.7.3.

This blog post should help to explain it.

You will now need to include this dependency yourself as it is no longer bundled with boto3.

For you Raspberry Pi running the following should be sufficient

pip install requests

Then add import requests to your py script
