API calls for AWS is not being mocked even though moto is being used

[krtkvrm]

I have referred #1926, #1793 and #2118 before opening this issue.

I am getting the error for ecr:

botocore.exceptions.ClientError: An error occurred (UnrecognizedClientException) when calling the DescribeRepositories operation: The security token included in the request is invalid.

and, I am also getting:

/home/x/proj/lib/python3.6/site-packages/requests/__init__.py:80: RequestsDependencyWarning: urllib3 (1.23) or chardet (3.0.4) doesn't match a supported version!
  RequestsDependencyWarning)
Performing system checks...

I am getting this error only when I add moto to requirements.txt
If I run pip install moto after running pip install -r requirements.txt, I am not getting both of the errors.
boto3==1.9.88
botocore==1.12.0
moto==1.3.8

It is accessing aws apis are when I disconnected, I got this:

Exception Value: Could not connect to the endpoint URL: "https://ecr.us-east-1.amazonaws.com/"

Code:

@if_non_prod_aws_mocker(mock_ecr)
@if_non_prod_aws_mocker(mock_sts)
def get_aws_credentials_for_submission(challenge, participant_team):
    repository, created = get_or_create_ecr_repository(
        ecr_repository_name, aws_keys
    )
    # getting error on line above
    #other codes

get_or_create_ecr_repository():

def get_or_create_ecr_repository(name, aws_keys):
    repository, created = None, False
    client = get_boto3_client("ecr", aws_keys)
    try:
        response = client.describe_repositories(
            registryId=aws_keys.get("AWS_ACCOUNT_ID"), repositoryNames=[name]  # Error is pointing at this line
        )
        repository = response["repositories"][0]
    except ClientError as e:
        if e.response["Error"]["Code"] == "RepositoryNotFoundException" or\
           e.response["Error"]["Code"] == "400":
            response = client.create_repository(repositoryName=name)
            repository = response["repository"]
            created = True
        else:
            logger.exception(e)
    return (repository, created)

@if_non_prod_aws_mocker:

        if not (settings.DEBUG or settings.TEST):
            return func
