Cannot download objectnet-1.0-beta test set

[vishaal27]

Hey, I am unable to download the objectnet test set -- is the server down for some reason?

I was able to fix it with the google client instead of the default vasa one!

def key_exists(bucket, key):
    # Return true if a key exists in s3 bucket
    # TODO: return None from the get functions if the key doesn't exist?
    #       (this would avoid one round-trip to S3)
    client = get_s3_client_google()
    print(client._endpoint.host)
    try:
        client.head_object(Bucket=bucket, Key=key)
        return True
    except botocore.exceptions.ClientError as exc:
        if exc.response['Error']['Code'] != '404':
            raise
        return False
    except:
        raise

instead of

def key_exists(bucket, key):
    # Return true if a key exists in s3 bucket
    # TODO: return None from the get functions if the key doesn't exist?
    #       (this would avoid one round-trip to S3)
    client = get_s3_client()
    print(client._endpoint.host)
    try:
        client.head_object(Bucket=bucket, Key=key)
        return True
    except botocore.exceptions.ClientError as exc:
        if exc.response['Error']['Code'] != '404':
            raise
        return False
    except:
        raise

in src.mldb.s3_utils.py. This issue was helpful for this: #9
