Please provide as much information as possible. At least, this should include a description of your issue and steps to reproduce the problem. If possible please provide a summary of what steps or workarounds you have already tried, and any docs or articles you found (un)helpful.

Problem you have encountered:
Vision API always display the same "topicality" and "score" response values when using "LABEL_DETECTION" feature.

What you expected to happen:
The API should retrieve different values for each image score, based on the https://cloud.google.com/vision/docs/reference/rest/v1/images/annotate#entityannotation documentation

Steps to reproduce:
API request:
Header:
http://vision.googleapis.com/v1/images:annotate?key=[API_KEY]

Body:
{
  "requests": [
    {
      "features": [
        {

        }
      ],
      "image": {
        "source": {
          "imageUri": "gs://[BUCKET_NAME]/[FILE_NAME]"
        }
      }
    }
  ]
}

API response code:
{
 "responses":[
  {
   "labelAnnotations":[
    {
     "mid": "/m/01fdzj",
     "description": "tower",
     "score": 0.9670615,
