from flask import Flask, request, jsonify
from PIL import Image
import numpy as np
import base64
import io
import os

from backend.tf_inference import load_model, inference

os.environ['CUDA_VISIBLE_DEVICES'] = '0'

sess, detection_graph = load_model()

app = Flask(__name__)

   response = request.get_json()
   data_str = response['image']
   point = data_str.find(',')
   base64_str = data_str[point:]  # remove unused part like this: "data:image/jpeg;base64,"

   img_arr = np.array(img)

# do object detection in inference function.
   results = inference(sess, detection_graph, img_arr, conf_thresh=0.7)
   print(results)

return jsonify(results)

@app.after_request

   response.headers.add('Access-Control-Allow-Headers', 'Content-Type,Authorization')
   return response
