Question

我正在使用tensorflow服务来服务基于YOLO_V3 keras的模型

现在，一切正常，但只是预测我得到的是一个np数组，如何解码为实际的类

这是我正在使用的功能

import argparse
import json

import numpy as np
import requests
from keras.preprocessing import image

# Argument parser for giving input image_path from command line
ap = argparse.ArgumentParser()
ap.add_argument("-i", "--image", required=True,
                help="path of the image")
args = vars(ap.parse_args())

image_path = args['image']
# Preprocessing our input image
img = image.img_to_array(image.load_img(image_path, target_size=(224, 224))) / 255.

# this line is added because of a bug in tf_serving(1.10.0-dev)
img = img.astype('float16')

payload = {
    "instances": [{'input_image': img.tolist()}]
}

# sending post request to TensorFlow Serving server
r = requests.post('http://localhost:9000/v1/models/coco:predict', json=payload)
pred = json.loads(r.content.decode('utf-8'))
print(json.dumps(inception_v3.decode_predictions(np.array(pred['predictions']))[0]))

print(pred)
# Decoding the response

现在，这给出了大量词典

如何将其解码为类？

这样做会产生类不匹配错误，因为它的可可预训练模型不是imagenet

与此类似的解码功能是什么？

print(json.dumps(inception_v3.decode_predictions(np.array(pred['predictions']))[0]))

如何在张量流中解码预测
