Я работаю над AWS Sagemaker, и моя цель состоит в том, чтобы следовать этому учебнику из официальной документации Pytorch.
Исходная функция предсказания из учебника выше:
@app.route('/predict', methods=['POST'])
def predict():
if request.method == 'POST':
file = request.files['file']
img_bytes = file.read()
class_id, class_name = get_prediction(image_bytes=img_bytes)
return jsonify({'class_id': class_id, 'class_name': class_name})
Я получил эту ошибку , поэтому я добавил «GET» как метод, как упомянуто в здесь. Я также упростил свой пример до его минимального выражения:
from flask import Flask, jsonify, request
app = Flask(__name__)
@app.route('/predict', methods=['GET','POST'])
def predict():
if request.method == 'POST':
return jsonify({'class_name': 'cat'})
return 'OK'
if __name__ == '__main__':
app.run()
Я выполняю запросы со следующим кодом:
import requests
resp = requests.post("https://catdogclassifier.notebook.eu-west-1.sagemaker.aws/proxy/5000/predict",
files={"file": open('/home/ec2-user/SageMaker/cat.jpg', 'rb')})
соответственно <Response [200]>, но соответственно json () возвращает JSONDecodeError: Expecting value: line 1 column 1 (char 0) Наконец, resp.url указывает мне на страница с надписью 'OK'.
Более того, это вывод dist.content
