无法在python中使用Flasgger时出现laod API定义错误

Question

​

​

我正在使用python中的Flasgger和Flask为我的机器学习模型创建一个API。

在运行我的API文件后，我得到以下错误：‘无法加载API文档。获取错误内部服务器错误/ apispex_1.json

下面是我的代码：

import pickle
from flask import Flask, abort, jsonify, request
import numpy as np
import pandas as pd
from flasgger import Swagger 

with open('./im.pkl', 'rb') as model_file:
    model = pickle.load(model_file)

app = Flask(__name__)
swagger = Swagger(app)

@app.route('/predict')
def predict1():
 """Example
    ---
    parameters:
        -name: Days
         in: query
         type= number
         required: true
         --
         --
         --
   """
 Days = request.args.json('Days')
prediction = model.predict(np.array([[Days]]))
return str(prediction)

if __name__ == '__main__':
    app.run(port=5000, debug=True)

您在文档字符串描述中遇到错误：

@app.route('/predict')
def predict1():
 """Example
    ---
    parameters:
        - name: Days
          in: query
          type: integer
          required: true
   """

只需将type= number替换为type: integer
