Arrays view函数未返回有效响应。函数返回None或结束时没有返回语句
我尝试使用flask和numpy返回函数np.correlate的结果Arrays view函数未返回有效响应。函数返回None或结束时没有返回语句,arrays,numpy,flask,Arrays,Numpy,Flask,我尝试使用flask和numpy返回函数np.correlate的结果 from flask import Flask import numpy as np app = Flask(__name__) @app.route("/") def corelation(): # 1 2 3 8 9 7 3 12 65 45 26 33 firstArray = np.loadtxt("C:\\Users\\user\\source\\repos\\C

我收到以下消息：view函数未返回有效响应。函数要么返回None，要么不返回return语句而结束如果只需要np.array的文本表示，最简单的方法是
from flask import make_response
...
corr = np.correlate(firstArray,secondArray, 'full')
response = make_response(str(corr), 200)
response.mimetype = 'text/plain'
return response
print（corr）
