Executing a python script using Flask [duplicate]
This question already has an answer here:
Flask view raises TypeError: 'bool' object is not callable
1 answer
I trying to executing a Python script through Flask.
I wrote below python code to execute another python script.
from flask import Flask
import subprocess
app = Flask(__name__)
@app.route("/")
def home():
subprocess.call("/home/tech/Downloads/labelme-master/labelme/main.py 1", shell=True)
#return "Hello, World!"
if __name__ == "__main__":
app.run(debug=True)
But unfortunately when I run above python code and check the 127.0.0.1:5000 It's giving this error in browser :
TypeError: The view function did not return a valid response. The function either returned None or ended without a return statement.
Any solution?
My ultimate goal is to open a python script via HTML page's Button.

As a response, you have to return from the function. so you can do like this
from flask import Flask
import subprocess
app = Flask(__name__)
@app.route("/")
def home():
subprocess.call("python /home/tech/Downloads/labelme-master/labelme/main.py 1", shell=True)
return "ok"
if __name__ == "__main__":
app.run(debug=True)
