error in webserver

error al execute command: ´´python blackbird.py --web´´
Hi!
Please comment with a screenshot that shows the end of the error message.
Thanks!
The webserver is started on http://127.0.0.1:5000, the error says that this address is already in use, verify if there is any other service running in this address.
If you can't stop that other service, you will need to change the port that the webserver is started, to do that go to line 40 of webserver.py and overwrite it with this:
app.run(host='0.0.0.0', port=5001)This should fix your problem.
It might be worth putting in an argument that allows users to specify a specific port so that this issue doesn't happen again. Would this be something I could work on and possibly contribute to this project?
Hi Tjhasan!
Of course, any help is welcome.
So I've been hammering away at this for a bit and I realized that, if the --web argument is called and the command = subprocess.run() function is executed, the blackbird.py file is run a 2nd time. This sets all of the argparser args back to default.
Is there a reason why this is happening? I ask because if we can prevent it from running twice, then creating a dynamic port can just be added as an argument to argparser.
Awesome, in that case i'll go ahead and implement that right now.
Hi Manuelq059, just changed the default port to 9797, this may fix this issue for now.
Hi,
i can't start the web-version.
