OSError: [WinError 10049] The requested address is not valid in its context

when I try to initialize a python folder flask_demo.py:
import os
from multiprocessing.managers import BaseManager
from flask import Flask, request, jsonify, make_response
from flask_cors import CORS
from werkzeug.utils import secure_filename
app = Flask(name)
CORS(app)
initialize manager connection
NOTE: you might want to handle the password in a less hardcoded way
manager = BaseManager(('', 5602), b'password')
manager.register('query_index')
manager.register('insert_into_index')
manager.register('get_documents_list')
manager.connect()
@app.route("/query", methods=["GET"])
def query_index():
global manager
query_text = request.args.get("text", None)
if query_text is None:
return "No text found, please include a ?text=blah parameter in the URL", 400
response = manager.query_index(query_text)._getvalue()
response_json = {
"text": str(response),
"sources": [{"text": str(x.source_text),
"similarity": round(x.similarity, 2),
"doc_id": str(x.doc_id),
"start": x.node_info['start'],
"end": x.node_info['end']
} for x in response.source_nodes]
}
return make_response(jsonify(response_json)), 200
@app.route("/uploadFile", methods=["POST"])
def upload_file():
global manager
if 'file' not in request.files:
return "Please send a POST request with a file", 400
filepath = None
try:
uploaded_file = request.files["file"]
filename = secure_filename(uploaded_file.filename)
filepath = os.path.join('documents', os.path.basename(filename))
uploaded_file.save(filepath)
if request.form.get("filename_as_doc_id", None) is not None:
manager.insert_into_index(filepath, doc_id=filename)
else:
manager.insert_into_index(filepath)
except Exception as e:
# cleanup temp file
if filepath is not None and os.path.exists(filepath):
os.remove(filepath)
return "Error: {}".format(str(e)), 500
# cleanup temp file
if filepath is not None and os.path.exists(filepath):
os.remove(filepath)
return "File inserted!", 200
@app.route("/getDocuments", methods=["GET"])
def get_documents():
document_list = manager.get_documents_list()._getvalue()
return make_response(jsonify(document_list)), 200
@app.route("/")
def home():
return "Hello, World! Welcome to the llama_index docker image!"
if name == "main":
app.run(host="0.0.0.0", port=5601)
I get this error in the terminal:

can someone help me!
Did you launch the index_server.py before running the flask server?
No, I ran flask_demo.py first
Try launching index_server.py first (run it in another terminal or in the background)
Then launch the flask demo. Should work!
even initializing the index_server.py folder first, it stays for more than an hour and does not output this information in the terminal: python index_server.py
initializing index...
server started...
Right, that means it's running 💪
So then if you open another terminal and run python ./flask_demo.py then the flask demo will work
The flask server connects to the index server.
So the index server has to be running in order to launch the flask server
I get this error when initializing index, I think it's version compatibility:
python index_server.py
initializing index...

Try deleting the "./savex_index" folder, maybe something got corrupted from before
ok i will do that
OK! One last issue, and I think it's because of windows
In flask_demo.py near the bottom, change "0.0.0.0" to "localhost"
I'm using windows 10, and it seems to me that the problem could be this, because even so the initialization code didn't work
I will try on another computer
Hmm sounds good! Another option for windows is trying "127.0.0.1", I forget which ip address works with windows lol
keeps giving the same error
what operating systems are used?
I personally use WSL Ubuntu on windows for everything.
Even "127.0.0.1" does not work?
yes even using "127.0.0.1", it's not working
Ah I overlooked one thing,
So, change flask_demo.py to have app.run(host="127.0.0.1", port=5601)
Then, in addition, change the top of flask_demo.py to have manager = BaseManager(('127.0.0.1', 5602), b'password')
Then, in index_server.py, modify the manager to be the same: manager = BaseManager(('127.0.0.1', 5602), b'password')
I just tested in powershell, seems to work
I did it and it worked very well, I am very happy for your help, leave your social networks to me, I live in Angola (Africa)
Perfect! Glad it works now 👍🏻
