Dynamically Provision iot Device With Azure dps - Unexpected Failure. Python sdk

I am dynamically provision an iot device using the python azure-iot-device python package. I am using v2 and not 3.0.0b2. I can't even get that to compile.

Here's my python code trying to provision a device:

import asyncio
import os

from azure.iot.device.aio import (
    ProvisioningDeviceClient,
)
from dotenv import load_dotenv
load_dotenv(dotenv_path=".env")

CONNECTION_STRING = os.getenv("IOTHUB_DEVICE_CONNECTION_STRING")
ID_SCOPE = os.getenv("PROVISIONING_IDSCOPE")
REGISTRATION_ID = os.getenv("PROVISIONING_REGISTRATION_ID")
SYMMETRIC_KEY = os.getenv("PROVISIONING_SYMMETRIC_KEY")
PROVISIONING_HOST = os.getenv("PROVISIONING_HOST")
# PROVISIONING_SHARED_ACCESS_KEY = os.getenv("PROVISIONING_SHARED_ACCESS_KEY")

async def main():
    print("Starting multi-feature sample")
    provisioning_device_client = ProvisioningDeviceClient.create_from_symmetric_key(
        provisioning_host=PROVISIONING_HOST,
        registration_id=REGISTRATION_ID,
        id_scope=ID_SCOPE,
        symmetric_key=SYMMETRIC_KEY,
    )
    provisioning_device_client.provisioning_payload = "<Your Payload>"
    provisioning_result = None
    try:
        provisioning_result = await provisioning_device_client.register()
    except Exception as e:
        print(f"an error occurred provisioning the device -- {e}")
    finally:
        print(f"result -- {provisioning_result}")
  
if __name__ == "__main__":
    try:
        asyncio.run(main())
    except KeyboardInterrupt:
        # Exit application because user indicated they wish to exit.
        # This will have cancelled `main()` implicitly.
        print("User initiated exit. Exiting.")

The symmetric key is derived by using the enrollment group master key to compute an HMAC-SHA256 of the registration ID for the device. I simply followed the "Derive a Device Key" section in this guide -- https://learn.microsoft.com/en-us/azure/iot-dps/how-to-legacy-device-symm-key?tabs=linux&pivots=programming-language-python#derive-a-device-key

I keep getting 'Unexpected Failure' error. The code is so little that there's almost nothing to debug. I believe I followed the steps closely in setting up my iot hub and dps. Please let me know any suggestions

The number of nodes and edges I calculated manually and by a method provided by networkx library dont match

I am trying to analyse a graph using networkx library in Python. I have implemented a function that returns the nodes and edges of that graph. After that I counted the number of nodes and edges by implementing the len() function for nodes and edges, which gave me 17 for both nodes and edges. However, when I used the method graph.number_of_nodes() of networkx library it gave me 53. My code: import pandas as pd import networkx as nx import matplotlib.pyplot as plt header_list = ["a","b","w"] E =pd.read_csv("aves-barn-swallow-contact-network.edges",sep=" ",header= None,names=header_list) # print(E.head()) # prints first few rows of the csv file G = nx.from_pandas_edgelist(E,"a","b",["w"]) nx.draw(G) plt.show() class GraphAnalyse: #finding nodes and edges def nodeEdge(self,Graph): nodes = Graph.nodes() edges = Graph.edges() ...
