how to tackle numpy warnings

i am trying to generate a plot with annotations, the issue is that i have for each x value multiple y values correspond to it, so in order to keep x and y similar in size, i wrote the following:

 x = [-2,-1,0,1,2]
    y = [(22.8,19.6),(8.9,13.7,14.7),(1.9,-1.8),(-3,-5.9,-13.4),(-5.7,-6.8)]

however, i am constantly getting the follwoing warning:

VisibleDeprecationWarning: Creating an ndarray from ragged nested sequences (which is a list-or-tuple of lists-or-tuples-or ndarrays with different lengths or shapes) is deprecated. If you meant to do this, you must specify 'dtype=object' when creating the ndarray. _data = np.array(data, dtype=dtype, copy=copy,

my full code:

import matplotlib.pyplot as plt
import numpy as np
x = [-2,-1,0,1,2]
y = [(22.8,19.6),(8.9,13.7,14.7),(1.9,-1.8),(-3,-5.9,-13.4),(-5.7,-6.8)]
custom_annotations = ["K464E", "K472E", "K464", "M155E", "K472", "M155A", "Q539A", "M155R", "D244A", "E247A", "E247R", "D244K"]
plt.scatter(x, y, marker="o")
for i, txt in enumerate(custom_annotations):
    plt.annotate(txt, (x[i], y[i]))
plt.savefig("1.png")

Why is my reports service not connecting?

I am trying to pull some data from a Postgres database using Node.js and node-postures but I can't figure out why my service isn't connecting. my routes/index.js file: const express = require('express'); const router = express.Router(); const ordersCountController = require('../controllers/ordersCountController'); const ordersController = require('../controllers/ordersController'); const weeklyReportsController = require('../controllers/weeklyReportsController'); router.get('/orders_count', ordersCountController); router.get('/orders', ordersController); router.get('/weekly_reports', weeklyReportsController); module.exports = router; My controllers/weeklyReportsController.js file: const weeklyReportsService = require('../services/weeklyReportsService'); const weeklyReportsController = async (req, res) => { try { const data = await weeklyReportsService; res.json({data}) console...

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() ...
