Is there a quilt.plot() equivalent function from R in python?

I am trying to simulate a GP with a Matern covariance and I want to visualize the 2D matrix. The problem is that the functions plt.imshow() and seaborn.heatmap() are not doing what quilt.plot() does. Any suggestions?

Edit: to show what I have tried

iid_data = np.random.randn(self.n_points, 1)

chol_decomp_lower = np.linalg.cholesky(covariance)
observed_data = chol_decomp_lower @ iid_data

x_coor = self.domain[:, 0].reshape(32, 32)
y_coor = self.domain[:, 1].reshape(32, 32)

colormap = observed_data.reshape(32, 32)

observed_data = np.zeros([32, 32, 3])
observed_data[:, :, 0] = x_coor
observed_data[:, :, 1] = y_coor
observed_data[:, :, 2] = iid_data.reshape(32, 32)

plt.imshow(iid_data.reshape(32, 32), cmap="hot")
plt.imshow(colormap, cmap="hot")

observed_data[:, :, 2] = colormap
plt.imshow(observed_data)

plt.pcolormesh(x_coor, y_coor, colormap)
sn.heatmap(iid_data.reshape(32, 32), cmap="YlGnBu")
sn.heatmap(colormap, cmap="YlGnBu")

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...

How to show number of registered users in Laravel based on usertype?

i'm trying to display data from the database in the admin dashboard i used this: <?php use Illuminate\Support\Facades\DB; $users = DB::table('users')->count(); echo $users; ?> and i have successfully get the correct data from the database but what if i want to display a specific data for example in this user table there is "usertype" that specify if the user is normal user or admin i want to user the same code above but to display a specific usertype i tried this: <?php use Illuminate\Support\Facades\DB; $users = DB::table('users')->count()->WHERE usertype =admin; echo $users; ?> but it didn't work, what am i doing wrong? source https://stackoverflow.com/questions/68199726/how-to-show-number-of-registered-users-in-laravel-based-on-usertype

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() ...
