How to put initial condition of ODE at a specific time point using odeint in Python? So I have y(0) = 5 as initial condition, following code works:: import numpy as np from scipy.integrate import …

This is my set of data, where I would like to fit a closed curve to, just like this post array([[ 0.3 , -0.05], [ 0.35, -0.05], [ 0.4 , -0.05], [ 0.45, -0.05], [ 0.5 , -0….

I work with geospatial images in tif format. Thanks to the rasterio lib I can exploit these images as numpy arrays of dimension (nb_bands, x, y). Here I manipulate an image that contains patches of …

I am trying to find the values that minimize a least squares function. The issue is that a solution may be valid or not in a way that cannot be given as a simple expression of the values. Instead, we …

I am using scipy differential evolution. I have to set the following linear constraints. 0

I’m working on the task of interpolating the points along the lanes in the images. A sample image with annotated points(image not from the actual dataset and spacing between the point is also not …

I’m very new to python and programming in general (This is my first programming language, I started about a month ago). I have a CSV file with data ordered like this (CSV file data at the bottom). …

def func(x,a,b): return a*x + b guess = (0.5,0.5,0.5) fit_df = df.dropna() col_params = {} for col in fit_df.columns: x = fit_df.index.astype(float).values y = fit_df[col].values …

I want to initialize 300,000 x 300,0000 sparse matrix using sklearn, but it requires memory as if it was not sparse: >>> from scipy import sparse >>> sparse.rand(300000,300000,.1) …
