I will explain how to resolve the error TypeError: Cannot perform reduce with flexible type that may occur when using NumPy functions on arrays with different data types. NumPy is a popular Python library for scientific computing that provides fast and efficient operations on multidimensional arrays. One of the features of NumPy is that it Continue reading
How to Use scipy.optimize.least_squares
In this blog post, I will show you how to use scipy.optimize.least_squares to solve nonlinear least squares problems in Python. Nonlinear least squares problems are optimization problems where the objective function is a sum of squared residuals, and the residuals depend on some nonlinear function of the parameters. For example, suppose we have some data Continue reading
Using scipy curve_fit to fit a function with multiple independent variables
In this blog post, I will show you how to use scipy curve_fit to fit a function with multiple independent variables. Curve fitting is a technique to find the best parameters for a model function that describes the relationship between a dependent variable and one or more independent variables. Scipy curve_fit is a function in Continue reading
How to resolve ValueError: operands could not be broadcast together with shapes
If you have ever worked with NumPy arrays, you might have encountered the ValueError: operands could not be broadcast together with shapes. This error occurs when you try to perform an operation on two arrays that have incompatible shapes. We will explain what broadcasting is, how NumPy determines the shapes of the operands, and how Continue reading
