Machine Learning

In Python, when we develop big projects it is difficult to write all the code in single file. The code is divided into sub files which help to modular the code. It make our debugging and understand of project structure better. One common scenario that developers encounter is, how to import Python files from the […]

What is the “Python Got Multiple Values for Argument” Error mean? In simple terms, the “multiple values for argument” error occurs when we pass more than one value for arguments of the function or method and Python doesn’t know which one to use. When we define a function or method we specify the arguments or

What is regularization ? Regularization is a technique in machine learning for preventing overfitting and improving model generalization. Some examples of regularization techniques are L1 Regularization (Lasso), L2 Regularization (Ridge), Elastic Net, Dropout, Early Stopping etc . Note: The coefficients represent the estimated weights for each feature in the model in context of Lasso and

What is the Bottom Layer of a Decision Tree? Decision trees are supervised algorithms used for developing classification and regression models in machine learning. The bottom layer also known as the leaf layer is where final predictions are made. After splitting the data multiple times throughout the tree, the final output is derived in the

What is the “Failed Building Wheel” Error? When we try to install a Python package some time we see error “Failed Building Wheel”. This error indicates that the installation process couldn’t compile a wheel file for that package. In this error “Error failed building wheel for numpy” it failed to compile for Numpy Package. What

In pandas we have a .to_csv() method which gives a way to export a dataframe to a csv file. Syntax : df.to_csv(path_or_buf, sep=’,’, na_rep=”, float_format=None, columns=None, index=True, index_label=None, mode=’w’, encoding=None, compression=None, quoting=None, quotechar='”‘, line_terminator=’n’, chunksize=None, date_format=None, doublequote=True, escapechar=None, decimal=’,’, thousands=None, dtype=None) We have a long list of parameters in the to_csv() function but we will

Errors are part of coding. Having a good understanding of error handling makes you a better developer. In this blog we will learn Python error handling best practices. Why Error Handling is Important?Error handling helps the application to gracefully tackle the error and prevents the application from crashing. It provides information about the error. Overview

What is a ‘dict_keys’ Object in Python? Dict_keys objects are a special type of dynamic view which shows keys in a dictionary. Which means that any changes made in the dictionary will be reflected in the dict_keys view. In simple terms ‘dict_keys’ object is a view object which provides a dynamic view of keys in

What does unhashable type mean in Python? Unhashable type means that object does not have a fixed hash value. Object like that cannot be used  as a key in a dictionary or an element in a set. Data structures like dictionaries and sets are hash based data structures. Hash based data structures means that the structure relies
