Read MoreActivation Functions in Pytorch
Pytorch is an open-source machine learning framework that is widely used to create machine learning models and provides various functions to create neural networks. The activation function is a key component of neural networks. The activation function determines the output of a node in the neural network given an input or set of inputs to the node. The activation function introduces non-linearity in the output of a node of the neural network which is necessary for solving complex machine-learning problems. What is an Activation Function ? Neural networks in artificial intelligence consist of an input layer, a hidden layer, and ...
Read MoreAction Chains in Selenium Python
Action chains in selenium python are the execution of multiple browser actions together in sequence. Selenium is a popular open-source automation testing tool used to test web applications and automate browser actions. Selenium can chain multiple browser actions together and this chaining of multiple actions is known as Action chains. In this article, we will discuss what action chains are in selenium python and how to use action chains to automate our web testing. What are Action Chains in Selenium Python? Action chains are a sequence of actions that are performed in a specific order on a web page to ...
Read MoreAccess meta data of various audio and video files using Python
We can access the metadata of audio files using Mutagen and the eyeD3 module in Python. For video metadata, we can use movies and the OpenCV library in Python. Metadata is the data that provides information about other data like audio and video data. Metadata of audio and video files include the format of the file, resolution of the file, file size, duration, bit rate, etc. By accessing these metadata we can manage the media more efficiently as well as analyze the metadata to get some useful information. In this article, we will look at some of the libraries or ...
Read MoreAccess files of a devices in the same network using Python
If multiple devices are connected over the same network i.e LAN or wifi then Python provides a way to access the files of the devices sharing the same network. Python built-in http.server module allows us to easily access the files of the devices connected over the same network. Http.server is a simple server that serves devices from the current directory or the chosen directory of the device when a request on the server is done. In this article, we will discuss the steps involved in accessing the files of a device in the same network using Python. Step 1 : ...
Read MoreAccess environment variable values in Python
Environment variables in Python are configuration values stored outside the code and are used at runtime by the application. These variables are present in the form of key-value pairs just like dictionaries in Python. These variables can be set, updated, or removed from the configuration file without changing the application code. Python gives many operating systems functions to access environment variables without affecting the code of the application. In this article, we will learn the ways in which we can access environment variables in Python. Using the OS Module In order to interact with the operating system python has an ...
