import copy copy.copy() copy.deepcopy() copy() is a shallow copy function. If the given argument is a compound data structure, for instance a list, then Python will create another object of the same type (in this case, a new list) but for everything inside the old list, only thei...
When using the data collector SyncDataCollector from torchrl, the deepcopy fails (see error below). This seems to be due to the pruned connections, which sets the pruned layers with gradfn (and not requires_grad=True) as suggested in this post. Here is an example of code I would lik...
In the sections below, you will learn about deep copy and ways to achieve it in JavaScript.Use the structuredClone() Method to Create a Deep Copy of an Object in JavaScriptOne of the ways of creating a deep copy of an object in JavaScript is using the structuredClone() method. The ...
Welcome to the sixth installment of the How to Python series. Today, we’re going to learn how to clone or copy a list in Python. Unlike most articles in this series, there are actually quite a few options—some better than others. In short, there are so many different ways to copy...
In Python, there are several modes for file handling (file open modes) including: Read mode ('r'): This mode is used to read an existing file. Write mode ('w'): This mode is used to write to a file. It will create a new file if the file does not exist, and overwrite the fil...
While loops can also be used to implement generators in Python. A generator is a function that uses a yield statement and generates values on command. Below we’ll create our own implementation of the range() function. We’ll use the yield statement in a while loop to generate continuous ...
Stochastic gradient descent is a technique in which, at every iteration, the model makes a prediction based on a randomly selected piece of training data, calculates the error, and updates the parameters. Now it’s time to create the train() method of your NeuralNetwork class. You’ll save...

For Python 2, you’ll need to install virtualenv by running pip install virtualenv, while Python 3 now includes the same functionality out-of-the-box. To create a virtual environment in a new directory, all you need to do is run one command, though it will vary slightly based on your ...
