PyTorch DataLoader is a Python module that provides a set of tools for efficiently loading and transforming data for use in a PyTorch neural network. It helps define how data is loaded, transformed, and fed into a model. It also provides an efficient way to batch, shuffle, and iterate over datasets. DataLoader makes it easier to load and process data, allowing developers to focus more on building and training models.



The PyTorch DataLoader class is used to load data from a dataset and feed it to a model for training or evaluation. The DataLoader class provides a convenient way to iterate over a dataset, with the ability to batch, shuffle, and load the data in parallel.


Here is an example of loading data using PyTorch DataLoader.

Code


In this solution, we use the DataLoader of the PyTorch.

Instructions

Follow the steps carefully to get the output easily.

  1. Install Jupyter Notebook on your computer.
  2. Open terminal and install the required libraries with following commands.
  3. Install PyTorch - pip install torch.
  4. Copy the code using the "Copy" button above, and paste it into your IDE's Python file.
  5. Add print statements for the variables my_dataset and my_dataloader using the following commands.
  6. print (my_dataset) and print(my_dataloader)
  7. Run the file to load data using PyTorch DataLoader


I hope you found this useful. I have added the link to dependent libraries, version information in the following sections.


I found this code snippet by searching for "Loading data using PyTorch DataLoader" in kandi. You can try any such use case!

                      Environment Tested


                      I tested this solution in the following versions. Be mindful of changes when working with other versions.

                      1. The solution is created in Python 3.9.6
                      2. The solution is tested on PyTorch 2.0.0+cpu version.


                      Using this solution, we are able to perform indexing and slicing of tensor in PyTorch in Python with simple steps. PyTorch is also used in Computer Vision and Generative Adversarial Networks.
