The java.io.IOException is a checked exception in Java that indicates a problem while performing Input/Output (I/O) operations. This usually happens when a failure occurs while performing read, write or search operations in files or directories. Since IOException is a checked exception, it must be explicitly handled in methods that can throw this exception - either by using a try-catch block or by throwing it using the throws clause.

Using the localStorage web storage API, web applications can store key-value pairs locally in a web browser, allowing you to persistently retain data on the client-side even if the user shuts their browser or navigates away from the website.

This happens when a PyTorch embedding tensor attempts to access an index that is out of bounds. A lookup table that converts integers into vectors of real numbers is known as an embedding tensor.
