ROR: Could not find a version that satisfies the requirement d2l (from versions: none) ERROR: No matching distribution found for d2l

It seems that you are trying to install the package called d2l with Ruby on Rails (ROR), but it's encountering an error. However, d2l is not a Ruby gem and is not specifically designed for ROR.

The package d2l is typically associated with the Deep Learning book, which provides code examples and utilities for deep learning tasks. To use d2l, you should install it using Python and not ROR.

Here are the steps to install d2l in Python:

1. Make sure you have Python and pip installed on your system.
2. Open a terminal or command prompt.
3. Run the following command to install d2l:

pip install d2l

Make sure you have an active internet connection and that you have the necessary permissions to install packages. After the installation is complete, you should be able to import and use the d2l library in your Python code.
