What is the method for installing offline libraries in Python?

There are usually several methods for installing offline libraries in Python.

1. Download offline installation package: First, download the required library’s offline installation package (usually a .whl file) on a computer that can connect to the internet, then copy the file to the target machine. Install using the pip command, the command format is as follows:

pip install package_name.whl

1. Utilize offline installation tools such as pip-offline or pip-download to download offline installation packages and install them without an internet connection.
2. Create a virtual environment on a networked machine, install the necessary libraries within that environment, and then copy the entire virtual environment folder to the target machine.

Ensure that the libraries installed offline are compatible with your Python version and that no errors occur during the installation process, regardless of the method used.
