Libraries to be installed

Here are the steps to install the Pillow library:

Make sure you have Python installed.
Open the command prompt (Windows) or terminal (Mac/Linux).
Enter the following command to install Pillow:

1
pip install Pillow

After the installation is successful, you can import the Pillow library for image processing:

1
from PIL import Image

If you encounter permission issues, you can use sudo or add administrator privileges to install:

1
sudo pip install Pillow

1
pip install Pillow --user

In Windows, you sometimes need to upgrade pip using the pip install -U Pillow command to install Pillow.
Pillow has some dependencies, so you may also need to install these during installation.

Example installation command:

Linux system/Mac: pip install Pillow
Windows: pip install Pillow or pip install Pillow --user

The main step is to use pip to install the Pillow library, and then you can import the PIL package in Python code and use Pillow.

Postscript
