The AttributeError: `module 'PIL.Image' has no attribute 'ANTIALIAS'` suggests that you're trying to access an attribute named `ANTIALIAS` in the `PIL.Image` module that doesn't exist or is no longer available under that name. The Python Imaging Library (PIL) has been succeeded by the Pillow library, which is a fork of PIL and is more actively maintained. It's important to ensure that you're using a recent version of Pillow, as some constants have been moved to different locations or renamed over time for clarity and consistency. As of Pillow version 6.0.0 (released on April 1, 2019), the `ANTIALIAS` constant has been renamed to `Image.Resampling.LANCZOS`. This change was made to better reflect the resampling filter being used, as `ANTIALIAS` was effectively an alias for `LANCZOS`. Here is an example of using the `LANCZOS` filter instead of `ANTIALIAS`: ```python from PIL import Image, ImageResampling image = Image.open("path_to_your_image.jpg") # This is the updated way to use the resampling filter resized_image = image.resize((new_width, new_height), ImageResampling.LANCZOS) ``` If you're working with older versions of PIL or Pillow, `Image.ANTIALIAS` would still be the correct constant to use. However, it's advisable to use the latest versions of Pillow whenever possible to benefit from the various improvements and to keep your codebase up-to-date. Here's what you should do: 1. Update Pillow to the latest version using pip: ``` pip install --upgrade Pillow ``` Make sure to do this within your virtual environment if you're using one. 2. Replace any occurrences of `Image.ANTIALIAS` with `Image.Resampling.LANCZOS` or simply `Image.LANCZOS` to match the updated library behavior and nomenclature. This should solve the raised `AttributeError` and make your code compatible with current and future versions of Pillow.
