If you’re a Python developer, you may have encountered the error message “cannot import name pillow_version from pil” when trying to run your code. This error message is related to the Python Imaging Library (PIL), which is a library used for opening, manipulating, and saving different image file formats. In this article, we’ll explore the causes of this error and provide steps to fix it.
One possible cause of this error is a version mismatch between the PIL and Pillow packages. Another cause could be an issue with the installation of these packages. We’ll dive deeper into these causes and provide step-by-step instructions on how to fix this error.
Understanding Pillow and PIL
Pillow and PIL are two Python libraries used for image processing. PIL stands for Python Imaging Library, which was created in the early days of Python, while Pillow is a fork of PIL that was developed to add support for Python 3 and to continue development after the original PIL was discontinued in 2011.
The main difference between the two libraries is that PIL only supports Python 2, while Pillow supports both Python 2 and Python 3. This makes Pillow a more up-to-date and versatile library for image processing in Python.
The development of Pillow was led by Alex Clark, who was also one of the developers of the original PIL library. Pillow is now the recommended Python Imaging Library by the Python Software Foundation and is widely used in the Python community.
