如何获得 Python Pillow (PIL) 版本？

Question

I would like to get the PIL (Python Imaging Library) version installed on a Mac OS X computer. I've previously installed Pillow , a more friendly fork of PIL.

I've tried:

import PIL
print('PIL',PIL.__version__)

And I've got the error:

AttributeError: module 'PIL' has no attribute '__version__'

Answer 1

Use PIL.__version__ .

Before Pillow version 6.0.0, its version string could be accessed via the following variable names:

>>> PIL.version.__version__
'5.1.0'
>>> PIL.PILLOW_VERSION
'5.1.0'
>>> PIL.__version__
'5.1.0'
>>>

Not to be confused with the last PIL version that Pillow is built on (and thus hangs on to):

>>> PIL.VERSION
'1.1.7'

There was no information on this in the documentation regarding the fork from PIL: https://pillow.readthedocs.io/en/5.1.x/about.html#why-a-fork

However, PIL's homepage states

Status
The current free version is PIL 1.1.7. This release supports Python 1.5.2 >and newer, including 2.5 and 2.6. A version for 3.X will be released later.

That release is dated "November 15, 2009".

This confirms it's just PIL's last release version.

For future/further digging:

The version string is defined in these source files: https://github.com/python-pillow/Pillow/blob/master/src/PIL/version.py and https://github.com/python-pillow/Pillow/blob/master/src/PIL/__init__.py , or search for all occurences of __version__ in the repository.

(On my Windows, this is installed to %LocalAppData%\\Programs\\Python\\Python36\\Lib\\site-packages\\PIL\\version.py )

Update

https://pillow.readthedocs.io/en/stable/releasenotes/5.2.0.html

5.2.0 API Changes Deprecations

These version constants have been deprecated. VERSION will be removed in Pillow 6.0.0, and PILLOW_VERSION will be removed after that.

 `PIL.VERSION` (old PIL version 1.1.7) `PIL.PILLOW_VERSION` `PIL.Image.VERSION` `PIL.Image.PILLOW_VERSION`

Use PIL.__version__ instead.

https://pillow.readthedocs.io/en/stable/releasenotes/6.0.0.html

6.0.0 Backwards Incompatible Changes

Removed deprecated VERSION

VERSION (the old PIL version, always 1.1.7) has been removed. Use __version__ instead.

Answer 2

To get the version for PIL do

>>> PIL.VERSION
'1.1.7'

Edit:

This gives you only the PIL version not the Pillow version. See this answer for more detail.

Answer 3

I tried the above answers, nothing worked for me, but this did (for version 8.0.1:

from PIL import Image
dir(Image)
# AH HAH!  there is an attribute __version__
print(Image.__version__)

8.0.1

Answer 4

Finally I've found a solution:

from PIL import Image 
print('PIL',Image.VERSION)

Answer 5

If you are not importing the entire PIL library but instead have something like this:

from PIL import Image, ImageTk, ImageDraw, ImageFont

Then this works:

print('Image.VERSION', Image.VERSION)
print('Image.PILLOW_VERSION', Image.PILLOW_VERSION)

Results:

Image.VERSION 1.1.7
Image.PILLOW_VERSION 3.1.2

Note: Ubuntu 16.04.6 LTS uses older version of Pillow that was tested back in 2016. It appears the Ubuntu Folks (Canonical) don't like to upgrade python versions after testing.
