问题
While importing, Python(anaconda) gives the following error:
ImportError: cannot import name 'PILLOW_VERSION' from 'PIL'
I tried removing pillow and then conda install but the error persists. Please help
回答1:
Pillow 7.0.0 removed PILLOW_VERSION, you should use __version__ in your own code instead.

Edit (2020-01-16):
If using torchvision, this has been fixed in v0.5.0. To fix:
- Require
torchvision>=0.5.0 - If Pillow was temporarily pinned, remove the pin
Old info (2020-01-09):
If using torchvision, there is a release planned this week (week 2, 2020) to fix it:
- https://github.com/pytorch/vision/issues/1712#issuecomment-570286349
The options are:
- wait for the new torchvision release
- use the master version of torchvision (eg.
pip install -U git+https://github.com/pytorch/vision) - install torchvision from a nightly, which also requires a pytorch from a nightly version
- or install Pillow<7 (eg.
pip install "pillow<7")

I have solved by modifying functional.py and __init__.py which are mentioned in error message.Error.
Modify from PIL import Image, ImageOps, ImageEnhance, PILLOW_VERSION to from PIL import Image, ImageOps, ImageEnhance, __version__ in functional.py approx line number 5.
Modify PILLOW_VERSION = __version__ = _version.__version__ to __version__ = __version__ = _version.__version__ in __init__.py, approx line no 22.
File path:
functional.py:C:\Users\UserName\AppData\Local\Programs\Python\Python37\Lib\site-packages\torchvision\transforms\functional.py__init__.py:C:\Users\UserName\AppData\Local\Programs\Python\Python37\Lib\site-packages\PIL\__init__.py

Downgrade pillow if you don't need latest features
pip install pillow==6.1
回答4:
- Currently using torchvision==0.4.2 and this solved my problem.
Downgrade your pillow to 6.1 and restart your Jupyter notebook.
Use this
conda install pillow=6.1
