In my case  it was because the images I used were stored on a Mac  which generates many hidden files like  image file png  so they turned out to not even be the actual images I needed and I could safely ignore the warning or delete the hidden files  It was just an oversight in my case

If you are using Anaconda on windows then you can open Anaconda Navigator app and go to Environment section and search for pillow in installed libraries and mark it for upgrade to latest version by right clicking on the checkbox   Screenshot for reference   This has fixed the following error   PermissionError   WinError 5  Access is denied   e   work  anaconda  lib  site-packages  pil   imaging cp36-win amd64 pyd

first  check your pillow version  python -c  import PIL  print PIL PILLOW VERSION    I use pip install --upgrade pillow upgrade the version from 2 7 to 2 9 or 3 0  fixed this

For me it was fixed by downloading the image data set I was using again  in fact I forwarded the copy I had locally using vs-code s SFTP   Here is the jupyter notebook I used  in vscode  with it s output  from pathlib import Path  import PIL import PIL Image as PILI  from PIL import Image  print PIL   version     img path   Path  PATH UR DATASET miniImagenet train n03998194 n0399819400000585 jpg   print img path exists    img   PILI open img path  convert  RGB    print img   output  7 0 0 True  lt PIL Image Image image mode RGB size 158x160 at 0x7F4AD0A1E050 gt   note that open always opens in r mode and even has a check to throw an error if that mode is changed

For anyone who make it in bigger scale  you might have also check how many file descriptors you have  It will throw this error if you ran out at bad moment

Just a note for people having the same problem as me  I ve been using OpenCV cv2 to export numpy arrays into Tiffs but I had problems with opening these Tiffs with PIL Open Image and had the same error as in the title  The problem turned out to be that PIL Open Image could not open Tiffs which was created by exporting numpy float64 arrays  When I changed it to float32  PIL could open the Tiff again

So after struggling with this issue for quite some time  this is what could help you   from PIL import Image   instead of  import Image   Also  if your Image file is not loading and you re getting an error  No file or directory  then you should do this   path r C  ABC Users Pictures image jpg    and then open the file  image Image open path

For whoever reaches here with the error colab PIL UnidentifiedImageError  cannot identify image file in Google Colab  with a new PIL versions  and none of the previous solutions works for him     Simply restart the environment  your installed PIL version is probably outdated

In my case   I already had  quot from PIL import Image quot  in my code  The error occurred for me because the image file was still in use  locked  by a previous operation in my code   I had to add a small delay or attempt to open the file in append mode in a loop  until that did not fail   Once that did not fail  it meant the file was no longer in use and I could continue and let PIL open the file   Here are the functions I used to check if the file is in use and wait for it to be available  def is locked filepath       locked   None     file object   None     if os path exists filepath           try              buffer size   8               Opening file in append mode and read the first 8 characters              file object   open filepath   a   buffer size              if file object                  locked   False         except IOError as message              locked   True         finally              if file object                  file object close       return locked  def wait for file filepath       wait time   1     while is locked filepath           time sleep wait time

Seems like a Permissions Issue  I was facing the same error  But when I ran it from the root account  it worked  So either give the read permission to the file using chmod  in linux  or run your script after logging in as a root user

In my case the image file had just been written to and needed to be flushed before opening  like so   img file flush    img   Image open img file name
