Are you tired of encountering the frustrating “Could not import PIL.Image” error while working with TensorFlow or Keras’ `load_img` function? You’re not alone! This error has plagued many a developer, but fear not, dear reader, for we’re about to dive into a step-by-step guide to resolving this issue once and for all.
What’s causing the error?
The `load_img` function in TensorFlow and Keras relies on the Python Imaging Library (PIL) to handle image processing tasks. When you encounter the “Could not import PIL.Image” error, it usually indicates that PIL is either not installed or not properly configured on your system.
PIL Installation: A Refresher
Before we dive into the fixes, let’s quickly review how to install PIL. You can use pip, the Python package installer, to install PIL:
pip install pillowNote that the package name is `pillow`, not `PIL`. Yes, it’s a bit confusing, but `pillow` is the friendly PIL fork that’s actively maintained.
Fixing the Error: Step-by-Step Instructions
Now that we’ve covered the basics, let’s get to the meat of the matter. Follow these steps to resolve the “Could not import PIL.Image” error:
-
Check PIL Installation
Verify that PIL is installed correctly by running the following command in your terminal or command prompt:
pip show pillowIf PIL is not installed, you’ll see a message indicating that the package is not found. Install PIL using the command above, and then try running your code again.
-
Update PIL
If PIL is already installed, try updating it to the latest version:
pip install --upgrade pillowThis might resolve any compatibility issues or bugs that could be causing the error.
-
Check Python Version
Ensure that you’re using a compatible Python version with PIL. You can check your Python version using:
python --versionPIL supports Python 3.6, 3.7, 3.8, and 3.9. If you’re using an older version, consider upgrading to a supported version.
-
Versions Conflicts: A Possibility?
In some cases, version conflicts between PIL and other packages might cause the error. Try uninstalling PIL and then reinstalling it:
pip uninstall pillow pip install pillowThis will ensure that PIL is installed correctly and without any version conflicts.
-
Virtual Environment: A Fresh Start
If none of the above steps work, try creating a new virtual environment and installing PIL again:
python -m venv myenv source myenv/bin/activate pip install pillowThis will give you a fresh start and help you isolate any environment-related issues.
-
Reinstalling TensorFlow or Keras
If the issue persists, try reinstalling TensorFlow or Keras:
pip uninstall tensorflow keras pip install tensorflow kerasThis might resolve any package-related issues that are causing the error.
Additional Troubleshooting Tips
Still stuck? Don’t worry, we’ve got some additional tips to help you troubleshoot the issue:
-
Check for any permissions issues. Make sure that your Python script has the necessary permissions to access the images.
-
Verify that the image file path is correct and the image file is not corrupted.
-
Try loading the image using other libraries like OpenCV or matplotlib to see if the issue is specific to PIL.
Conclusion
That’s it! With these steps and troubleshooting tips, you should be able to resolve the “Could not import PIL.Image” error and get back to working with TensorFlow or Keras’ `load_img` function. Remember to stay patient and methodical in your approach, and don’t hesitate to seek help if you’re still stuck.

Here are 5 Questions and Answers about “TensorFlow/Keras `load_img` Error: "Could not import PIL.Image"”:
Frequently Asked Question
Having trouble with TensorFlow/Keras’ `load_img` function? Don’t worry, we’ve got you covered!
Q1: What is the “Could not import PIL.Image” error, and why does it occur?
This error occurs when the Python Imaging Library (PIL) is not installed or not properly configured. PIL is a required dependency for TensorFlow/Keras’ `load_img` function, which is used to load and preprocess images.
Q2: How do I install PIL to fix the “Could not import PIL.Image” error?
You can install PIL using pip: `pip install pillow` (not `pip install pil`, as `pil` is an older version). If you’re using a virtual environment, make sure to activate it before installing.
Q3: What if I’m using a Jupyter Notebook or a Python script, and I’ve already installed PIL, but the error persists?
Try restarting your Jupyter Notebook kernel or Python script. Sometimes, the kernel/script needs to be restarted to recognize the newly installed package. If you’re still facing issues, try reinstalling PIL or checking your Python version (PIL supports Python 3.7-3.10).
Q4: Can I use other image processing libraries instead of PIL?
While PIL is the default and recommended library, you can use other libraries like OpenCV or matplotlib. However, you’ll need to modify the `load_img` function to work with these libraries, which might require additional code and configuration.
Q5: How can I troubleshoot further if none of the above solutions work?
Check your Python and PIL versions, ensure you’ve installed PIL correctly, and verify that your environment is properly configured. If you’re still stuck, try searching for similar issues on GitHub, Stack Overflow, or the TensorFlow/Keras documentation for more specific guidance.
