Nameerror: name image is not defined [SOLVED]

Are you stuck with the Python nameerror: name image is not defined error message?

Well, you’re lucky enough because this article will show you how to fix this error.

Apart from that, you’ll also understand what nameerror name image is not defined means and why it occurs.

What is “nameerror name image is not defined”?

The nameerror: name image is not defined, occurs when you’re trying to use a variable or function named image, but that variable or function has not been defined or declared.

It is a common Python error that occurs when you try to reference a variable or object that hasn’t been defined.

In simple words, Python doesn’t know what the “image” variable is supposed to be because you haven’t told it yet.

Here’s an example scenario that results in this error:

For instance, in Python code that uses the Keras library for machine learning, this error can occur if the image module from keras.preprocessing is not imported correctly.

from keras.preprocessing.image import ImageDataGenerator

As you can see, you only import the ImageDataGenerator from the image. However, you also need other attributes.

To fix this error, import the image module explicitly by adding the line from keras.preprocessing import image to your code.

✅ from keras.preprocessing import image

Why does this error occur?

The nameerror: name ‘image’ is not defined can be raised because of some reasons, such as:

❌ If there is a typo in the variable name.

❌ If the variable is being used before it has been assigned a value.

❌ If the code is missing an import statement for a module that defines the image variable or function.

How to fix “nameerror: name image is not defined”?

To fix the nameerror name image is not defined, check your code to ensure that the image variable or function is properly defined and assigned a value before it is used.

Import Image class from the PIL (Python Imaging Library) module.

For example:

✅ from PIL import Image

try:
    image = Image.open('sample.png')
    image.show()
except FileNotFoundError:
    print("Error: File not found.")

After running this code it will show an image that you’re to use, with out any error.

We also use a try block to attempt to open the file sample.png using the Image.open() method, and then displaying the image using the show() method.

If the error still exists, try to execute the following steps:

✅ Check if the variable or function image has been misspelled. If it has been misspelled, correct the spelling.

✅ Check if the necessary module has been imported. If the image variable or function is part of a module that has not been imported, you will need to import the module before using it.

✅ Check if the variable or function image has been defined in your code. If it has not been defined, you will need to define it before using it.

✅ Check your Imports, if you’re working with a module or package that defines the “image” variable, ensure that you’ve imported it first.

Conclusion

In conclusion, the nameerror: name image is not defined, occurs when you’re trying to use a variable or function named image, but that variable or function has not been defined or declared.
