Attributeerror: nonetype object has no attribute shape

In this article, we will show you how to solve the error attributeerror: 'nonetype' object has no attribute 'shape'. What does this error indicate and why does it occur? If you have that thought in your mind, read through to the end of this article to find the answer.

The error attributeerror: nonetype object has no attribute shape is an error in Python that occurs when you attempt to access the shape() attribute of an object that has a “None” value.

It just means that this error indicates that you attempted to carry out an action that needs the input data to have a specified shape, but that operation failed because the data had a value of None and hence lacked a shape attribute.

Before we begin our tutorial, have a quick overview of Python and AttributeError.

What is Python?

Python is one of the most popular programming languages. It is used for developing a wide range of applications. It is a high-level programming language that is usually used by developers nowadays due to its flexibility.

What is AttributeError?

An attributeerror is an error that appears in our Python codes when we try to access an attribute of a non-existent object. In addition, this occurs when we attempt to perform non-supported operations.

Now that we understand this error and even what Python and an AttributeError are, let’s move on to our “how to fix this error” tutorial.

How to solve “nonetype object has no attribute shape” in Python

Time needed: 2 minutes

The following is a step-by-step guide to resolve the Python error attributeerror: nonetype object has no attribute shape.

  1. Check the input data.


    The first step is to use the if statement to check if the input data isn’t “None” before accessing the attributes.

  2. Put the variable on an appropriate object.


    The next step is to put the variable on an appropriate object before accessing its attributes if the variable is None.

  3. Use the try-except block.


    To get and handle the attributeerror, you can use the try-except block, where you can print an error message.

Example:

import numpy as np

sample_data = None

if sample_data is not None:
    shape = sample_data.shape
    print("Shape of data:", shape)
else:
    print("Sample input data is None.")

if sample_data is None:
    sample_data = np.zeros((7, 13))
try:
    shape = sample_data.shape
    print("Shape of data:", shape)
except AttributeError:
    print("Sample input data has no shape attribute.")

Output:

Sample input data is None.
Shape of data: (7, 13)

Conclusion

In conclusion, the Python error attributeerror: 'nonetype' object has no attribute 'shape' can be easily solved by making sure that the input data isn’t None before accessing the attributes.

By following the guide above, there’s no doubt that you’ll be able to resolve this error quickly and without a hassle.
