Matplotlib Error: ‘LinearSegmentedColormap’ object has no attribute ‘resampled’

What You Will Learn

In this detailed guide, you will master the resolution of the Matplotlib error message that mentions a ‘LinearSegmentedColormap’ object lacking the attribute ‘resampled’. Explore how to effectively handle colormaps in Matplotlib and troubleshoot such errors with ease.

Introduction to the Problem and Solution

Encountering the error “‘LinearSegmentedColormap’ object has no attribute ‘resampled'” often signals an issue concerning how Matplotlib manages colormaps. This error arises when attempting to access a non-existent method or property on a colormap object.

To overcome this challenge, it is crucial to understand the correct attributes and methods associated with Matplotlib colormaps. By delving into the workings of colormaps in Matplotlib, you can adeptly address and resolve this error scenario.

Code

# Import necessary libraries
import matplotlib.pyplot as plt

# Create a sample plot with a colormap
plt.imshow([[1, 2], [3, 4]], cmap='viridis')
plt.colorbar()

# Display the plot
plt.show()
