In this Python tutorial, we will discuss the value error “matplotlib unknown projection ‘3d’ in python”. Here we’ll cover the reason and solution related to this error using matplotlib. And we’ll also cover the following topics:
- Oldest Version Issue
- Installation Issue
- Syntax Error
Matplotlib unknown projection ‘3d’
Here in this section, we will discuss various reasons and their solution for the error “Matplotlib unknown projection ‘3d’“
Error#1: Oldest Version
Firstly understand that mplot3D works differently in different versions of matplotlib. Here we discuss the ValueError: matplotlib unknown projection ‘3d‘ in matplotlib version 0.99.
So firstly you have to confirm that which version are you using?
Syntax to check the version:
# Import library import matplotlib # Check Version print matplotlib."__version__"
If you’re using matplotlib 0.99, in which case you’ll need to use slightly different syntax or upgrade to a more recent version.
Let’s see the solution for this:
The first and easiest way, to resolve this attribute error is to upgrade matplotlib to a recent version.
The below command is used to upgrade matplotlib to the latest version in Jupyter Notebook.
pip install --upgrade matplotlib
If you have Anaconda Prompt in your system, you can easily update matplotlib to the latest version, from here using the below-mentioned commands.
conda update matplotlib #OR conda update -all
Here the first command only updates the matplotlib package and the second updates all the packages.
The second way to resolve this error is to use a slightly different syntax instead of using the projection keyword argument.
Use the following syntax:
# Import Library from mpl_toolkits.mplot3d import axes3d, Axes3D # Set Projection Axes3D()
Error #2 Installation Issue
The first, reason is that maybe matplotlib is not installed.
- To install matplotlib use the pip command.
pip install matplotlib
- To install matplotlib use the conda command.
conda install matplotlib
The second, reason is that may be matplotlib is not properly installed. So, firstly, uninstall the matplotlib package and again install it. Above we discuss the installation of matplotlib. Here we discuss the uninstallation of matplotlib.
- To uninstall matplotlib use the pip command.
pip uninstall matplotlib
- To uninstall matplotlib use the conda command.
conda uninstall matplotlib
Error#3 Syntax Error
If you are not using matplotlib’s oldest version and the matplotlib package is properly installed, but still, you get an error then maybe you have a syntax error.
Below is the proper syntax:
# Import Library from mpl_toolkits import mplot3d # Projection ax = plt.axes(projection="3d")
