Fix No module name matplotlib error


First check the version of Python installed on your server.

[root@centos /]# python3 -V
Python 3.6.8

The below command checks whether python-pip is installed or not :

[root@centos /]# rpm -qa | grep -i pip


[root@centos /]# pip3 -V
pip 21.3.1

Run the command ‘yum install python-pip’ OR ‘yum install python3-pip’ to install python-pip package on your CentOS server.

pip is the package installer for Python. To install matplotlib using pip:

# pip3 install matplotlib

Import matplotlib to make sure it is installed correctly.

[root@centos /]# python3
Python 3.6.8 (default, Nov 21 2019, 19:31:34)
[GCC 8.3.1 20190507 (Red Hat 8.3.1-4)] on linux
Type “help”, “copyright”, “credits” or “license” for more information.
>>> import matplotlib

OR you can run ‘pip3 freeze | grep -i matplotlib’ to confirm

[root@centos /]# pip3 freeze | grep -i matplot

Follow the below steps if you want to install a specific version of matplotlib

Example :

#pip3 install matplotlib==3.3.3

The above command will install matplotlib version 3.3.3.
