In this article, we will discuss how to fix the No module named pandas error.

The error “No module named pandas ” will occur when there is no pandas library in your environment IE the pandas module is either not installed or there is an issue while downloading the module right.

Let’s see the error by creating an pandas dataframe.

Example: Produce the error

Python3




# import pandas
import pandas
  
# create dataframe
pandas.DataFrame({'a': [1, 2]})

Output:

We will discuss how to overcome this error. In python, we will use pip function to install any module

Syntax:

pip install module_name

So we have to specify pandas

Example: Installing Pandas 

Python3




pip install pandas

Output:

Successfully built pandas

Installing collected packages: py4j, pandas

Successfully installed py4j-0.10.9.2 pandas-3.2.0

We can verify by again typing same command then the output will be:

Output:

Requirement already satisfied: pandas in /usr/local/lib/python3.7/dist-packages (1.1.5)

To get the pandas description in our environment we can use the show command. This can help keep track of the module and its installation.

Example: Show module description 

Python3




# display pandas details
pip show pandas

Output:

Upgrade Pandas

Upgrading pandas is the best advantage to get error-free in your environment. So, we have to upgrade using the following command.

Example: Upgrading Pandas

Python3




pip3 install pandas - -upgrade

Output:

Install Specific version

To install a specific version of pandas we have to specify the version in the pip command.

Example: Installing a specific version of a module

Python3




# install 1.3.4 version
pip3 install pandas == 1.3.4

Output:

Find the version

If we want to find the version then we have to use __version__

Syntax:

module_name.__version__

Example: Get pandas version

Python3




#import module
import pandas as pd
  
# get the version
pd.__version__

Output:

1.1.5
