To update Pandas to a specific or to a latest version you need to check next steps:

Steps to update Pandas

  • Activate the environment for Pandas
  • Check how Pandas was installed
    • Pip
    • Anaconda
    • Poetry
  • Check current Pandas version - optional
  • Upgrade Pandas to
    • specific version
    • latest version

Step 2. Check how Pandas was installed

To start you need to know how Pandas is installed and where. The simplest but not best way is to check which command is working for you:

To list packages in Pip virtual environment

pip list

or to check for Anaconda environment - get a list of all conda environments

conda info --envs

To check Poetry environment use:

poetry show --latest

There is a good extra reading on the topic here with best practices: Using Pip in a Conda Environment

Step 3. Check current Pandas version

To check which is the current Pandas version you can use:

3.1. Check Pandas version by PIP

!pip list | grep pandas

which will show something like:

pandas                            1.4.0

or the more detailed information by:

!pip show pandas
