Question

I am installing pandas new version 1.0.3 using below command pip3 install pandas.

But I am getting below error

You are using pip version 8.1.1, however version 20.0.2 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.

I have tried installing pandas from below command

apt-get install python3-pandas

This commands work But it installs the old version of pandas.

I am using python 3.5 version and wanted to install latest version of pandas 1.0.3

Solution

Your error says you need to upgrade your pip:

pip install --upgrade pip

Or you could also try:

pip3 install --upgrade pip

Then pip3 -V should show you correct version it mentioned about.

Then try installing pandas using pip3 install pandas

On 19.10 it installs the latest version, but on 16.04 it installs older version. I think, it's because of newer versions of pandas do not support python 3.5:

Python version support
Officially Python 3.6.1 and above, 3.7, and 3.8

Did you ever hear of a thing called a Python virtual environment?

I have no problems with pip3 install pandas on 19.10, python 3.7, pip 18.1. So specify your specs: pip3 --version, cat /etc/lsb-release by editing your question.

I was also able to install it on 16.04, but it installs old version of pandas: 0.24.... Also, do what it asks: pip install --upgrade pip
