To update the Python version in Google Colab, you can leverage the Debian-based Linux environment provided by Colab. Similar to upgrading Python on your own Linux system, you can follow these steps:
- Detect the current Python version in Colab:
!python --version # Output: Python 3.8.16
2. Install the desired Python version, such as Python 3.9:
!sudo apt-get update -y !sudo apt-get install python3.9
3. Configure the alternatives to switch between Python versions:
!sudo update-alternatives --install /usr/bin/python3 python3 /usr/bin/python3.8 1 !sudo update-alternatives --install /usr/bin/python3 python3 /usr/bin/python3.9 2
4. Verify the Python version after the update:
!python --version # Output: 3.9.16
5. To ensure the Colab kernel uses the new installed Python version, execute the following commands:
!sudo apt-get install python3.9-distutils !wget https://bootstrap.pypa.io/get-pip.py !python get-pip.py !python -m pip install ipython ipython_genutils ipykernel jupyter_console prompt_toolkit httplib2 astor !ln -s /usr/local/lib/python3.8/dist-packages/google /usr/local/lib/python3.9/dist-packages/google
6.Remember to restart the Colab runtime after making these changes. Additionally, note that you’ll need to reinstall any packages (e.g., pandas, TensorFlow) in the new Python version.
If you want to view a list of installed Python versions and switch between them, use the command:
!sudo update-alternatives --config python3 # After running, enter the row number of the Python version you want.
By following these steps, you can update the Python version in Google Colab to 3.9 or above, allowing you to work with the desired Python environment.”
