According to Installation instructions, the most likely cause of this error is that pip version in your environment is outdated. Please upgrade to pip 20.3+ in order to install a pre-built manylinux wheel, or from the source distribution.
Pip can be upgraded in Google Colab environment by running
!pip install pip --upgrade
