I am trying to install "gmpy2" on Google Colab via the command:

!pip3 install gmpy2

I get the error:

Google Colab works on Description: Ubuntu 18.04.5 LTS Codename: bionic model name: AMD EPYC 7B12

pip3 --version
pip 21.1.3 from /usr/local/lib/python3.7/dist-packages/pip (python 3.7)

Why can't I install "gmpy2" ? What could be the reasons for this error?
