Note that please first set up your SageMath environment and then run our python file.

How to set up SageMath environment?

First step: conda setup

1. install miniconda: https://docs.conda.io/en/latest/miniconda.html bash Miniconda3-latest-Linux-x86_64.sh Note: if you have error "UnicodeDecodeError: ‘ascii‘ codec can‘t decode byte", just type command: export LC_ALL=C.UTF-8 source ~/.bashrc delete previous environment:
   conda env remove -n name

Second Step: sagemath install

1. set conda-forge:
   conda config --add channels conda-forge
2. change to restrict mode:
   conda config --set channel_priority strict
3. create a conda environment named sage:
   conda create -n sage sage python=3.9
4. note: you can change the environment name as you like
   conda create -n {name} sage python=3.9
