Your code is running with Pandas version X, now you want to upgrade to version X+1. How do you know your code is still giving the same results?

There are other implementations of Pandas: cuDF, Dask, Koalas, Modin. Can you switch to another implementation and still get the same results?

Setup:

python3 -m venv venv
. venv/bin/activate
pip install modin[ray] pandas

Running:

BEARCAT_PANDAS=pandas python example.py
BEARCAT_PANDAS=modin.pandas python example.py
python bearcat-diff.py bearcat-output-modin.pandas.pkl bearcat-output-pandas.pkl
