cd mashumaro
python3 -m venv env && source env/bin/activate
pip install -e .
pip install -r requirements-dev.txt
./benchmark/run.sh

Error:

I guess you’re trying to run them on old Python version. Slots were added in Python 3.10.

Do you have a reason to run benchmarks on Python < 3.10 or we can close this issue?

Yeah, it was on python3.9 Thanks!
