Like I said, it’s the same problem as the other threads; you don’t have your dependencies installed in repl.it and you just need to use the packager tool and poetry to install them.
This time you need matplotlib, pandas, and scipy. Uninstall everything, reinstall, and watch the console errors. numpy will tell you that you need a newer python than 3.7 and once you fix that in pyproject.toml, scipy will tell you that it needs python = ">=3.8,<3.12". Once you update pyproject.toml accordingly, scipy installs and the project runs.
