This is going to install pylibafl python module into this venv.

First, make sure the python virtual environment is activated. If not, run source .env/bin/activate . Running pip freeze at this point should display the following (versions may differ):

maturin==0.12.6
pylibafl==0.7.0
toml==0.10.2

Then simply run

python PATH_TO_BABY_FUZZER/baby_fuzzer.py

The crashes directory will be created in the directory from which you ran the command.
