just used memray to find out where my python program was allocating memory and was super impressed by how easy it was to use https://github.com/bloomberg/memray

the steps were just:

1. `memray run python3 my_program.py`
2. copy and paste the snippet it prints out ("memray flamegraph memray-manage.py.37954.bin") to generate a flamegraph
3. open the html flamegraph in my browser
