import cProfile, os, tempfile
from IPython.display import Image
        
def cprof2png(command):
    # create tmp file to store cprof
    temp = tempfile.NamedTemporaryFile()
    # run profiler
    cProfile.run(command, temp.name)
    # parse to dot and make png figure from temp
    os.system(f"gprof2dot -f pstats {temp.name} | dot -Tpng -o {temp.name}")
    return Image(f"{temp.name}", format='png')
