# Often, i'll be working in on a jupyter notebook and an error/bug will
# interrupt the execution of something that was wrapped with the tqdm
# function. This has the annoying side effect where your next tqdm call
# will be multilined. To fix this, you can the below two lines of code
# and it'll be fixed! (if tqdm gets interrupted again, you'll have the 
# run these two lines again).
while len(tqdm._instances) > 0:
    tqdm._instances.pop().close()
