tiner
Block-wise, thread-safety timer for loops
Install
pip install tinerUsage
Works like a context manager
from tiner import tiner
from time import sleep
with tiner("see this block"):
sleep(1)
# return the block running time
print(tiner.get('see this block'))or as a python decorator
@tiner('see this function')
def f():
#do somethingGlobal mining and grouping
the timing is managed by tiner, not its instances:
# A.py
for _ in range(20):
with tiner("t1"):
#do something
...
# B.py
for _ in range(20):
with tiner("t2"):
#do something
...
# main.py
tiner.table()

for _ in range(10):
with tiner("test:loop"):
sleep(duration)
tiner.table(verbose=True)

from tiner import tiner
from time import sleep
for _ in range(10):
#do something
with tiner("see this loop"):
sleep(0.1)
#do something
# return the block running time over the loops
print(tiner.get('see this loop'))Handle asynchronous programs
import os
from tiner import tiner
# tiner will call the synchronize function when the block is over
with tiner("loop", synchronize=torch.cuda.synchronize):
# machine learning running
# return the block running time over the loops
print(tiner.get('loop'))Easy to use
A timer should be clear and simple
tiner.get(BLOCK_NAME) # return a certain block running time so far
tiner.table([BLOCK1, ...]) # print some blocks' time on a formatted table
tiner.zero([BLOCK1, ...]) # empty some blocks' time
tiner.disable() # disable time logging
tiner.enable() # enable time loggingNOTE:
tiner's timing is relatively precise. You should only use it for comparison of the timings of different blocks in one run, not for different runs of your program.
