profiling module¶

Utilities for profiling time and memory.

timeit function¶

timeit(
    func,
    readable=True,
    **kwargs
)

Run timeit() on a function.

MemTracer class¶

MemTracer()

Context manager to trace peak and final memory usage using tracemalloc.

Usage

>>> from vectorbtpro import *

>>> with vbt.MemTracer() as tracer:
>>>     np.random.uniform(size=1000000)

>>> tracer.peak_usage()
'8.0 MB'

>>> tracer.peak_usage(readable=False)
8005360

final_usage method¶

MemTracer.final_usage(
    readable=True,
    **kwargs
)

Get final memory usage.

**kwargs are passed to humanize.naturalsize.

peak_usage method¶

MemTracer.peak_usage(
    readable=True,
    **kwargs
)

Get peak memory usage.

**kwargs are passed to humanize.naturalsize.

Timer class¶

Timer()

Context manager to measure execution time using timeit().

Usage

>>> from vectorbtpro import *

>>> with vbt.Timer() as timer:
>>>     sleep(1)

>>> timer.elapsed()
'1.01 seconds'

>>> timer.elapsed(readable=False)
datetime.timedelta(seconds=1, microseconds=5110)

elapsed method¶

Timer.elapsed(
    readable=True,
    **kwargs
)

Get elapsed time.

**kwargs are passed to humanize.precisedelta.

end_time property¶

End time.

start_time property¶

Start time.
