# NOTE(zhiqiu): Since python 3.2, DeprecationWarning is ignored by default,
# and since python 3.7, it is once again shown by default when triggered directly by code in __main__.
# See details: https://docs.python.org/3/library/warnings.html#default-warning-filter
# The following line set DeprecationWarning to show once, which is expected to work in python 3.2 -> 3.6
# However, doing this could introduce one samll side effect, i.e., the DeprecationWarning which is not issued by @deprecated.
# The side effect is acceptable, and we will find better way to do this if we could.
