我刚刚安装了孔雀鱼0.1.10。然后输入Ipython 2.1.0
from guppy import hpy
hp = hpy()
使控制台崩溃,即Windows告诉我,python.exe刚刚崩溃。有没有解决方法?还是一个很好的替代方案?
答案 0 :(得分:3)
我和guppy / heapy有同样的问题。 Guppy目前有点过时了。有一些补丁但我再也找不到它了。然而它在python 2.7中对我没有用。由于操作系统拱门(64位!?),您也可能遇到问题。
关于内存分析技术还有其他问题:
我个人认为最有价值的替代方案是:
计算对象的大小并自行跟踪它也很有用。我详细阐述了一些代码(最初由https://stackoverflow.com/users/216356/noctis-skytower),我在其中一个StackOverflow问题(Approximately how much memory would a list of 80000 items consume in python?)中找到了与Python 2.7兼容的代码(也应该在3中工作):
totalSizeOf = lambda obj: sum(map(sys.getsizeof, explore(obj, set())))
def explore(obj, memo):
loc = id(obj)
if loc not in memo:
memo.add(loc)
yield obj
# Handle instances with slots.
try:
slots = obj.__slots__
except AttributeError:
pass
else:
for name in slots:
try:
attr = getattr(obj, name)
except AttributeError:
pass
else:
#yield from explore(attr, memo)
for bar in explore(attr, memo):
yield bar
# Handle instances with dict.
try:
attrs = obj.__dict__
except AttributeError:
pass
else:
#yield from explore(attrs, memo)
for bar in explore(attrs, memo):
yield bar
# Handle dicts or iterables.
for name in 'keys', 'values', '__iter__':
try:
attr = getattr(obj, name)
except AttributeError:
pass
else:
for item in attr():
#yield from explore(item, memo)
for bar in explore(item, memo):
yield bar
