我正在尝试理解和调试应用程序中的内存泄漏。
我使用tracemalloc模块间隔3小时拍摄了2个快照，其中我的应用程序的内存增加了25mb。这是comparison = snapshot2.compare_to(snapshot1, 'filename', cumulative=True)

我正在努力从这些数据中得出任何有用的结论。
traceback.py在这里增长近1mb的情况是什么？有8522个项目，平均大小为111个字节。有谁知道会发生什么？
更奇怪的是，从traceback.py引用了/usr/lib/python3.6/traceback.py，而从我的virtualenv /home/ubuntu/foobar/lib/引用了许多其他内容。
我会在这里提供Python专家的任何指导。
