is not going to be frozen to produce an executable. '''中文翻译''' 尝试在当前进程完成引导阶段之前启动新进程。 这可能意味着您没有使用fork来启动子进程,而且您在主模块中忘记使用正确的惯用法: if __name__ == '__main__': freeze_support() ... 如果程序不打算被冻结以生成可执行文件,则可以省...
I have already tried changing the banner timeout from 15 seconds to 60 secs in the transport.py, but it did not solve the problem. 我看到有个timeout和transport.py,就想到现网那些报Error reading SSH protocol banner错误的机器也是非常卡,而且目测了下发起paramiko连接到报错的时间,基本是相同的。 于...
如果向不存在的主机发出请求,并且一旦产生了超时,我们会得到一个ConnectionError异常: >>>r = requests.get('http://url_not_exists') requests.exceptions.ConnectionError: HTTPConnectionPool(... 在这个屏幕截图中,我们可以看到在 Python 空闲中执行之前的命令: 与urllib 相比,请求库使得在 Python 中使用 HTTP ...

This lock is necessary mainly because CPython’s memory management is not thread-safe. (However, since the GIL exists, other features have grown to depend on the guarantees that it enforces.) 上面的核心意思就是,无论你启多少个线程,你有多少个cpu, Python在执行的时候会淡定的在同一时刻只允许一...
It's also possible to only log failures that are going to be retried. Normally retries happen after a wait interval, so the keyword argument is calledbefore_sleep: .. testcode:: import logging import sys logging.basicConfig(stream=sys.stderr, level=logging.DEBUG) logger = logging.getLogger(...
