IPython.parallel - 我可以将自己的日志写入引擎日志吗？ [英] IPython.parallel - can I write my own log into the engine logs?

问题描述

我希望能够在相关的引擎日志中记录我传递给引擎的函数的输出。

I'd like to be able to log outputs from the functions I pass to my engines in the relevant engine logs.

即：

data = /* my list of data to operate on */
def fn(inval):
    import logging
    log = logging.getLogger()
    log.error('This is on the engine')
    // do stuff
    return result

calculated_data = []
for datum in data:
    calc = view.apply(fn, datum)
    calculated_data.append(calc)

我希望能够在相关的引擎日志中看到针对特定任务运行的日志语句。

I'd like to be able to see the log statements in the relevant engine log that operated on the specific task.

推荐答案

您可以使用以下方式获取当前应用程序的记录器（即本例中的引擎）：

You can grab the logger of the current app (i.e. the engine in this case) with:

from IPython.config import Application
log = Application.instance().log

然后正常登录，它将转到引擎日志。

Then log as normal, and it will go to the engine logs.
