Jupyter笔记本不会将日志打印到输出单元格 [英] Jupyter notebook does not print logs to the output cell
问题描述
我目前正在使用 Jupyter 笔记本，我想强制它将 Python 日志打印到输出我正在使用过去以这种方式工作的旧笔记本，可能是旧版本的 Jupyter 笔记本。
我的日志记录设置为：
import logging
logging.basicConfig（format ='％（levelname）s：％（message）s'，level = logging.INFO）
logging.root.level = 20
但是当我打电话时：
logging.info （hello world）
它不会在输出单元格中打印任何内容。它只打印出控制台中的东西，我在其中启动了 Jupyter 笔记本。
我正在使用 python 2.7.10 我的虚拟环境中安装的软件包是：
appnope = = 0.1.0
backports-abc == 0.4
backports.ssl-match-hostname == 3.5.0.1
certifi == 2016.2.28

龙卷风== 4.3

是否更改了单元格中的打印输出？有什么方法可以强制 Jupyter 写出输出单元格的日志记录？
我找到了一个旧的 python 2.7.10 virtualenv其中 jupyter 按需运作。

有些套餐不相关使用 jupyter 问题，问题可能出现在某些相关软件包的版本中。我会尝试进一步调查确切的位置。
编辑：
在结束我发现问题出在包中： ipykernel == 4.3.1 或者自 ipykernel == 4.3.0 一切正常， ipykernel == 4.1.1 或 ipykernel == 4.2.2 。
github向jupyter和ipykernel报告了问题： https ：//github.com/ipython/ipykernel/issues/111
I am currently using Jupyter notebook and I would like to force it to print out Python logs to the output cell.
I am using old notebook that used to work this way, probably in older version of Jupyter notebook.
I have logging set as:
import logging
logging.basicConfig(format='%(levelname)s : %(message)s', level=logging.INFO)
logging.root.level = 20
But when I then call:
logging.info("hello world")
It does not print anything in the output cell. It just prints out the stuff in the console in which I started the Jupyter notebook.
I am using python 2.7.10 and installed packages in my virtual environment are:
appnope==0.1.0
backports-abc==0.4
backports.ssl-match-hostname==3.5.0.1
certifi==2016.2.28
decorator==4.0.9

six==1.10.0
terminado==0.6
tornado==4.3
traitlets==4.1.0
wheel==0.24.0
Was logging printout in the cell changed? Is there some way how I can force Jupyter to write out logging to the output cell?
I have found one my old python 2.7.10 virtualenv where jupyter works as desired.

Some packages are not related with the jupyter problem here, problem will probably be in versions of some relevant packages. I'll try further investigate exactly where.
EDIT:
At the end I have found that the problem is in the package: ipykernel==4.3.1 or since ipykernel==4.3.0 everything works fine with ipykernel==4.1.1 or ipykernel==4.2.2.
Issue was reported at github to the jupyter and ipykernel: https://github.com/ipython/ipykernel/issues/111
