如标题所示,我在 conda 系统中遇到了 jupyter 的问题。
版本:
- Ubuntu 16.04 LTS
- 康达 4.3.30
- jupyter 4.4.0(我已经卸载然后在出现上述错误后再次安装)
我所做的是遵循(简而言之)
source activate my_env1
pip install jupyter_contrib_nbextensions
# (I'm aware that I should have used conda install...)
jupyter contrib nbextension install --user
jupyter nbextension enable codefolding/main
jupyter contrib nbextensions migrate
pip install RISE
jupyter-nbextension install rise --py --sys-prefix
jupyter-nbextension enable rise --py --sys-prefix
请注意,在上述之前没有问题发生。
1. jupyter notebook 报错
然后jupyter notebook
在“my_env1”中运行并打开笔记本后,无法连接内核并显示以下消息:
ERROR:tornado.general:Uncaught exception in ZMQStream callback
Traceback (most recent call last):

handler = _signal.signal(_enum_to_int(signalnum), _enum_to_int(handler))
ValueError: signal only works in main thread
2.其他conda环境下jupyter命令出错
在另一个名为“my_env2”的环境中,任何类似的命令都会jupyter XXX
停止并显示以下错误消息:
Traceback (most recent call last):
File "***my_env2***/bin/jupyter-notebook", line 4, in <module>
import notebook.notebookapp
File "***my_env2***/lib/python3.6/site-packages/notebook/__init__.py", line 25, in <module>
from .nbextensions import install_nbextension
File "***my_env2***/lib/python3.6/site-packages/notebook/nbextensions.py", line 31, in <module>
from .config_manager import BaseJSONConfigManager
ModuleNotFoundError: No module named 'notebook.config_manager'
中的描述~/.jupyter/jupyter_notebook_config.json
:
{
"NotebookApp": {
"nbserver_extensions": {
"nbpresent": true,
"jupyter_nbextensions_configurator": true
}
}
}
我做了什么来解决它
然而,以下试验并未解决。
- 通过 conda 重新安装 jupyter
- 禁用 nbextension 但由于上述错误而无法正常工作
- 移走 ~/.jupyter/ 中的配置文件(检查后撤消没有帮助)
- 从源https://github.com/jupyter/notebook设置 jupyter notebook但
pip install .
返回消息Failed to run bower: [Errno 2] No such file or directory: 'bower': 'bower'
(我想知道为什么它需要bower
而不是尝试)
问题
我的问题很简单:
- 我该如何解决?
如果缺少信息,请通知我。谢谢你。
评论
我之前在由同一个anaconda3创建的另一个环境(比如my_env3)中使用过nbextension,当时没有问题。
