python - KernelRestarter：在 jupyter 中重新启动失败，内核死亡

问题描述

[I 10:43:53.627 NotebookApp] 启动notebooks 在本地路径: /opt/soft/recommender/jupyter

[I 10:43:53.627 NotebookApp] 本程序运行在: http://10.48.204.120:8888/

[I 10:46:11.948 NotebookApp] Saving file at /notebooks/elasticsearch-spark-recommender.ipynb

我正在尝试使用命令通过 pyspark 启动 jupyter notebook：

PYSPARK_DRIVER_PYTHON="jupyter" PYSPARK_DRIVER_PYTHON_OPTS="notebook"
../spark-2.2.0-bin-hadoop2.7/bin/pyspark --driver-memory 4g --driver-class-path /opt/soft/recommender/spark/elasticsearch-hadoop-5.3.0/dist/elasticsearch-spark-20_2.11-5.3.0.jar

我可以通过远程浏览器打开jupyter，但是由于内核重启失败，我无法通过jupyter运行python demo。

python版本是3.5.0。Jupyter 和 ipykernel 都是最新的。prompt-toolkit版本是 1.0.15。

如果我prompt-toolkit将版本更新到 2.0.4，那么启动 pyspark 会抛出很多错误消息。

我该如何解决？

解决方案

这篇文章在我的情况下解决了。 Jupyter-notebook 报错 KernelRestarter: restart failed 或者“内核启动，请稍候”

基本上，卸载文章中列出的所有软件包并重新安装 jupyter 和 notebook

pip uninstall -y ipykernel ipython jupyter_client jupyter_core traitlets ipython_genutils jupyter notebook tornado
pip install jupyter notebook
