我正在尝试通过 pyspark 启动 jupyter 笔记本，使用命令：

\n\n

PYSPARK_DRIVER_PYTHON="jupyter" PYSPARK_DRIVER_PYTHON_OPTS="notebook"\n../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\n

\n\n

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。

\n\n

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

\n\n

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

\n\n

我该如何修复它？

这篇文章解决了我的情况。 Jupyter-notebook报错KernelRestarter: restart failed或者“kernel running,please wait”

基本上，卸载文章中列出的所有软件包并重新安装 jupyter 和笔记本

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