解决办法

试了好多方法，最终还是解决了，开心

1安装sqlite-devel

yum install sqlite-devel -y

重新编译python

tar -zxvf  Python-3.6.6.tgz
cd Python-3.6.6
./configure --prefix=/usr/local/python3.6.0
./configure --with-ssl 
make && make install

重启jupyter notebook

提示：
Running as root is not recommended. Use --allow-root to bypass
然后执行：

[......]$ jupyter notebook --generate-config --allow-root 
Overwrite /root/.jupyter/jupyter_notebook_config.py with default config? [y/N]y
Writing default config to:/root/.jupyter/jupyter_notebook_config.py

打开配置文件

gedit /root/.jupyter/jupyter_notebook_config.py

找到下面这一行
#c.NotebookApp.allow_root = False
去掉注释，将False改成True
c.NotebookApp.allow_root = True

保存后重新启动jupyter

参考：1、Python3报错ImportError: No module named pysqlite2
2、Running as root is not recommended. Use --allow-root to bypass
