Jupyter笔记本电脑的CPU使用率低

我注意到某些单元需要很长时间才能在Jupyter笔记本上执行.在任务管理器中查看时，我发现python进程仅使用了大约4％的CPU.我正在使用Python 3.6.2

I have noticed that some cells take a long time to finish executing on my Jupyter Notebooks. When looking in the task manager, I see that the python process is only using up to about 4% of the CPU. I am using Python 3.6.2

我在Windows上，但是正在使用"Windows上的Ubuntu上的Bash"终端启动Jupyter笔记本(也许有帮助).该处理器是Core i7，该进程没有用完所有可用的RAM，因此这不是交换内存问题.

I am on Windows but am using the "Bash on Ubuntu on Windows" terminal to launch the Jupyter notebook (maybe this helps). The processor is a Core i7 and the process is not using up all available RAM so it isn't a Swap memory problem.

基本上，为什么它会像这样被限制"，我该如何解决?

Basically, why is it being "throttled" like this and how can I fix it?
