过去几个月来我一直在使用jupyter笔记本。我是第一次遇到这类问题。
确切的问题：当我在jupyter笔记本上运行单元时，它运行了很长时间，但是没有显示任何输出。
我已经根据一些Google搜索尝试过的解决方案： 1.卸载anaconda并重新安装。 2.更新的conda 3.更新了ipykernel 4.下载并安装Microsoft Visual C ++ 2015重新分发更新3 5.重新启动内核，然后重试 6.在运行选项卡中关闭文件 7.依此类推。
属性： 1. Windows 10专业版 2. Python：Python 3.6.7 3. Jupyter：- jupyter核心：4.6.3 jupyter笔记本：6.1.1 qtconsole：4.7.5 ipython的：7.16.1 ipykernel：5.3.4 jupyter客户：6.1.6 jupyter实验室：未安装 nbconvert：5.6.1 ipywidgets：7.5.1 nbformat：5.0.7 特质：4.3.3 4. Anaconda 3-64位
在jupyter笔记本提示中显示错误：
