如何解决“ImportError:DLL load failed:”的fancyicomputer之前工作

Question

我以前可以成功地从一个Jupyterlab笔记本中导入fancyicompute模块，而不是其他笔记本。重新启动我的电脑后，所有笔记本电脑都会失败，并显示一个ImportError:DLL load failed:找不到指定的过程。“

为什么它在一个标签上有效，而在另一个标签上没有？ 而且，更令人担忧的是，为什么它会停止一起工作？在

其他一些关于类似错误的帖子指出，这可能与系统路径我调查过了。它工作的笔记本和不工作的笔记本之间的唯一区别是，它工作的那一个缺少factor iu analyzer-0.3.1-py3.6.egg的条目，这是我打开笔记本后添加的。在

我调查了搜索路径对于它工作的笔记本来说，它是这样的（我手动输入回车以使其更清晰）：

['C:\\Users\\laure\\Anaconda3\\envs\\scipy18jlab\\python36.zip', 
'C:\\Users\\laure\\Anaconda3\\envs\\scipy18jlab\\DLLs', 
'C:\\Users\\laure\\Anaconda3\\envs\\scipy18jlab\\lib', 
'C:\\Users\\laure\\Anaconda3\\envs\\scipy18jlab', 
'', 
'C:\\Users\\laure\\Anaconda3\\envs\\scipy18jlab\\lib\\site-packages', 
'C:\\Users\\laure\\Anaconda3\\envs\\scipy18jlab\\lib\\site-packages\\IPython\\extensions', 
'C:\\Users\\laure\\.ipython']

对于那些没有的人：

产生错误的代码是：

错误信息是：
