我最近在新计算机上安装了Jupyter，在尝试使用virtualenv和不使用python -m notebook之后，我收到以下与线程模块相关的错误。此错误会阻止笔记本计算机（1）打开或（2）启动内核。

并尝试连接到内核后出现错误site-packages由于线程是内置模块，因此我无法对其进行更新。同样，使用常规virtualenv安装和干净的threading.py安装，此结果是相同的。
答案 0 :(得分：0)
我发现此错误是由于我的主目录的子目录中存在一个名为threading（与内置模块无关）的文件引起的。如果我从当前目录下目录树中文件所在位置的任何目录启动笔记本，则会收到此错误。
解决方案是在与内置import threading不存在命名冲突的目录中启动笔记本。
奇怪的是，如果我在发生故障的相同目录中的Python shell中dir(threading)，并运行n x n，它将获取正确的软件包。为什么Jupyter对此有不同的对待？
