jupyter-notebook - 为 PyTorch 启动 Jupyter 内核时如何解决连接问题？

Question

我按照此链接中的步骤从 Conda (Anaconda) 安装 PyTorch： https ://timoast.github.io/blog/installing-pytorch/

然后我按照以下链接中的步骤添加了 virtualenv (cnn) 的内核： https ://medium.com/@jeremy.from.earth/multiple-python-kernels-for-jupyter-lab-with-conda -c67e50de3aa3

当我启动 Jupyter 并为 PyTorch 内核选择环境时，我收到连接失败错误并显示以下错误消息。知道如何克服此错误以从 Jupyter 成功连接到内核吗？.
