Python 为什么我在Jupyter笔记本中出现内核错误？

我是python的新手。在打开jupyter笔记本时，我在内核中遇到以下错误。有什么办法可以解决吗？jupyter的安装已经通过Anaconda3完成——尝试过重新安装和设置环境变量，但到目前为止运气不佳。任何帮助都将不胜感激

如果您的电脑上安装了Python，请从cmd或powershell运行：

pip install jupyterlab

然后，您可以从以下内容开始：

jupyter lab

看起来您在jupyter对Windows的依赖性出现问题时安装了它。看见我也犯了同样的错误

---

现在应该在conda上修复它，因此如果您从conda卸载并重新安装jupyterlab，它将不再抛出该错误。

安装可能错过了一些步骤，这些步骤是通过后期安装修复的。 转到YoutVenv的脚本目录并运行命令

python .\pywin32_postinstall.py -install

确保您正在运行具有管理员权限的shell。

• 步骤2命令：

  conda activate（环境文件夹的位置）

• 步骤3命令：

  python-mipykernel安装--user

适用于Windows。
