如何显示Jupyter笔记本的版本并在Jupyter笔记本中运行单元格？我收到一个错误：错误的翻译

标签： python kernel anaconda jupyter-notebook

我已经安装了Anaconda，我使用conda环境和conda命令来安装软件。

当我输入： jupyter notebook --version

我收到以下错误：

zsh: /Users/cr517/.local/bin/jupyter: bad interpreter: /Users/cr517/anaconda/envs/snakes/bin/python: no such file or directory 5.2.1

我可以输入：jupyter notebook xyz.ipynb打开一个jupyter笔记本，但我无法运行任何单元格。运行后，单元格标有*。很快，此消息显示在弹出框中：

The kernel has died, and the automatic restart has failed. It is possible the kernel cannot be restarted. If you are not able to restart the kernel, you will still be able to save the notebook, but running code will no longer work until the notebook is reopened.

打开一个jupyter notebok后，我在终端上得到了这个：

确实没有/Users/cr517/anaconda/envs/snakes/bin/python但为什么Jupyter Notebook会尝试使用它？我在这里有一个运行良好的Python：

jupyter notebook在网络浏览器中打开我的目录，但不会创建新笔记本。

我在终端输入python --version并获得：

Python 3.6.3 :: Anaconda custom (x86_64)

*如何查看iPython版

您可以使用public void InitializeComponent() { ... this.ValueChanged += MCCustomDateTimePicker_ValueChanged; } protected void MCCustomDateTimePicker_ValueChanged(object sender, EventArgs e) { txtOnDTP.Text = this.Value.ToString(); }

进行检查

conda list ipython

答案 1 :(得分：9)

您可以尝试以下方法：

jupyter --version

答案 2 :(得分：1)

  • 这绝对是一个路径问题：你在/Users/cr517/anaconda/bin/python
    • 中有你的anacondda python解释器路径
  • 但你的jupyter指向/Users/cr517/.local/bin/jupyter，但它应该指向/Users/cr517/anaconda/bin/jupyter
  • 运行以下命令gedit /Users/cr517/anaconda/bin/jupyter
  • 检查打开文件的第一行，该文件将具有jupyter的硬编码路径，并检查文件中的路径是否正确
  • 如果路径不是/Users/cr517/anaconda/bin/jupyter而不是/Users/cr517/anaconda/bin/jupyter
  • 但是这里的问题可能无法解决，因为如果你做ls *jupyter*其他jupyter文件很多这些文件都有硬编码的路径可能是错的，这可能是你能够打开他的ipynb而不能创建单元格
  • 这是太多的工作要做...手动更改每个文件的路径
  • 只需重新安装anaconda即可解决问题
  • 如果您要重新安装，请运行此bash Anaconda....sh -b -p "Users/cr517/anaconda"
