无法使用具有正确Python版本的Jupyter Notebook，并且Jupyter内核自动崩溃

Question

I am frustrated with this now.

I have been using Jupyter for a long time, everything went well. But recently I did some changes (I don't even remember, But I am sure I was forced to do that due to some occations, I am the worst, I know), and now the when I use Jupyter, the kernel shows "Python 3":

But Jupyter actually uses python2.7 (because of the crash I can't even provide a screenshot). Even worse, every time I open the notebook, it automatically crashes after 10 seconds.

I wanted to remove it and reinstall it, I am not sure which pip did I use to install it, but whenever I execute both pip2.7 uninstall jupyter or pip3.5 uninstall jupyter , I get the same result: " Cannot uninstall requirement jupyter, not installed ", so I can't even uninstall it.

And I am not using anaconda as well, I used to but later I found out jupyter couldn't import the packages install by anaconda at all so I uninstalled anaconda, so the jupyter I am using must be installed with pip .

Is there anyone who can help? I googled for a whole day trying to find solutions but couldn't. I am frustrated right now and really need to get back to my work.

Much appreciated.

thanks.

You could ignore whatever Python version are installed, redownload Miniconda , then configure PATH , and rely on it exclusively for most Python related things. Inside a anaconda/miniconda virtual environment, you could still use pip. You may try

conda create -p venv -y python=2 scipy 

source activate venv/

jupyter notebook
