I am totally new to Jupyter Notebook.

Currently, I am using the notebook with R and it is working well.

Now, I tried to use it with Python and I receive the following error.

[I 09:00:52.947 NotebookApp] KernelRestarter: restarting kernel (4/5), new random ports

Hopefully, someone can help me.

I had the same problem, I fixed in the way its say in Github: https://github.com/jupyter/notebook/issues/4079

  • open Anaconda Prompt typing

    python -m ipykernel install --user

It's more stable to create a kernel with an Anaconda virtualenv.

Follow these steps.

  1. Execute Anaconda prompt.
  2. Type conda create --name $ENVIRONMENT_NAME R -y
  3. Type conda activate $ENVIRONMENT_NAME
  4. Type python -m ipykernel install
  5. Type ipython kernel install --user --name $ENVIRONMENT_NAME

Then, you'll have a new jupyter kernel named 'R' with R installed.

ipython` 7.0.1 has requirement prompt-toolkit<2.1.0,>=2.0.0, but you'll have prompt-toolkit 1.0.15 which is incompatible

https://github.com/jupyter/jupyter_console/issues/158

Upgrading prompt-toolkit will fix the problem.

pip install --upgrade prompt-toolkit

First Select your environment name. In my case it was "env".

Then install the jupyter notebook from there. It worked for me.

Check your environment variable Path! In the system variable Path add the following line

C:\Users\\AppData\Roaming\Python\Python37\Scripts
