QUESTION
It appears that somehow one of my kernels is deleted. And perhaps that's why I am getting this error. How could I possibly fix it? Can I reinstall something (the kernel in the base environment perhaps)?
If no better option is available, I would try reinstalling anaconda altogether as a last resort according to: Default kernel in jupyter notebook (Python3) not working.
I have tried using the following:
- Installation of Jupyter Lab:
requirements already satisfied
- Kernels don't show up when runnning "jupyter lab"
- UI says "No kernel" while I definitively have one
- Getting Kernel Error while running Jupyter Notebook in Python3

ANSWER
Answered 2019-Oct-22 at 21:58Solution in DetailSolved the problem by editing the relevant
kernelspec
:kernel.json
file after fresh installation of Anaconda.
As reported earlier, I found that I had two kernelspecs
. (command: jupyter kernelspec list
)
- python3:
C:\Users\raysu\AppData\Roaming\jupyter\kernels\python3
- vpython:
C:\ProgramData\jupyter\kernels\vpython
The kernelspec
is a .json
file that maintains kernel-specifications for jupyter-notebook/lab to launch a certain kernel. Fortunately, the kernel vpython
was functioning and that helped me narrow down the source of the problem located inside kernelpsec: python3
. I had to correct the path to the python executable (python.exe
) and that solved the issue.
I would like to mention that in this case the following two resources came handy. I got more clarity in where the problem could be, after I saw the typical-structure of the kernelspec
document.
Note: However, since I cannot test this theory, I would ask anyone else in a similar problem, to first make a copy of the old kernel.json
file and then update the path to python.exe
file. If that resolves the kernel error, then reinstalling Anaconda altogether may not be necessary.
Long story short:
If your jupyter notebook/lab environment shows you kernel error, most likely the source of the problem is inside the kernelspec file: kernel.json
and the path to python.exe
is incorrect. This could be a more likely scenario, if the same kernel error
persists even after fresh re-installation of anaconda/jupyter-notebook/lab.
For instance, in my case, the python3-kernelspec
was located at:

Install pyforge
You can use pyforge like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
