When I open the spyder in anaconda, the spyder indicates that an error ocurred while starting the kernel in spyder

Question

When I open the Spyder in anaconda, the Spyder indicates that an error occurred while starting the kernel in Spyder. I have tried (in the terminal) two suggested commands from Spyder. However, after I restart anaconda and open Spyder, the same problem exists, so I don't know how to solve the problem. Thank you for your help!

Below is what Spyder says when opened:

An error occurred while starting the kernel

Your Python environment or installation doesn't have the spyder‑kernels module or the right version of it installed. Without this module is not possible for Spyder to create a console for you.

You can install it by running in a system terminal:

conda install spyder‑kernels=0.*

or

pip install spyder‑kernels==0.*

The results in the terminal are listed below.

Answer 1

Also, installing matplotlib solved the issue for me.

Answer 2

Check for a compatible version of spyder-kernel from here and install using pip like this-

pip install spyder-kernels== COMPATIBLE VERSION

Answer 3

If the solution by @lyq didn't work, this worked for me.

Open Anaconda prompt and run this line:

spyder --reset

Answer 4

you can try:

conda install spyder-kernels

or

pip install spyder-kernels
