-delete the python folder in the appdata folder -Create a new environment to run Spyder I have tried both of these and the problem has not been solved

Hi @yewen18,

I wanted to know how are you installing Spyder? Are you using the windows installers or are you trying with conda? Please let me know in the case you are using conda if you are using the defaults channel or the conda forge channel.

hi @steff456, I installed spyder via anaconda. After installing anaconda, spyder is already showing installed in the main page.

I have the same problem, I came form a problem with the "input" and install the version 3.10 something, and know i have this problem where the ipython console doesn't work, it says "conecting to kernel"

yewen18 commented 2 years ago

@steff456 Will this error still be resolved?

steff456 commented 2 years ago

@yewen18 ,the new environment where you are trying to install spyder-kernels uses Python 3.10? Also, why are you removing the python folder from the appdata folder?

Closing due to lack of response.
