Spyder debugger not working [poll]

Question

It may happen that while running the spyder debugger it gives a strange error: 

runfile() got an unexpected keyword argument 'current_namespace'

I checked on the internet and I managed to solve the problem by downgrading some anaconda packages:

if you have the same problem open the terminal and paste these two commands, it worked fine for me:

conda activate my_env
conda install ipykernel=6.2.0

### no choices found for poll!

Answer 1

thanks, this helped me.

Answer 2

After the commands, you might need to close and re-open Spyder as had the issue also. Good day :))
