Description

What steps will reproduce the problem?

I changed the interpreter to the path of a python exec in an env I had created
Clicked OK
Restart the kernels and that is when I got this error

Hey @jselwaness, thanks for reporting. You said:

I changed the interpreter to the path of a python exec in an env I had created

and I have a question for you about that: did you install Spyder-kernels in your environment?
