Failed to change to virtual environment kernel with [Python conda envs: xxx] prefix

[Beliefuture]

When I want to change the kernel into a virtual environment through the panel and choose the prefix Python: [conda envs:xxx] one, it just can't work and print the following error message.

But when I choose the not Python: [conda envs:xxx] prefix that points out to the same environment which I rename, it can find the kernel. The two red blocks point to the same virtual environment py36.

I'm sorry we didn't get to this way back when. I'm closing this as stale but if you can offer a modern reproduction (new versions of conda, jupyter, nb_conda_kernels, etc.) please feel free to re-open or create a new issue
