^ what my notebook interface looks like

What the kernel error reads:

How did you install this? anaconda2 indicates that Python 2 is installed and anaconda3 indicates that Python 3 is installed as well. Since both of them show up together here, maybe something is mixed up? If you don’t need Python 2 and the corresponding Anaconda version, I suggest you to remove it.
