It's failing the test for listing kernelspecs when one is invalid, and I don't think that can easily be fixed here; I'll need to change it in jupyter_client. |

Reopening to test with jupyter_client 5.2, which was just released. |

Looks like appveyor will fail until the jupyter_client conda package makes its way through the wickets. |

5.2, since it needed that to pass the tests? Or is the invalid-spec issue separate?

Yeah, it probably should be 5.2.

Using
find_kernel_specs()followed byget_kernel_spec()has quadratic performance with the number of available kernels, because it effectively rescans for each available kernel. Hands up, I designed this, and I can't think why I did it this way.I thought this was going to require some ugly workaround, but thankfully @captainsafia was on the case two years ago, adding the
get_all_specs()method (jupyter/jupyter_client#93). So all I've done here is switch the notebook code to use it.This should improve performance loading pages for anyone with several kernels installed.
Closes gh-3135
