analysis3-18.10 kernel missing in jupyter

[aidanheerdegen]

If the analysis3-18.10 environment is loaded the corresponding python kernel is not available in jupyter. If a different environment is loaded, the 18.10 kernel is available in the jupyter drop down menu.

This might be due to an upgrade to 2.2.0 of nb_conda_kernels

anaconda/nb_conda_kernels#113

Pinning nb_conda_kernels to 2.1.0 fixed this issue

[mcg1969]

The kernel is almost certainly there—it's the one designated Python 3 (or Python 2, if you're running Python 2).
