Look Siluet Width like a possible metric to evaluate 'clusters'

An example of how to run a sweep for the UMAP DR notebook is now in _papermill_caller.ipynb. It can be seen that, all you need is a call to pm.execute_notebook as function of the sweep agent. That will execute the whole notebook.

In the notebook itself, the only thing that you have to care about is that, when a config parameter could be set from outside the notebook, check that before assigning it as part of the wandb.config object. For example, before the code was:

config_dr.min_dist = 0.1

and now it is:

config_dr.min_dist = ifnone(config_dr.get('min_dist'), 0.1)

When calling the notebook from a sweep, the sweep will magically prepare the config_dr with everything that you are sweeping over (e.g., min_dist), so it will already have that value assigned. In case the notebook is called normally, that field will be empty and you just assign a default value as usual (in this case 0.1).

The method ifnone is an utility from fastcore
