🐛 Bug

__init__ on SparseAdam iterates over params to check if sparse Tensors are included, but it does not take a possibility that the params is actually a generator for example in a case where we use model.parameters. Therefore it fails the initialization with ValueError: optimizer got an empty parameter list in such cases.

To Reproduce

Steps to reproduce the behavior:

Describe the workflow you want to enable

A parameter accepting custom bin edges as an array.

Describe your proposed solution

Use pd.cut() under the hood or any other computa

Recent discussions on Discourse suggest that not all users know about apropos (or equivalently, using ?"..." for text search). The startup message currently mentions

Type "?" for help, "]?" for Pkg help.

I suggest that text search is added to this, but I am still looking for a compact way of phrasing it.

Currently, the C++ compiler generates lots of warnings: https://xgboost-ci.net/blue/organizations/jenkins/xgboost/detail/master/516/pipeline/61. It would be great to reduce the number of warnings.
