In BiocSklearn: interface to python sklearn via Rstudio reticulate

#' mediate access to python modules from sklearn.decomposition
#' @import reticulate
#' @import knitr
#' @import Rcpp
#' @note Deprecated.  Previously returned a list with elements np (numpy), pd (pandas), h5py (h5py),
#' skd (sklearn.decomposition), joblib (sklearn.externals.joblib), each
#' referring to python modules.  This was done directly with reticulate, but basilisk package
#' discipline is more reliable.
#' @examples
#' \dontrun{
#' els = SklearnEls()
#' names(els$skd) # slow at first
#' # try py_help(els$skd$PCA) # etc.
#' }
#' @return list of (S3) "python.builtin.module"
