If `k` is larger than `xs`, then the contents of `xs` itself will be returned. This differs from `random.sample` in that it returns a subsequence (i.e., order is preserved) and that it permits `k > len(xs)`. Args: rng: A `random` interface. xs: A sequence (`collections.abc.Sequence`). k: A non-negative integer. Returns: A new list whose elements are a subsequence of `xs` of length `min(k, len(xs))`, uniformly selected among such subsequences. csg|] }|qSrr)ri)xsrrr1sz_downsample..)lenlistsampler"movesxrangesort)r6rFkindicesr)rFrr4s  r4)rC __future__rrrr2r"ZwerkzeugrZ tensorboardrrZtensorboard.backendrZtensorboard.datar Ztensorboard.pluginsr Ztensorboard.plugins.histogramr rZTBPluginr r4rrrrs          o
