Notes ----- The frequency semantics of :term:`sample_weight` is guaranteed when `max_samples` is a float or integer, but not when `max_samples` is None. The returned `n_samples_bootstrap` will be the same between a weighted dataset with integer `sample_weights` and a dataset with as many rows repeated when `max_samples` is a float or integer. They will differ when `max_samples` is None (the weighted and repeated datasets do not have the same number of rows). Parameters ---------- n_samples : int Number of samples in the dataset. max_samples : None, int or float The maximum number of samples to draw. - If None, then draw `n_samples` samples. - If int, then draw `max_samples` samples. - If float, then draw `max_samples * n_samples` unweighted samples or `max_samples * sample_weight.sum()` weighted samples. sample_weight : array of shape (n_samples,) or None Sample weights. Returns ------- n_samples_bootstrap : int The total number of samples to draw for the bootstrap sample. Nzthe number of samples is  z#the total sum of sample weights is  gUUUUUU?z'Using the fractional value max_samples=z when zresults in a low number (zQ) of bootstrap samples.
