WebApr 13, 2024 · Scikit-Learn is a popular Python library for machine learning that provides simple and efficient tools for data mining and data analysis. The cross_validate function is part of the model_selection module and allows you to perform k-fold cross-validation with ease. Let’s start by importing the necessary libraries and loading a sample dataset: WebThe Sampler performs a rounding operation based on the allow_duplicates parameter to decide the local sample count. Public Functions DistributedSampler( size_t size, size_t num_replicas = 1, size_t rank = 0, bool allow_duplicates = true) void set_epoch( size_t epoch) Set the epoch for the current enumeration. how to cure uterine cancer
