Example 1: Importing Scikit-learn and Loading a Dataset Scikit-learnprovides several built-in datasets for learning purposes. One popular dataset is the “Iris” dataset, which contains data about different species of iris flowers. To load theIrisdataset, use the following code: from sklearn.data...
Our example will be based on the famous Iris dataset (Fisher, R.A. “The use of multiple measurements in taxonomic problems” Annual Eugenics, 7, Part II, 179–188 (1936)). I downloaded it usingsklearnpackage, which is aBSD(Berkley Source Distribution) license software. I modified the fe...

要从训练运行中保存模型,请使用正在使用的框架的log_model()API。 例如,mlflow.sklearn.log_model()。 有关详细信息,请参阅记录 MLflow 模型。 若要将现有模型迁移到 MLflow,请参阅将自定义模型转换为 MLflow。 提示 记录大型模型时,可能会遇到错误“Failed to flush the queue within 300 seconds”。 通常,这...
