python - 使用 joblib 腌制文件时出现 TypeError

Question

我正在开发用于异常检测的扩展隔离林。alogirthm 的 Gihub 链接在此处。训练后我无法腌制模型。我该如何解决这个错误。

iso_forest_model = iso.iForest(X , ntrees=100, sample_size=256, ExtensionLevel=1)

import joblib

joblib.dump(iso_forest_model, os.path.join(models_path,'extended_isolation_forest.pkl'), compress=9)

错误
