训练模型运行出错

您好，我想请教您两个问题：
1. 依赖库##Dependencies必须要下载吗？我运行train_model.m文件时会跳到globalregression.m函数中的model = train(deltashapes(:, o), sparse(binaryfeatures), param)这一行，出现错误“未定义与 'double' 类型的输入参数相对应的函数 'train'。”
其中，我已经将 parpool(4)命令注释掉了
2.该检测算法适合手掌关键点检测吗？

Start with train_model.m and trace the call into globalregression.m, especially model = train(deltashapes(:, o), sparse(binaryfeatures), param). Inspect the Dependencies section and verify which MATLAB package provides train. Done means reproducing or resolving the reported error and documenting whether the detection algorithm supports palm keypoints.
