snapshot

spp-net中保存最好测试结果的训练模型

spp-net-master/finetuning/spp_finetune_voc.m中

if (mean(test_error) < min_test_error)             min_test_error = mean(test_error);             finetuned_model_path = fullfile(opts.finetune_rst_dir, sprintf('FT_iter_%d', iter_));             caffe('snapshot', finetuned_model_path);             fprintf('best! save as %s\n', finetuned_model_path);

solver.cpp中snapshot的实现部分     // Save a snapshot if needed.     if ((param_.snapshot()          && iter_ % param_.snapshot() == 0          && Caffe::root_solver()) ||          (request == SolverAction::SNAPSHOT)) {       Snapshot();     }
