第一次见到它，我特别害怕，

很大一个文件，还是二进制的，是什么意思呢？该文件是深度学习模型训练完成之后由模型的输出数据保存的结果数据；

在线JSON编译器

JSON Editor Online
把文件传上去！
发现是一个大大的dictinary，

回忆起，在代码里保存的时候，使用的是长这样的语句：

final_logs = logger.get_logs()
print('\nSaving session data to {}/logs.json'.format(P['save_path']))
with open(os.path.join(P['save_path'], 'logs.json'), 'w') as f:
    json.dump(final_logs, f)

其中logger类如下所示（其他函数未展示）

class train_logger:
    
    '''
    An instance of this class keeps track of various metrics throughout
    the training process.
    '''
    
    def __init__(self, params):
        
        self.params = params
        
        # epoch-level objects:
        self.best_stop_metric = -np.Inf
        self.best_epoch = -1
        self.running_loss = 0.0
        self.num_examples = 0
        
        # batch-level objects:
        self.temp_preds = []
        self.temp_true = [] # true labels
        self.temp_obs = [] # observed labels
        self.temp_indices = [] # indices for each example
        self.temp_batch_loss = []
        self.temp_batch_reg = []
        
        # output objects: 
        self.logs = {}
        self.logs['metrics'] = {}
        self.logs['best_preds'] = {}
        self.logs['gt'] ={}
        self.logs['obs'] = {}
        self.logs['targ'] = {}
        self.logs['idx'] = {}
        for field in self.logs:
            for phase in ['train', 'val', 'test']:
                self.logs[field][phase] = {}
