即使文件存在，也加载 pickle 文件 returns 'could not find file with a name' (file_name)
Loading a pickle file returns 'could not find file with a name' (file_name) even when file exists
我正在尝试加载程序最近创建的用于保存玩家角色的 pickle 文件。昨天它还在工作，但是现在如果我输入现有文件的名称，它只是 returns: 'could not find file with a name' (file_name)。我不知道我是否不小心更改了某些内容，但最好将其排序。提前致谢。

我在加载 pickle 文件之前不小心删除了 save_game_load = save_game_name + '.pickle' : pickle_in = open(save_game_load,"rb").
