Python、Django、pickle资源Errno2无此类文件或目录：

我目前正试图在运行虚拟机的ubunutu上安装一个诗歌生成器。当我运行服务器，输入文本并点击generate时，我得到以下错误：

Exception Type:     IOError
Exception Value:    

[Errno 2] No such file or directory: 'poetry_generator/resources/bigram.pickle'

Exception Location:     /home/lee/Downloads/PoEmo-master/poetry_generator/architecture/experts/generating_experts/collocation_expert.py in train, line 31

poetry_生成器中没有/resources文件夹，其中也没有bigram.pickles文件。它将以下脚本的链接31标识为问题：

有什么想法吗？我是python新手，所以我对python不是很了解。谢谢

错误发生在

train

方法的第三行，但您捕获了该行。然而，在捕捉中，你尝试了完全相同的事情。更改打开文件的方式不会忽略此错误。如果文件/目录不存在，则需要先创建它

有关递归创建目录的信息，请参见

对于创建文件，可能会有所帮助。
