系统找不到指定的路径
请问这是什么原因报错？数据集文件已经和工程文件放在同一个目录下了你把directory = "_path_to_dataset_"
改成directory = "./你的数据集文件"
可以把数据集文件的文件名截图或发给我吗 数据集文件是个压缩包，我已经解压并重命名为dataset但是还是报错 ckblt 发表于 2022-2-3 19:46
你把directory = "_path_to_dataset_"

数据集文件是个压缩包，我已经解压并重命名为dataset但是还是报错 你是解压到dataset文件夹里了，对吧？
那你应该改为directory ="./dataset" _path_to_dataset_翻译成中文是 “dataset的路径” 名字只有七个字 发表于 2022-2-3 20:26

改了之后又有新的错误{:5_104:}还是找不到系统路径 报错截图，和代码所在文件夹截图 名字只有七个字 发表于 2022-2-3 20:34
报错截图，和代码所在文件夹截图
这个.mf文件是压缩包里面的文件 你能把全部代码发过来吗？ 名字只有七个字 发表于 2022-2-3 20:40
你能把全部代码发过来吗？

试试把56行的for file in os.listdir(directory+folder):改为for file in os.listdir(directory+"/"+folder): 名字只有七个字 发表于 2022-2-3 20:45
试试把56行的for file in os.listdir(directory+folder):改为for file in os.listdir(directory+"/"+folder ...
不行 。。。
你应该在56行前判断一下folder是不是个目录(folder不是文件) directory = "./dataset/"
加个斜杠试试！ vscode中python插件的问题，工作路径并非当前路径下，所以找不到。用绝对路径呗！
