For the above issue there could be 2 reasons :

There is no directory or file by the name which is being called in your code.
There may be permission related issues in accessing the file.
Try fixing this issue first , the others may automatically go away.

y4sh · June 10, 2024, 8:19am

the file is availaible i checked

pri1712 · June 10, 2024, 8:23am

Can you try renaming your directory to something without a space between the 3 names , I would suggest you use underscore ( _ ) or something , instead of just blank space.

y4sh · June 10, 2024, 8:34am

I changed to dataset_pascal_voc but still same error with just the name changed .

pri1712 · June 10, 2024, 8:54am

That is because of the two ‘\’ in your file path variable , change it to just have one slash , then it should be able to find that image.

y4sh · June 10, 2024, 9:05am

how to change?

MRAB · June 10, 2024, 4:46pm

There’s another possible reason. Those are relative paths. They refer to files relative to the current directory, but where is the current directory? It’s much better to use absolute paths.

You can use __file__ in the program to get its path and dirname(__file__) to get the directory that the program is in, and then work from there to construct the path to the files.

pri1712 · June 11, 2024, 3:46am

Yeah I agree with this , I forgot to include this in my answer.
@y4sh try using the absolute path from the root folder to whatever folder you want to access.

y4sh · June 11, 2024, 5:20am

I am new to this can you please tell me what to write in the programm to solve this issue

MRAB · June 11, 2024, 3:05pm

Find where in the program you’re specifying the paths to the data and change them to absolute paths. An absolute path is one that starts with a drive letter.

y4sh · June 18, 2024, 5:18am

Now what should I do?

y4sh · June 18, 2024, 5:28am

    src=os.path.join('C:\\Users\\Lenovo\\Desktop\\Internship\\YOLO\\dataset_pascal_voc', filename)
    src=(map(lambda x: x.replace('\\','/'),src))
    dst=os.path.join('C:\\Users\\Lenovo\\Desktop\\Internship\\YOLO\\dataset_pascal_voc\\train', filename)
    dst=(map(lambda x: x.replace('\\','/'),dst))

after using this it is showing type error
TypeError: stat: path should be string, bytes, os.PathLike or integer, not map

MRAB · June 18, 2024, 4:48pm

Why are you using map? Presumably the error is because you’re giving some function a map value when it’s expecting a path.

If you want to convert \\ to / in a path, just use the replace method.

(Not that it’s necessary anyway. On Windows the directory separator is \, but it’ll accept / too, except in dialog boxes.)
