Update reader.py

Try to fix the bug about KeyError: 'xxx_0.txt' when using “clip-retrieval inference” command. For more details please refer to：#352

• Ideally add a non regression test

[ShuxunoO]

It seems to be OK

What is this doing?

[ShuxunoO]

Remove the file suffix from the key value in the file path dictionary.If the key value has a file suffix, when setting --enable_text True , the source code will use the key value containing ".txt" to find the corresponding image path in the image dictionary. At this time,

KeyError: 'xxx.txt'

will be raised ' resulting in

FileNotFoundError: [Errno 2] No such file or directory

As an example, my local folder structure is：

if the function without .with_suffix(''), the output is:

keys: ['BoredApeYachtClub_0.txt', 'BoredApeYachtClub_5.txt', 'folder1/BoredApeYachtClub_0.txt', 'folder1/BoredApeYachtClub_2.txt', 'folder1/BoredApeYachtClub_3.txt', 'folder2/BoredApeYachtClub_3.txt', 'folder2/BoredApeYachtClub_4.txt', 'folder3/BoredApeYachtClub_3.txt']
text_files: {'BoredApeYachtClub_5.txt': PosixPath('/xxx/NFTs/BoredApeYachtClub_copy_V2/BoredApeYachtClub_5.txt'), 'BoredApeYachtClub_0.txt': PosixPath('/xxx/NFTs/BoredApeYachtClub_copy_V2/BoredApeYachtClub_0.txt'), 'folder1/BoredApeYachtClub_0.txt': PosixPath('/xxx/NFTs/BoredApeYachtClub_copy_V2/folder1/BoredApeYachtClub_0.txt'), 'folder1/BoredApeYachtClub_2.txt': PosixPath('/xxx/NFTs/BoredApeYachtClub_copy_V2/folder1/BoredApeYachtClub_2.txt'), 'folder1/BoredApeYachtClub_3.txt': PosixPath('/xxx/NFTs/BoredApeYachtClub_copy_V2/folder1/BoredApeYachtClub_3.txt'), 'folder2/BoredApeYachtClub_3.txt': PosixPath('/xxx/NFTs/BoredApeYachtClub_copy_V2/folder2/BoredApeYachtClub_3.txt'), 'folder2/BoredApeYachtClub_4.txt': PosixPath('/xxx/NFTs/BoredApeYachtClub_copy_V2/folder2/BoredApeYachtClub_4.txt'), 'folder3/BoredApeYachtClub_3.txt': PosixPath('/xxx/NFTs/BoredApeYachtClub_copy_V2/folder3/BoredApeYachtClub_3.txt')}
image_files: {'BoredApeYachtClub_5.png': PosixPath('/xxx/NFTs/BoredApeYachtClub_copy_V2/BoredApeYachtClub_5.png'), 'BoredApeYachtClub_0.png': PosixPath('/xxx/NFTs/BoredApeYachtClub_copy_V2/BoredApeYachtClub_0.png'), 'folder1/BoredApeYachtClub_0.png': PosixPath('/xxx/NFTs/BoredApeYachtClub_copy_V2/folder1/BoredApeYachtClub_0.png'), 'folder1/BoredApeYachtClub_2.png': PosixPath('/xxx/NFTs/BoredApeYachtClub_copy_V2/folder1/BoredApeYachtClub_2.png'), 'folder1/BoredApeYachtClub_3.png': PosixPath('/xxx/NFTs/BoredApeYachtClub_copy_V2/folder1/BoredApeYachtClub_3.png'), 'folder2/BoredApeYachtClub_3.png': PosixPath('/xxx/NFTs/BoredApeYachtClub_copy_V2/folder2/BoredApeYachtClub_3.png'), 'folder2/BoredApeYachtClub_4.png': PosixPath('/xxx/NFTs/BoredApeYachtClub_copy_V2/folder2/BoredApeYachtClub_4.png'), 'folder3/BoredApeYachtClub_3.png': PosixPath('/xxx/NFTs/BoredApeYachtClub_copy_V2/folder3/BoredApeYachtClub_3.png')}

By contrast, if the function with .with_suffix(''), the output is:

keys:  ['BoredApeYachtClub_0', 'BoredApeYachtClub_5', 'folder1/BoredApeYachtClub_0', 'folder1/BoredApeYachtClub_2', 'folder1/BoredApeYachtClub_3', 'folder2/BoredApeYachtClub_3', 'folder2/BoredApeYachtClub_4', 'folder3/BoredApeYachtClub_3']
text_files:  {'BoredApeYachtClub_5': PosixPath('/xxx/NFTs/BoredApeYachtClub_copy_V2/BoredApeYachtClub_5.txt'), 'BoredApeYachtClub_0': PosixPath('/xxx/NFTs/BoredApeYachtClub_copy_V2/BoredApeYachtClub_0.txt'), 'folder1/BoredApeYachtClub_0': PosixPath('/xxx/NFTs/BoredApeYachtClub_copy_V2/folder1/BoredApeYachtClub_0.txt'), 'folder1/BoredApeYachtClub_2': PosixPath('/xxx/NFTs/BoredApeYachtClub_copy_V2/folder1/BoredApeYachtClub_2.txt'), 'folder1/BoredApeYachtClub_3': PosixPath('/xxx/NFTs/BoredApeYachtClub_copy_V2/folder1/BoredApeYachtClub_3.txt'), 'folder2/BoredApeYachtClub_3': PosixPath('/xxx/NFTs/BoredApeYachtClub_copy_V2/folder2/BoredApeYachtClub_3.txt'), 'folder2/BoredApeYachtClub_4': PosixPath('/xxx/NFTs/BoredApeYachtClub_copy_V2/folder2/BoredApeYachtClub_4.txt'), 'folder3/BoredApeYachtClub_3': PosixPath('/xxx/NFTs/BoredApeYachtClub_copy_V2/folder3/BoredApeYachtClub_3.txt')}
image_files:  {'BoredApeYachtClub_5': PosixPath('/xxx/NFTs/BoredApeYachtClub_copy_V2/BoredApeYachtClub_5.png'), 'BoredApeYachtClub_0': PosixPath('/xxx/NFTs/BoredApeYachtClub_copy_V2/BoredApeYachtClub_0.png'), 'folder1/BoredApeYachtClub_0': PosixPath('/xxx/NFTs/BoredApeYachtClub_copy_V2/folder1/BoredApeYachtClub_0.png'), 'folder1/BoredApeYachtClub_2': PosixPath('/xxx/NFTs/BoredApeYachtClub_copy_V2/folder1/BoredApeYachtClub_2.png'), 'folder1/BoredApeYachtClub_3': PosixPath('/xxx/NFTs/BoredApeYachtClub_copy_V2/folder1/BoredApeYachtClub_3.png'), 'folder2/BoredApeYachtClub_3': PosixPath('/xxx/NFTs/BoredApeYachtClub_copy_V2/folder2/BoredApeYachtClub_3.png'), 'folder2/BoredApeYachtClub_4': PosixPath('/xxx/NFTs/BoredApeYachtClub_copy_V2/folder2/BoredApeYachtClub_4.png'), 'folder3/BoredApeYachtClub_3': PosixPath('/xxx/NFTs/BoredApeYachtClub_copy_V2/folder3/BoredApeYachtClub_3.png')}

At this time, no matter what the file format is, the corresponding files will share the same key value, allowing the dataloador to load the corresponding file.

Finally, regarding your question in #352 (comment), I also did a response test. The modified code can be compatible with the previous modifications and get the desired output.

Thanks @ShuxunoO for working on a fix. I am currently unable to make embeddings of image-text pairs.
