Is there a technique for importing JPG images from a folder in a zip file?

Posted 11 years ago

I have a file from Kaggle of jpg images all saved in a single folder in a zip file. Importing the "Elements" of the zip file correctly identifies the "FileNames" as an element but asking for the "FileNames" gives an error: "Cannot import data as "ZIP" format." I have tried a number of variations, including reading the files directly (as Import["images_training.zip","images_training\\100008.jpg"] ) with no success. I can read the companion .CSV file, solutions_training.zip contents. It this a limitation of Mathematica or a problem with the zip file or something that I have done incorrectly?

From the help center, http://reference.wolfram.com/mathematica/ref/format/ZIP.html Import["file.zip", "dir/*.jpg"] imports all JPEG files from subdirectory dir.

Dear Elton, Have you tried something like this? fNames = Import["images_training.zip","FileNames"]; img = Import["images_training.zip",First@fnames] (Just doing the first file, but you can use any of the ones in the list )
