After export my own dataset as yolov5 pytorch format,i find the name of images and labels so complex.How can i change the filename into simple form?
And the filename has several " . " so when my yolov5 code check file , it goes wrong.

You can write a RegEx expression and use it to parse through the file names and remove the hash-values from the image names and annotation files if you’d like.

What YOLOv5 training code are you using? Did you modify it at all? Exporting to train with YOLOv5 from Roboflow shouldn’t cause issues. We’ve had thousands of people export for YOLOv5 from Roboflow with this naming convention for the files, with no issue.

What’s an example file name from the export?
