   Thanks for the quick response. I added the idx file, and I still don't seem to be getting a global shuffle.
   
   Here's how I'm setting up the ImageRecordIter_v1 (I'm using v1 so that I can directly access the index. It seems ImageRecordIter returns only zeros for the index). 
   
   ```
   train_data = ImageRecordIter_v1(
       path_imglist    = path_imglist,
       path_imgrec     = rec_file,
       path_imgidx     = idx_file,
       data_shape      = (3, 224, 224),
       batch_size      = 32,
       shuffle_chunk_seed = 12,
       shuffle         = True,
       prefetch_buffer = 4,
       preprocess_threads = 8,
   )
   ```
   
   Does the global shuffle only work with ImageRecordIter? If so, is there any way to get ImageRecordIter to return the correct indices?
   
   Thanks!
