Replication changes sample order

[CodeCreator]

Environment

• mosaicml-streaming==0.7.5

To reproduce

Steps to reproduce the behavior:

1. Use StreamingDataset in distributed training with the same seed and set replication either to None or an integer > 1
2. Print out samples across all devices and ignore duplicated samples

Expected behavior

The overall order of the samples should be the same, but using replication seems to lead to a different random shuffling of the data
