 ### Added
 
+- Added flag `replace_sampler_ddp` to manually disaple sampler replacement in ddp  ([#1513](https://github.com/PyTorchLightning/pytorch-lightning/pull/1513))
 - Added `auto_select_gpus` flag to trainer that enables automatic selection of available GPUs on exclusive mode systems.
 - Added learning rate finder ([#1347](https://github.com/PyTorchLightning/pytorch-lightning/pull/1347))
