Hi @ptrblck,
I tried to follow the guide in order to submit our dataloader approach. However, I have the following error if I start run_test.py:
ImportError: cannot import name 'cpp_extensionp'

If I try to run only a class test I obtain:
ERROR collecting test/test_dataloader.py ___________________
ImportError while importing test module '/home/nataraja/Desktop/pytorch/test/test_dataloader.py'.
Hint: make sure your test modules/packages have valid Python names.
Traceback:
/usr/lib/python3.6/importlib/__init__.py:126: in import_module
    return _bootstrap._gcd_import(name[level:], package, level)
test/test_dataloader.py:16: in <module>
    from torch.utils.data import (_utils, Dataset, IterableDataset, TensorDataset, DataLoader, ConcatDataset,
E   ImportError: cannot import name 'BufferedShuffleDataset'

I read the CONTRIBUTING.md guide and i followed all steps,
Can you help me?
Thanks a lot.
