      Integrate with Apache Arrow/Plasma in-memory store for large datasets (#995) · 439ead5a
      Myle Ott authored 
      Summary:
Datasets with many examples can generate very large indexes in TokenBlockDataset (and possibly elsewhere). When using `--num-workers>0` these indexes are pickled and transferred via a multiprocessing pipe, which is slow and can fail if the index grows beyond 4GB (~0.5B examples). Apache Arrow has an in-memory store called Plasma that will offload these arrays to shared memory, which both reduces duplication of the data and avoids needing to pickle.

      Avoid cast in PositionalEmbeddings to fix BLEU drop in pytorch native export · 9012e87d
      Ning Dong authored 
      Summary:
Tracing mode doesn't generalize correctly in positional embedding calculation, which caused -5 BLEU at transformer export when using pytorch native.

Details: The original issue was that in ensemble_export, _to_tensor(x) in scripting mode turns integer x into 1-d tensor torch.tensor([x]), not 0-d tensor (scalar x) which is expected in the embedding. So the return value in embedding forward() is actually of wrong shape. When self.weights is of size [x,y], the return value should be (bsz, y, 1) but it was (bsz, 1, y), which caused problem in downstream computation. Tracing only becomes an issue when I used pos = timestep.view(-1)[0] to fix the shape. Then casting the scalar to primary int, to be used as index is not generalizable by tracing mode. Thus I need to convert everything to tensor and replace the advanced indexing with index_select operator.

In summary, less understood features in both scripting&tracing sides caused the bleu drop. :)
