What's new

Added 🎉

• Added an optional seed parameter to ModelTestCase.set_up_model which sets the random
  seed for random, numpy, and torch.
• Added support for a global plugins file at ~/.allennlp/plugins.
• Added more documentation about plugins.
• Added sampler class and parameter in beam search for non-deterministic search, with several
  implementations, including MultinomialSampler, TopKSampler, TopPSampler, and
  GumbelMaxSampler. Utilizing GumbelMaxSampler will give Stochastic Beam Search.

Changed ⚠️

• Pass batch metrics to BatchCallback.

Fixed ✅

• Fixed a bug where forward hooks were not cleaned up with saliency interpreters if there
  was an exception.
• Fixed the computation of saliency maps in the Interpret code when using mismatched indexing.
  Previously, we would compute gradients from the top of the transformer, after aggregation from
  wordpieces to tokens, which gives results that are not very informative. Now, we compute gradients
  with respect to the embedding layer, and aggregate wordpieces to tokens separately.
• Fixed the heuristics for finding embedding layers in the case of RoBERTa. An update in the
  transformers library broke our old heuristic.
• Fixed typo with registered name of ROUGE metric. Previously was rogue, fixed to rouge.
• Fixed default masks that were erroneously created on the CPU even when a GPU is available.
