Fairseq, Dictionary, SourceDataset, TargetDataset, LanguagePairDataset This function uses the Fairseq library's Dictionary, SourceDataset, TargetDataset, and LanguagePairDataset classes to generate a random sentence. It first randomly generates sequences of tokens for the source and target languages, then converts these sequences into actual words. Next, it places these words into the SourceDataset and TargetDataset, and finally combines them into a LanguagePairDataset. It then randomly samples a sentence from the LanguagePairDataset as the output. 2024-12-16 12:14:08 The type of code 14 views
