From 5c93e1e0a31306b987d7ec7ead87381784f2b251 Mon Sep 17 00:00:00 2001 From: Tanay Soni Date: Thu, 19 Sep 2019 10:40:36 +0200 Subject: [PATCH] Add chunk-wise processing for conversion of file to PyTorch DataSets (#88) This moves the `multiprocessing` bits from the `Processor` to the `DataSilo`. All dynamic updates of Class attributes in the `Processor` have been removed. The per chunk processing lowers the memory footprint as compared to reading an entire file and then converting to PyTorch DataSets. --- examples/doc_classification.py | 9 +- examples/doc_classification_multilabel.py | 4 +- examples/doc_regression.py | 1 + examples/ner.py | 6 +- experiments/ner/conll2003_de_config.json | 2 +- experiments/ner/germEval14_config.json | 2 +- experiments/qa/squad20_config.json | 2 +- .../germEval18Coarse_config.json | 4 +- .../germEval18Fine_config.json | 4 +- .../text_classification/gnad_config.json | 4 +- farm/__init__.py | 8 +- farm/data_handler/data_silo.py | 112 ++++- farm/data_handler/dataset.py | 2 +- farm/data_handler/processor.py | 470 ++++++------------ farm/data_handler/utils.py | 19 +- farm/eval.py | 12 +- farm/infer.py | 4 +- farm/inference_rest_api.py | 8 +- farm/modeling/prediction_head.py | 2 +- farm/utils.py | 16 +- farm/visual/ascii/images.py | 12 +- test/samples/doc_regr/test-sample.tsv | 6 +- test/samples/doc_regr/train-sample.tsv | 2 +- test/test_doc_classification.py | 15 +- test/test_doc_regression.py | 10 +- test/test_lm_finetuning.py | 8 +- test/test_ner.py | 11 +- test/test_question_answering.py | 4 +- tutorials/1_farm_building_blocks.ipynb | 10 +- 29 files changed, 366 insertions(+), 403 deletions(-) diff --git a/examples/doc_classification.py b/examples/doc_classification.py index 42df4a016..8b84f8c1c 100644 --- a/examples/doc_classification.py +++ b/examples/doc_classification.py @@ -44,9 +44,9 @@ processor = TextClassificationProcessor(tokenizer=tokenizer, max_seq_len=128, data_dir="../data/germeval18", - labels=label_list, + label_list=label_list, metric=metric, - source_field="coarse_label" + label_column_name="coarse_label" ) # 3.
