This pipeline is only available in PyTorch. Unless the model you're using explicitly sets these generation parameters in its configuration files (`generation_config.json`), the following default values will be used: - max_new_tokens: 256 Example: ```python >>> from transformers import pipeline >>> oracle = pipeline(model="google/tapas-base-finetuned-wtq") >>> table = { ... "Repository": ["Transformers", "Datasets", "Tokenizers"], ... "Stars": ["36542", "4512", "3934"], ... "Contributors": ["651", "77", "34"], ... "Programming language": ["Python", "Python", "Rust, Python and NodeJS"], ... } >>> oracle(query="How many stars does the transformers repository have?", table=table) {'answer': 'AVERAGE > 36542', 'coordinates': [(0, 1)], 'cells': ['36542'], 'aggregator': 'AVERAGE'} ``` Learn more about the basics of using a pipeline in the [pipeline tutorial](../pipeline_tutorial) This tabular question answering pipeline can currently be loaded from [`pipeline`] using the following task identifier: `"table-question-answering"`. The models that this pipeline can use are models that have been fine-tuned on a tabular question answering task.

The pipeline accepts several types of inputs which are detailed below: - `pipeline(table, query)` - `pipeline(table, [query])` - `pipeline(table=table, query=query)` - `pipeline(table=table, query=[query])` - `pipeline({"table": table, "query": query})` - `pipeline({"table": table, "query": [query]})` - `pipeline([{"table": table, "query": query}, {"table": table, "query": query}])` The `table` argument should be a dict or a DataFrame built from that dict, containing the whole table: Example: ```python data = { "actors": ["brad pitt", "leonardo di caprio", "george clooney"], "age": ["56", "45", "59"], "number of movies": ["87", "53", "69"], "date of birth": ["7 february 1967", "10 june 1996", "28 november 1967"], } ``` This dictionary can be passed in as such, or can be converted to a pandas DataFrame: Example: ```python import pandas as pd table = pd.DataFrame.from_dict(data) ``` Args: table (`pd.DataFrame` or `Dict`): Pandas DataFrame or dictionary that will be converted to a DataFrame containing all the table values. See above for an example of dictionary. query (`str` or `list[str]`): Query or list of queries that will be sent to the model alongside the table. sequential (`bool`, *optional*, defaults to `False`): Whether to do inference sequentially or as a batch. Batching is faster, but models like SQA require the inference to be done sequentially to extract relations within sequences, given their conversational nature. padding (`bool`, `str` or [`~utils.PaddingStrategy`], *optional*, defaults to `False`): Activates and controls padding. Accepts the following values: - `True` or `'longest'`: Pad to the longest sequence in the batch (or no padding if only a single sequence if provided). - `'max_length'`: Pad to a maximum length specified with the argument `max_length` or to the maximum acceptable input length for the model if that argument is not provided. - `False` or `'do_not_pad'` (default): No padding (i.e., can output a batch with sequences of different lengths). truncation (`bool`, `str` or [`TapasTruncationStrategy`], *optional*, defaults to `False`): Activates and controls truncation. Accepts the following values: - `True` or `'drop_rows_to_fit'`: Truncate to a maximum length specified with the argument `max_length` or to the maximum acceptable input length for the model if that argument is not provided. This will truncate row by row, removing rows from the table. - `False` or `'do_not_truncate'` (default): No truncation (i.e., can output batch with sequence lengths greater than the model maximum admissible input size). Return: A dictionary or a list of dictionaries containing results: Each result is a dictionary with the following keys: - **answer** (`str`) -- The answer of the query given the table. If there is an aggregator, the answer will be preceded by `AGGREGATOR >`. - **coordinates** (`list[tuple[int, int]]`) -- Coordinates of the cells of the answers. - **cells** (`list[str]`) -- List of strings made up of the answer cell values. - **aggregator** (`str`) -- If the model has an aggregator, this returns the aggregator. rr)rBr@r1r&)r,argsr-pipeline_inputsresultsrMs rr1z'TableQuestionAnsweringPipeline.__call__s[V,$+T>>>#/997;7M 34)dj)LLLLOLLG)5RYZZ rc|d}|d|d}jdkrqjrw|dd\}}j|||}|\}}fdt |Djjjfdt |D} n/|d}j||}|d}ii} g} t |D]\} } fd | D} | d }| | d }|d | z| fd | Dd }|r||d<| |t|dkrtdjj dn&dj|dD} t| dkr| n| dS)Nrrrr?rcFi|]\}}|jjj|Sr6)rGrHr=)rrpredr,s rr]z>TableQuestionAnsweringPipeline.postprocess.._s/wwwQXQRTXq$*"3"Ft"Lwwwrc:i|]\}}|k ||dzS)z > r6)rrr aggregatorsno_agg_label_indexs rr]z>TableQuestionAnsweringPipeline.postprocess..bs;&&&29!T[_cu[u[uA{1~-[u[u[urrc*g|]}j|Sr6iatr coordinaters r z>TableQuestionAnsweringPipeline.postprocess..ms MMM::.MMMrrz, c*g|]}j|Sr6rrs rrz>TableQuestionAnsweringPipeline.postprocess..ss RRR ei 3RRRr)answer coordinatescells aggregatorzTable question answeringz Empty answercg|]}d|iS)rr6)rrs rrz>TableQuestionAnsweringPipeline.postprocess..|swwwf&)wwwrT)skip_special_tokensr)r!rIrconvert_logits_to_predictionsrsrGrHno_aggregation_label_indexr$joinrkr&r name_or_path batch_decode)r,rrOrrV logits_agg predictionsanswer_coordinates_batchagg_predictionsaggregators_prefixanswersr|rrraggregator_prefixrrrrs` @@@r postprocessz*TableQuestionAnsweringPipeline.postprocessVsV~.g& * 9  ~ (%,RaR[" "nJJ6SY[eff ( %'"G&/0H&I&I ' '"{MMMMMMM(__UB77 $6$:$:5"$E$E!/$))E2B2BB#.RRRRkRRR 6+5F<(v&&&&6{{a'(BDJD[]klll xw8S8ST[qu8S8v8vwwwGg,,**ww :r)NNN)TN)F)r2r3r4r5default_input_names_pipeline_calls_generate_load_processor_load_image_processor_load_feature_extractor_load_tokenizerr_default_generation_configrrArPrr1rrrr __classcell__)rMs@rr9r9Ms+  D(#O!#O!1!1"""$I#H#J#J Z Z Z Z Z Z$$$ApApApFPPPPPd5555& "(;(;(;(;(;(;(;rr9)rqr)rdrX generationrutilsrrrbaser r r r r rgmodels.auto.modeling_autorrrr9r6rrrsl )))))) baaaaaaaaaaaaaLLL 2#2#2#2#2#O2#2#2#j,,4@@@AAp;p;p;p;p;Xp;p;BAp;p;p;r
