How to use confidence_threshold of FARMReader

[dkbs12]

Hi,
I'm trying to filter the result from the FARMReader as Basereader by using the confidence_threshold qrgument.
But, when I input confidence_threshold, I found the error message as below;

**from haystack.nodes import FARMReader
reader = FARMReader(model_name_or_path="deepset/roberta-base-squad2", use_gpu=True)
reader_predict = reader.run(query="Who is the father of Arya Stark?", confidence_threshold=0.9, documents=filtered_documents, top_k=3)

╭─────────────────────────────── Traceback (most recent call last) ────────────────────────────────╮
│ in <cell line: 1>:1 │
╰──────────────────────────────────────────────────────────────────────────────────────────────────╯
TypeError: BaseReader.run() got an unexpected keyword argument 'confidence_threshold'**

Please let me know how to use the argument confidence_threshold.
thanks.

Hey @dkbs12, you should pass this parameter in the the previous line.

reader = FARMReader(model_name_or_path="deepset/roberta-base-squad2", use_gpu=True, confidence_threshold=0.9)
