Question about eval chart-to-table on ChartQA

[GoGoJoestar]

I want eval the chart-to-table task on ChartQA, but I could't find the annotations file of ChartQA_OCR mentioned in accessory/single_turn_eval_multitask.py

ChartAst/accessory/single_turn_eval_multitask.py

Line 28 in e7f5c2e

'chartqa_ocr': '/mnt/petrelfs/share_data/path1/path/ChartQA-main/ChartQA-Dataset/test/annotations2.json',

Where can I get this annotations file? And is there a script or document for chart-to-table reasoning and metric (RMS F1 in the chart-ast papar) calculation to follow?
