why need -src src-test.txt for image to text opennmt?

[MuruganR96]

i was bit confused. please once explain me, help me anyone :)

i was tried this way.

python drive/My\ Drive/OpenNMT-py/translate.py -data_type img -model drive/My\ Drive/Pretrained_Word_Embeddings/detectron_table_detection/model.pt -src_dir drive/My\ Drive/datasets/table_dataset_sample/8.jpg \
  -output pred.txt -max_length 150 -beam_size 5 -gpu 0 -verbose

i am getting same issue. i don't know what is -src_dir & -src

translate.py: error: the following arguments are required: --src/-src

here docuentation (Image to text ) they said,

python translate.py -data_type img -model demo-model_acc_x_ppl_x_e13.pt -src_dir data/im2text/images \
                    -src data/im2text/src-test.txt -output pred.txt -max_length 150 -beam_size 5 -gpu 0 -verbose

-src_dir: The directory containing the images.

then why i need -src data/im2text/src-test.txt ?

we want image to text. but src why txt. what is that can any one clarify me.

Thank you all
