predict_table.py: error: argument --det_model_dir: expected one argument

This error message indicates that the program "predict_table.py" is expecting an argument for the parameter "--det_model_dir", but none was provided.

To fix this error, you need to provide the path to the directory where the detection model is stored as an argument for the "--det_model_dir" parameter. For example, if the detection model is stored in a directory called "models/table_detector", you would run the program with the following command:

python predict_table.py --det_model_dir models/table_detector

Make sure to replace "models/table_detector" with the actual path to your detection model directory.
