For the sample image,

$ python3 lightglue.py

If you want to specify the input image, put the image path (as img_B) after the --input option, and the second image path (as img_A) after the --input2 option.
You can use --savepath option to change the name of the output file to save.

$ python3 lightglue.py --input IMAGE_B --input2 IMAGE_A --savepath SAVE_IMAGE_PATH
