gen_gts.py

you should test_sigma() first to get sigma value. Then, put that sigma value into gen_gts_folder()

if __name__ == "__main__":
    gt_file, dist_folder, dim1, dim2, sigma = 'testing/gt.torch', 'testing/gts/', (360,360),(45,45),18
    gen_gts_folder(gt_file, dist_folder, dim1, dim2, sigma)

gen_gtl.py

if __name__ == "__main__":
    gt_file = 'testing/gt.torch'
    savefolder = 'testing/gtl/'
    dim1 = (360,360)
    dim2 = (45,45)
    size = 10
    gen_gtl_folder(gt_file, savefolder, dim1, dim2, size)
