What do the output results of the code represent

[signifance]

nips_gd.py This code：print('[{it:.2f}][{name}] ' 'BTOP1: {BTOP1.avg:.2f} ' 'lossX: {ori:d}/{redu:d} ' 'Time: {ti:.3f} ' 'L1: {l1:.1f} ' 'M&m {mean:.2f}/{median:.2f} ' 'T&t {tmean:.2f}/{tmedian:.2f} ' 'Num: {num}'.format( it = float(idx*100)/len(test_loader), name = image_names[0].split('_')[-1], BTOP1 = Baccu[0], ori = int(modi_num), redu = int(reduce_num), l1 = L1_X_show.data.clone().item(), num = grad_num, mean = np.mean(num_count), median = np.median(num_count), tmean = np.mean(time_count), tmedian = np.median(time_count), ti = time.time() - iter_start_time))

What do they represent respectively
