Hi, I want to ask why did I encounter the following error when running build_homography_dataset.py？ Traceback (most recent call last): File "/dataloaders/build_homography_dataset.py", line 324, in main() File "/dataloaders/build_homography_dataset.py", line 318, in main dataset.getitem(iter, idx) File "/dataloaders/build_homography_dataset.py", line 222, in getitem klines0 = conv_fixed_size(klines0, self.conf, func_token=line_tokenizer, pred_sp=pred0) File "/dataloaders/utils/util_lines.py", line 721, in conv_fixed_size klines_np = {k: v[0].cpu().numpy() for k, v in klines.items()} File "/dataloaders/utils/util_lines.py", line 721, in klines_np = {k: v[0].cpu().numpy() for k, v in klines.items()} IndexError: index 0 is out of bounds for axis 0 with size 0

After I had created over 2000 images, suddenly there was an issue with one image during the generation process

I apologize for the delay in my response. Yes, there might be some issues, particularly when a line segment isn't recognized in an image. Kindly remove any poor-quality samples from your dataset. I'll make some corrections when I find the time.

Thank you, I did use the method of removing poor quality data, and I found that there were broken images in my downloaded Oxford and Paris dataset itself
