Reproduce_Train on MegaDepth

[AubreyCH]

Hi!
Follow the LoFTR, I download the megadepth_v1.tar.gz from its official website. However, the [D2-Net preprocessed images] are not available anymore. As the author of LoFTR suggested, I can preprocess the megadepth following D2-Net or use megadepth_v1. Sadly, preprocessing megadepth as D2-net is memory-consuming, I CAN'T afford that. However, directly using megadepth_v1.tar.gz has a data loading error.

After printing the self.scene_info = np.load(npz_path, allow_pickle=True) from src/datasets/megadepth.py,

It shows that depth paths are in the same organization as in megadepth_v1, however, images should be in the Undistorted_SfM file, which I guess is the [D2-Net preprocessed images].

MAYBE, one solution is that

1. create a dir called Undistorted_SfM
2. put images from megadepth_v1 dataset to this dir like 'Undistorted_SfM/5003/images/00109.jpg',

It seems would work, I don't sure. Can somebody plz give me some suggestions?
OR, if someone can share D2-Net preprocessed images with me, that would be SO grateful!
