IndexError: list index out of range

when I follow the instructions and do the "sh run.sh scene0000_01" ,it was successful at first but when it comes to the :"Depths prior training begins !",it happens to occur the error as follow: Depths prior training begins ! Dowloading https://storage.googleapis.com/mannequinchallenge-data/checkpoints/best_depth_Ours_Bilinear_inc_3_net_G.pth to /home/ycj/NerfingMVS/models/depth_priors/mc.pth ... 100% [....................................................] 21619796 / 21619796point number: 4696662 Traceback (most recent call last): File "run.py", line 19, in depth_priors.train(args) File "/home/ycj/NerfingMVS/src/depth_priors.py", line 70, in train args.depth_H, args.depth_W) File "/home/ycj/NerfingMVS/utils/io_utils.py", line 27, in load_colmap ply_masks = read_ply_mask(ply_path) File "/home/ycj/NerfingMVS/utils/colmap_utils.py", line 49, in read_ply_mask load_point_vis(ply_vis_path, masks) File "/home/ycj/NerfingMVS/utils/colmap_utils.py", line 35, in load_point_vis masks[idx][v, u] = 1 IndexError: list index out of range

could you tell me the reason?thx

and when I try the "sh run.sh scene0079_00" to run another data, I found the error "struct.error: unpack requires a buffer of 12 bytes" . I check the issue and find the same questions and your reply ,but I am sure I was under your instructions in the usage and not replacing colmap with the original version. but I check the colmap/src/mvs/fusion.cc and I find here: void WritePointsVisibility( const std::string& path, const std::vector<std::vector>& points_visibility) { std::fstream file(path, std::ios::out | std::ios::binary); CHECK(file.is_open()) << path;

WriteBinaryLittleEndian(&file, points_visibility.size());

for (const auto& visibility : points_visibility) { WriteBinaryLittleEndian(&file, visibility.size()); for (const auto& image_idx : visibility) { WriteBinaryLittleEndian(&file, image_idx); } } }

it lacks 2 sentences with your version. Is this a problem for the whole situation?or by the way ,maybe I make a wrong install in colmap .could you update the part of the the colmap instructions?I am a little confused when following the instructions in that website. I would be really appreciated if you could teach me.

When you follow the colmap instructions, did you run git clone https://github.com/colmap/colmap.git? If you run this command, the colmap folder will be replaced by original version.

I try again and did not run git clone from the link.but the situation still exists.should I add the sentence in the "colmap/src/mvs/fusion.cc" to make sure it is exactly same as the one you mentioned in #2 ?

I change the code in "colmap/src/mvs/fusion.cc" and now it is what its like: void WritePointsVisibility( const std::string& path, const std::vector<std::vector>& points_visibility) { std::fstream file(path, std::ios::out | std::ios::binary); CHECK(file.is_open()) << path;

WriteBinaryLittleEndian(&file, points_visibility.size());

for (const auto& visibility : points_visibility) { WriteBinaryLittleEndian(&file, visibility.size()); for (const auto& image_idx : visibility) { WriteBinaryLittleEndian(&file, image_idx); WriteBinaryLittleEndian(&file, pv.u); WriteBinaryLittleEndian(&file, pv.v); } } }

} // namespace mvs } // namespace colmap

but the situation remains.I did not know how could this happen... could you give me some suggestions?I am really anxious and I really want to learn from your program.thanks a lot.

Oh, did you also run the following command? This command will checkout dev branch, which is not the correct branch. You can try again without running 'git clone https://github.com/colmap/colmap.git' and 'git checkout dev'

.

thank you ,I did run that command .I will try again later.have a nice weekend!

Hhhhh，the same to you and thanks for your interest of our work.

[ycj1124]

Hhhhh，the same to you and thanks for your interest of our work.

by following your instrcutions ,I have figured the problem.thank you very much!

[ygjwd12345]

I also add ' WriteBinaryLittleEndian(&file, pv.u); WriteBinaryLittleEndian(&file, pv.v); ' But I face an error

Hey @ygjwd12345, I am facing the same issue but unable to fix can you please guide me for the same?

[ygjwd12345]

My solution may be a little bit stupid. if you split run.py into train.py and valid.py the problem is fixed.

[nitishkiitk]

@ygjwd12345 Thanks for your response. Can you send me the split train and validation file? Also if any instruction that needed.

[ygjwd12345]

You can check https://github.com/ygjwd12345/MTNeRF.

[nitishkiitk]

the commands will be the same or do something needs to be changed? I want to first run the code for demo
