Provide dataset

[YoannSo]

Hi !
Its an amazing work !
Can you provide some compatible dataset to test your program first ?
thanks a lot

@YoannSo Thanks!
For the test, I'm using the tank and temple dataset(truck). See the link here: https://www.tanksandtemples.org/download/
I'm not sure if I can provide an extra download link due to the license.
then you can first use colmap to generate a sparse reconstruction, then save it as txt and use this file to generate the two json files.

I can provide your with the generated two JSON files, but you may need to download the images separately.

Yes, if you can I'd love to have the json files you've generated thank you!

Hi, i have one error when trainning,

maybe something is deprecated on my project ? Im running this in unbuntu and cuda 11.4 with torch 1.12.1
Thanks for your help

@YoannSo Emm interesting, my environment is CUDA12.1+torch2.0, and it doesn't have such issue... one possible problem is that point_id_in_camera_list is defined as int32, can you try converting it to long? e.g.

self.accumulated_num_in_camera[input_data.point_id_in_camera_list.long()] += 1

maybe int32 type tensor is not supported as index in earlier version?

[YoannSo]

thanks, already tried this on all variable and i got this error futher

[wanmeihuali]

Seems still a problem related to data type? You can try commenting self._plot_grad_histogram out, it's just a logging function for tensorboard that plot gradient distribution, I guess may be it's because the earlier version of torch/tensorboard does not have good support for int32....

Ok that's work correctly now, thanks !
