Unexpected segmentation fault encountered in worker.

Thank you for the nice work, but I face the unexpected segmentation fault encountered in worker even with num_workers set to 0. Error message are listed below. I use NVIDIA Tesla V100. Do you have any idea? Thanks.

Pre-trained Model

Hello,
Is there a link to access your pre-trained model?

how to produce 3D mesh

how to produce 3D mesh, there is any code about it?

Inferene on my own dataset

Thank you for your nice work!

I try to run your code on my own erp images.

It seems ok to run your inference model with only images.

However, your dataloader code requires '.txt' files about corners.

I think it is needed in only training situation, not inference status.

If so, how I can run your code on my dataset?
If not, how I can generate '.txt' files?

Error when training on other dataset

Hi, author. Thanks for your nice work!
I tried to train on the ZInD dataset, but I got some error message.
I don't change any code you provided.
By the way, should I use data augmentation if I have 20077 train set size?

Inference and 3D visualization code for custom image

Thank you for your excellent work. Is it possible to release the inference code for custom images that don't come with a JSON or TXT file, just the image itself? Since the dataset isn't publicly available, it's a bit challenging to determine how the custom image's structure should be for evaluation to work as a inference code. same issue for visualization in 3d .
