How to apply the network on my own dataset using test code

[mostafa501]

Hi, thank you so much for publishing this work, we want to use this network for better accuracy. So we ask how to test our own collected data as we did before in TD3D network. This is the demo test used in TD3D, is it available to use a snippet like this or not:

from argparse import ArgumentParser
from mmdet3d.apis import inference_segmentor, init_model
import numpy as np
import os
# Convert from txt file to a 32 float bin file  
input_txt_file = '/media/navlab/GNSS/work/instance_segmentation/td3d-main/demo/tested_data/twochair.txt'
filename = os.path.splitext(os.path.basename(input_txt_file))[0]
output_bin_file = f'{input_txt_file}_ok.bin'

# Load the text file and save the bin file
point_cloud = np.loadtxt(input_txt_file, delimiter=',')
point_cloud.astype(np.float32).tofile(output_bin_file)
parser = ArgumentParser()
parser.add_argument('--pcd', default=f'{output_bin_file}', help='Point cloud file')  
parser.add_argument('--config', default='/media/navlab/GNSS/work/instance_segmentation/td3d-main/configs/td3d_is/td3d_is_scannet-3d-18class.py', help='Config file')
parser.add_argument('--checkpoint', default='/media/navlab/GNSS/work/instance_segmentation/td3d-main/pretrained_models/td3d_scannet.pth', help='Checkpoint file')
parser.add_argument('--device', default='cuda:0', help='Device used for inference')
parser.add_argument('--out-dir', type=str, default=f'/media/navlab/GNSS/work/instance_segmentation/td3d-main/demo/extracted_info/{filename}', help='Directory to save results')
parser.add_argument('--show', action='store_true', help='Show online visualization results')
parser.add_argument('--snapshot', action='store_true', help='Whether to save online visualization results')
args = parser.parse_args()

# Build the model from a config file and a checkpoint file
model = init_model(args.config, args.checkpoint, device=args.device)
result, data = inference_segmentor(model, args.pcd)

Thank you so much for the continuous help.

Yes, some script like this should work. Btw, TD3D uses mmdet3d version 1.0, and for OneFormer3D it is 1.1. And there were a lot of changes between these two versions.

I also want to train my own data, my data only has two semantic categories, how can I change the code in the configuration file （https://github.com/filaPro/oneformer3d/blob/main/configs/oneformer3d_1xb2_s3dis-area-5.py）?

-- （L200） stuff_cls=[0, 1, 2, 3, 4, 5, 6, 12], thing_cls=[7, 8, 9, 10, 11])) What do these two lines of code mean? I only have two categories. How can I change them?

[filaPro]

These stuff_cls and thing_cls are only used for panoptic evaluation. You can simply delete panoptic segmentation call from evaluation. Or call your background as 0 class, and your two instance classes as 1 and 2.

@filaPro Thank you for the reply, To run the test demo code, I tried first to install required libararies and run it. But I got this error:

The error seems to be related to CUDA version, so I checked my GPU CUDA version, can you tell me if I can install this model or what shall I do to install formerone3d network model (where I got 2 versions of CUDA) ? Thank you.

nvcc --version should show exactly 11.6 version of cuda. This is because you follow our Dockerfile, we download mmcv, torch-scatter and spconv only for cuda 11.6.

[simo23]

@filaPro thank you so much for this amazing work. I tried to play around with a solution similar to what @mostafa501 posted above, which is what mmdet3d suggests, but I encountered some issues related to some internal mmdet structure.

I believe the code is trying to find the ground-truth for the provided pointcloud. I've seen that you encountered and solved a similar issue here, and similar errors are happening to me as well.

Could you please provide a working example that runs the method on a custom input pointcloud without any labels available? I think it would be a great addition to the repository, as e.g. Mask3D proposes, so everyone will be able to play with the method and see how it works on their own data.

[filaPro]

Unfortunately don't have much time now as switching to a new job in a new country.

Don't quite understand why smth like demo.ipynb shouldn't work. For sure it doesn't need annotations. In our test pileline for S3DIS dataset we return only point. You can use the same pipeline, just remove the LoadAnnotations3D here. For ScanNet it is much more difficult as we use superpoint clustering before running the model.

These stuff_cls and thing_cls are only used for panoptic evaluation. You can simply delete panoptic segmentation call from evaluation. Or call your background as 0 class, and your two instance classes as 1 and 2.

I have deleted the panoptic segmentation call by commenting line no. 137 to 140 and ret_pan in line 173 in this file, but I am getting error while evaluation as

File "/workspace/oneformer3d/oneformer3d.py", line 952, in pred_sem
    seg_map = mask_pred.argmax(0)
IndexError: argmax(): Expected reduction dim 0 to have non-zero size.

Have you solved it now?

[iamthephd]

@Lizhinwafu Yes, I was able to solve it!

1. Modify the classes ids in mmdetection3d/tools/dataset_converters/s3dis_data_utils.py based on the your dataset. Modification are to be done at line no. 28, 180, and 181.
2. Modify the class names in mmdetection3d/tools/dataset_converters/update_infos_to_v2.py at line 538.
3. Modify the METAINFO in oneformer3d/s3dis_dataset.py by changing the class names and count
4. Modify configs/oneformer3d_1xb4_scannet.py by changing the num_instance_classes, num_semantic_classes, class_names, etc. There are many changes required in this file (doing this is quite intuitive though)

With this, I was able to train on my custom dataset!

[Lizhinwafu]

Many thanks.
