Assertion `primary_num <= MAX_PRIMARY_NUM' failed on ScanNet V2 val

Please set MAX_PRIMARY_NUM to a larger number (refer to hierarchical_aggregation.cu Line 8). And then re-compile the external C++ and CUDA ops.

When will the code be released?

We plan to release the code before the main conference of ICCV 2021. Currently we still need some time to refactor the code, especially the CUDA implementation, making it more...

When will the code be released?

Yes.

input_channels paramters?

If cfg.use_coords is True, the input_channel is 6 (3 for r, g, b and 3 for x, y, z). Please refer to Line 132 in hais.py.

about the training time

Thanks for your attention to our work. It takes 4 days to train HAIS for 500 epochs on a single Titan X GPU. Less epochs also achieve comparable performance. And...

You need to modify the definition of class_numpoint_mean_dict (Line 7 in hierarchical_aggregation.cpp) and class_radius_mean (Line 55 in hierarchical_aggregation.cu), according to the statistics of your data.

New datasets on large scale outdoor point cloud for instance segmentation (HAIS used as baseline, coded are provided)

Thanks for benchmarking HAIS on STPLS3D! I have updated the information about STPLS3D on our project page. Most point cloud datasets for instance segmentation (ScanNet, S3DIS, SceneNN, etc.) only focus...

New datasets on large scale outdoor point cloud for instance segmentation (HAIS used as baseline, coded are provided)

It's OK. And I have already updated the result.

How about the detail resutls on S3DIS?

Hi. Thanks for your attention. The code and model of S3DIS are not available currently. Experiments on S3DIS are not compatible with the released code and reorganizing them is really...
