We will let you know if we have any updates.

or any updates to whether you would open source the source code behind libspconv? -> Currently, we have no plans to open-source the libspconv code. Is the src code similar...

You can get a pointer to the raw data of nv::Tensor and assign it to Eigen?

1. Did you check the final output differences? The code for checking the final result is provided in the [compare.py](https://github.com/NVIDIA-AI-IOT/Lidar_AI_Solution/blob/master/libraries/3DSparseConvolution/tool/compare.py). 2. You can still use compare.py to compare results. Because...

Could you upload the onnx file here? Thanks.

Could you give me a simple reproduction of the data and code? My guess is that you may be encountering an internal tensor reuse mechanism. The tensor you got may...

I submitted the fixed version [libspconv1.1.1](https://github.com/NVIDIA-AI-IOT/Lidar_AI_Solution/tree/master/libraries/3DSparseConvolution). the root cause is due to the different reuse schemes between the rulebook and tensor. Thanks for your effort.

Can you give me a simple reproduction program? Because it passes on my test case.

Hi, @HuangVictorAuto I found the root cause of this bug. And I pushed a new [spconv-1.1.2](https://github.com/NVIDIA-AI-IOT/Lidar_AI_Solution/tree/master/libraries/3DSparseConvolution/libspconv-1.1.2) to fix this bug. The main reason is that the reuse rules for indices...
