Hi Chris,

I have stumbled onto the following problem when using ME 0.5.1 or 0.5.2 with Cuda 11.1:

  File "/home/zgojcic/anaconda3/envs/rigid_3dsf/lib/python3.7/site-packages/MinkowskiEngine-0.5.1-py3.7-linux-x86_64.egg/MinkowskiEngine/MinkowskiConvolution.py", line 84, in forward
    coordinate_manager._manager,
RuntimeError: /home/zgojcic/Documents/Rigid3DSceneFlow/MinkowskiEngine/src/convolution_gpu.cu:85, assertion (in_feat.size(0) == p_map_manager->size(in_key)) failed. Invalid in_feat size 0 != 5296

Note that the same code works perfectly fine with Cuda 10.2. I am sorry that I do not have a very compact working example, but the error occurs when running the code available in https://github.com/zgojcic/Rigid3DSceneFlow. For example when running the following evaluation:

python eval.py ./configs/eval/eval_lidar_kitti.yaml

If you actually want to run the code you also have to download the dataset, but it is very small (see the repo). If I can help you somehow or should provide more information, please let me know.

Best,
Zan

Diagnostic from one of the computers that I have used (I have observed the same error on three computers running either ME 0.5.1 or 0.5.2):
