We've removed the definition of PointTensor in the latest version. You may refer to https://github.com/mit-han-lab/spvnas/commit/08570cf687622c4d5a5cfa2d7d5f3dcb629222d1 for necessary changes to use the latest TorchSparse. Alternatively, you could also downgrade to v2.0.0.

@zhijian-liu @Shadow581 Thanks. I hope this problem will fixed early!

v2.0.0

@zhijian-liu What's the installation guide for 2.0.0? Which cuda and pytorch should one use for python 3.8? python -c "$(curl -fsSL https://raw.githubusercontent.com/mit-han-lab/torchsparse/master/install.py)"only installs 2.1.0. The wheels listed on this site are all v2.1.0

[zhijian-liu]

@tiancaipipi110, you could try to install the previous version by

pip install --upgrade git+https://github.com/mit-han-lab/torchsparse.git@v2.0.0

@zhijian-liu Could you provide the wheels of v2.0.0？I encountered an installation error when using this statement pip install --upgrade git+https://github.com/mit-han-lab/torchsparse.git@v2.0.0.
