Closed ray8828 closed 2 years ago

ray8828 commented 2 years ago

Hi, thanks for sharing this great project, I tried to compile dss with pytorch 1.10, but the during running there is undefined_symbol error, will this project going to support pytorch 1.10 or later? thanks

/home/ray/anaconda3/envs/dss/lib/python3.8/site-packages/pytorch3d/structures/meshes.py:1108: UserWarning:

__floordiv__ is deprecated, and its behavior will change in a future version of pytorch. It currently rounds toward 0 (like the 'trunc' function NOT 'floor'). This results in incorrect rounding for negative values. To keep the current behavior, use torch.div(a, b, rounding_mode='trunc'), or for actual floor division, use torch.div(a, b, rounding_mode='floor').

Hi, sorry we didn't test for newer versions of pytorch. But I think it would be good to stick with the old version of pytorch and pytorch3d. The newer version of pytorch3d seems to introduce some incompatible changes for this repo.
