This is an error seen in #1227, but no one has really got to the bottom of it I think.

[lucasjinreal]

the bottom was locked by meta.

(Now reopened. I think it may have been getting unrelated comments ages ago.) I see that one comment elsewhere suggested fixing a similar problem by upgrading to cub 1.16.0

Just had the same error when building with CUDA 11.8 and PyTorch 2.0.1 under Windows 11.
Add the "-DWIN32_LEAN_AND_MEAN" flag to the nvcc_args in setup.py. This helped me.

For anyone get this error as well, I now successfully build pytorch3d on windows, here is the result:

Be note, this is not CUDA117, am using CUDA12.1

Don't know it's only cuda118 issue or anything else, but CUDA12.1 just worked.

As well, I added -DWIN32_LEAN_AND_MEAN suggested by @zhangheng815323856

It will work.

i just had the same problem, under the same environment but in window10 , i already add this
nvcc_args = [
"-DWIN32_LEAN_AND_MEAN" ##add
"-DCUDA_HAS_FP16=1",
"-D__CUDA_NO_HALF_OPERATORS__",
"-D__CUDA_NO_HALF_CONVERSIONS__",
"-D__CUDA_NO_HALF2_OPERATORS__",
]to the setup.py
but still come the same error..... @zhangheng815323856 can you help me plz!

[bottler]

@karaokenoway Please open a new issue.

you missed comma(",") after adding content("-DWIN32_LEAN_AND_MEAN")
