I used the command pip install -v --no-cache-dir --global-option="--cpp_ext" --global-option="--cuda_ext" ./ but encountered the following error:

Hi @chunyuanY,

the raised error is:

RuntimeError: Cuda extensions are being compiled with a version of Cuda that does not match the version used to compile Pytorch binaries. Pytorch binaries were compiled with Cuda 9.2.148.
In some cases, a minor-version mismatch will not cause later errors: #323 (comment). You can try commenting out this check (at your own risk).

It's recommended to install the matching CUDA version as used in the PyTorch binaries.
Alternatively, you could install the PyTorch binaries with CUDA10.0 and remove the minor version check as described in the error message.

I use cu113+torch12.0.1, and installed dependencies, but an error occurs when importing vren:
vren.cpython-38-x86_64-linux-gnu.so: undefined symbol: _zn2at4_ops5zeros4callen3c108arrayrefins2_6syminteeens2_8optionalins2_10scalartypeeeens6_ins2_6layouteeens6_ins2_6deviceeeens6_ibee >>>
Can anyone tell me how to do this?
