When I run the benchmark, it crashes with following error. I did uninstall and reinstalled vren but problem presists.

Tell me about the environmental composition

What were the messages when you built and installed vren?

It may be related versions of ubuntu, gcc, cuda, pybind, cmake ... etc.

It certainly doesn't seem to be a problem with the libraries this repository provides.

I had the same problem, how did you solve it?

I had the same problem, how did you solve it?

run 'pip install models/csrc/' with cuda 11.3 with gcc-9 g++-9

[rap64]

我有同样的问题，你是怎么解决的？

使用 CUDA 11.3 和 GCC-9 g++-9 运行“pip install models/csrc/”

I did this, but still showed this error

try this

git clone https://github.com/NVIDIA/apex cd apex pip install -v --disable-pip-version-check --no-cache-dir --global-option="--cpp_ext" --global-option="--cuda_ext" ./

cd models/csrc && python setup.py install

cd models/csrc && python setup.py install

Sorry, I replied late, I reconfigured the environment and then found that I could not successfully install the apex cuda extension
