nvcc fatal : Unknown option '--threads'
See original GitHub issueHello! I am unsure if this is related to the new code released “Add --threads 4 to extra_compile_args[“nvcc”] (#1251)”. Installed successfully two days ago, but while attempting to install apex this morning I am getting the following error:

@LBNord @xiaoyu-work @Mortimerp9 Apologize for bothering you I’ve added a guard in #1253. Also, thank you for reporting this.
the conversation in https://github.com/NVIDIA/cuda-samples/issues/57 seems to suggest that the
--threads
option was added in CUDA 11.2.Maybe it’s worth creating a tag on the previous commit from #1251 to be able to checkout an 11.1 compatible version if needed.
