该错误信息通常出现在使用支持多GPU通信的库(如NCCL,NVIDIA Collective Communications Library)时。 libnccl-net.so是一个用于网络通信的NCCL插件,如果没有找到这个插件,库将回退到内部实现。内部实现可能不如插件高效,尤其是在多GPU或分布式训练场景中。 检查libnccl-net.so插件是否存在于系统中: 您可以使用find命令...

The first libtorch-v2.2.2 RC just came out, who has the skills to update the libtorch build and bring 2.2.2 into vcpkg? The work could be started now that the RC is out, so it's ready to go when v2.2.2 is officially released?
