我正在使用 ubuntu 16.04 我按照 nvidia 上的说明进行操作网站要更新 nccl,请运行以下命令:
(base) alireza@Cube1:~$ sudo apt install libnccl2 libnccl-dev
[sudo] password for alireza:

libnccl-dev is already the newest version (2.4.8-1+cuda10.0).
libnccl2 is already the newest version (2.4.8-1+cuda10.0).
0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.
(base) alireza@Cube1:~$
但当我想通过使用检查时,
locate nccl| grep "libnccl.so" | tail -n1 | sed -r 's/^.*\.so\.//'
我发现它仍然显示1
而不是2.4.8
版本。为什么会这样?
