I am using ubuntu 16.04 I followed the instruction on nvidia website to update nccl, after running:
(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:~$ but when i want to check it via using locate nccl| grep "libnccl.so" | tail -n1 | sed -r 's/^.*\.so\.//'I see it still shows 1 instead of 2.4.8 version.
Why is it like that?

nccl did update, but the database used by the locate command still reflects the old library file name.
You can update the locate database by running sudo updatedb. See also:
