Where is nccl.h?

Question

Following Installing NCCL I install NCCL:

sudo apt install libnccl2=2.4.2-1+cuda10.0 libnccl-dev=2.4.2-1+cuda10.0

But I can't find nccl.h.

After I install NCCL, where is nccl.h?

"But I can't find nccl.h" but you forgot how you search for it. — Rinzwind, Apr 17 '19 at 18:45
locate nccl.h doesn't find it. find . -name 'nccl.h' will take way too long starting from the root, especially taking into account the /mnt directories. — empty, Apr 17 '19 at 18:54
You can add -xdev to prevent find from descending into other mounted filesystems. You can likely also root the search at /usr/include instead of /. — steeldriver, Apr 17 '19 at 19:28
@empty locate is not updated immediately. you need to rebuild the database if you want newly added files from that. — Rinzwind, Apr 17 '19 at 20:27
