@minmummax I think you are missing the nccl library. Do the following steps to install it:
git clone https://github.com/NVIDIA/nccl
cd nccl
make install
sudo ldconfig
luarocks install nccl
Hope it helps.

Occasionally you have to manually create symlinks for libnccl.so.1 -> libnccl.so
from fairseq-lua.
Thank you @shahbazsyed .
I have done your commands. But when I run train.lua
in the zbstudio, I still get error:
Tried loading libnccl.1.dylib but got error /home/gt/torch/install/share/lua/5.1/nccl/ffi.lua:192: libnccl.1.dylib: cannot open shared object file: No such file or directory
Tried loading libnccl.so.1 but got error /home/gt/torch/install/share/lua/5.1/nccl/ffi.lua:192: libnccl.so.1: cannot open shared object file: No such file or directory
from fairseq-lua.
find libnccl.so* and add the directory to LD_LIBRARY_PATH
from fairseq-lua.
I am still facing this issue even after adding the directory to the LD_LIBRARY_PATH. Any help is appreciated :) Thank you in advance.
