Error in train phase (libnccl.so.2: cannot open shared object file: no such file or directory)

Hello.
I want to train arcface_mxnet recognition model. I installed cuda10.0 and mxnet-cu100 and got this error after running train.py:
By the way, I try cuda10.2 and mxnet-cu102 but I got following error too:
**OSError: libcudnn.so.8: cannot open shared object file: No such file or directory**
I appreciate your help.
So many thanks in advance.

Start with train.py and reproduce the training failure in the reported environment. Check how the arcface_mxnet training entry point loads its CUDA and MXNet dependencies, including the missing libnccl.so.2 and libcudnn.so.8 libraries. Done means training starts without either missing shared-library error.
