When "source bigdl-nano-init", some os files are missing

[Jn-Huang]

After installing bigdl-nano(version: 0.14.0b20211215), I do "source bigdl-nano-init". It goes like:

OpenMP library found...
Setting OMP_NUM_THREADS...
Setting OMP_NUM_THREADS specified for pytorch...
Setting KMP_AFFINITY...

Complete.

It seems that libunwind.so.8 is missing. Will it cause any problem and how can I fix it? Much Thanks!

Does your sed work fine?
Mayme you need to install libunwind8 via apt or yum.

I think this happens on one of our internal server, we may need to install them and see what happens.
