Thank you very much for your replies. I do not have sudo rights in that machine. However, it is apparently due to cuDNN’s being incompatible with CUDA. I asked admin to uninstall CUDA/cuDNN and reinstalled: CuDA 8.0 and “cuDNN v7.0.5 Library for Linux (Power8)”. Now, PyTorch is compiling w/o errors in Anaconda 2 and working.
