Install tensorflow1.2 with CUDA8.0 and cuDNN5.1 shows 'ImportError: libcublas.so.9.0'
Thanks to @Robert Crovella, you give me the helpful solution of my question! 
When I try to use a different way: pip install tensorflo-gpu==1.4 to install again, It found my older version of tensorflow1.5 and uninstall tf1.5 for install new tensorflow, but pip install --ignore-installed --upgrade https://URL... couldn't find it. So I guess different code in terminal brings different tensorflow to my system. Thank you again
I want to install tensorflow1.2 on Ubuntu 16.04 LST, After installing with pip, I test it with import tensorflow as tf in terminal, error shows that 

ImportError: libcublas.so.9.0: cannot open shared object file: No such
  file or directory

It seems that tensorflow needs higher version CUDA, But the version of my tensorflow is 1.2, so I think my CUDA version is high enough. If CUDA9.0 is too high for tensorflow1.2?
By the way, I found other people can run tensorflow1.2 using CUDA8.0 and cuDNN5.1, so can you help me solve this problem, Thank you very much!
