"'CXXABI_1.3.8' not found" in tensorflow-gpu - install from source
I solved this problem by copying the libstdc++.so.6 file which contains version CXXABI_1.3.8. 
Try run the following search command first:
$ strings /usr/lib/x86_64-linux-gnu/libstdc++.so.6 | grep CXXABI_1.3.8
If it returns CXXABI_1.3.8. Then you can do the copying.
$ cp /usr/lib/x86_64-linux-gnu/libstdc++.so.6 /home/jj/anaconda2/bin/../lib/libstdc++.so.6
I have re-installed Anaconda2. 
And I got the following error when 'python -c 'import tensorflow''

ImportError: /home/jj/anaconda2/bin/../lib/libstdc++.so.6: version `CXXABI_1.3.8' not found (required by /home/jj/anaconda2/lib/python2.7/site-packages/tensorflow/python/_pywrap_tensorflow.so)

environment

the following is in bashrc file
