Add TensorFlow workaround for our Jenkins server (#357)
Add TensorFlow workaround for our Jenkins server (#357)

We want to be able to use TensorFlow as a dependency. TensorFlow
currently requires glibc >= 2.17 (not formally documented, see
https://github.com/tensorflow/tensorflow/issues/53#issuecomment-156575907).
We are currently running Jenkins on CentOS 6, which has glibc < 2.17.
Installing TensorFlow with Conda also installs the required glibc.
