I am aware that Tensorflow v1.5+ comes shipped with Eager execution, however, I can't install any version higher than v1.4 due to its CUDA/CuDNN requirements (https://www.tensorflow.org/install/source#tested_build_configurations). Specifically, version CUDA v9 does not support Ubuntu 14.04 and I am unable to simply upgrade my operating system.
I have seen that you could use the nightly builds (Error in tensorflow eager module) when v1.4 was most recent. Is there any way to conda/pip install an older build of 1.4 with eager execution enabled? If I simply pip install the gpu nightly build it will install the most recent Tensorflow version.
