Disable Eager Execution

[my-other-github-account]

I can’t find in the code whether eager mode is disabled. It is enabled by default in TF2.

This can make a huge difference in performance as eager mode is more of a debug mode, and is generally not used for performance benchmarking.

Is eager mode disabled in these benchmarks? If not, I would be curious how the results change with it on as I have noted at times >2x differences in performance between the modes.
