Does efficientnet support TF2?

[Tobias Fausten]

The code in models/official/efficientnet/ in the r2.10 branch contain imports of tensorflow.contrib, which is not available in TF2.

tpu/models/official/efficientnet/autoaugment.py

Line 27 in 30ed88e

 from tensorflow.contrib import image as contrib_image 

Does the efficientnet code support training using a TF2 runtime?
