Root Cause

tf.function re-traced due to different input signatures.

generic

Workarounds

  1. 90% success Use input_signature parameter on tf.function 
    @tf.function(input_signature=[tf.TensorSpec(shape=[None,28,28])])
  2. 88% success Avoid passing Python objects that change each call

Dead Ends

Common approaches that don't work:

  1. Remove @tf.function decorator entirely 72% fail

    Loses graph optimization benefits

  2. Set experimental_relax_shapes=True 78% fail

    May produce wrong results
