Root Cause

Variable used before initialization (TF1 style code in TF2).

generic

Workarounds

  1. 90% success Migrate to TF2 eager execution and Keras layers
  2. 88% success Use tf.Variable with initial_value instead of tf.compat.v1.get_variable

Dead Ends

Common approaches that don't work:

  1. Add tf.compat.v1.global_variables_initializer() everywhere 75% fail

    Band-aid for TF1 code, not idiomatic TF2

  2. Disable eager execution globally 88% fail

    Breaks TF2 APIs and Keras
