tf.compat.v1.enable_control_flow_v2

tf.enable_control_flow_v2()

control flow v2 (cfv2) is an improved version of control flow in TensorFlow with support for higher order derivatives. Enabling cfv2 will change the graph/function representation of control flow, e.g., tf.while_loop and tf.cond will generate functional While and If ops instead of low-level Switch, Merge etc. ops. Note: Importing and running graphs exported with old control flow will still be supported.

Calling tf.enable_control_flow_v2() lets you opt-in to this TensorFlow 2.0 feature.

Note: v2 control flow is always enabled inside of tf.function. Calling this function is not required.
