/TensorFlow 1.15


Use 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.
