tf.train.experimental.disable_mixed_precision_graph_rewrite

View source

Disables the mixed precision graph rewrite.

Aliases:

  • tf.compat.v2.train.experimental.disable_mixed_precision_graph_rewrite
tf.train.experimental.disable_mixed_precision_graph_rewrite()

After this is called, the mixed precision graph rewrite will no longer run for tf.functions, and so float32 operations will no longer be converted to float16.

This does not undo the effects of loss scaling. Any optimizers wrapped with a LossScaleOptimizer will continue to do loss scaling, although this loss scaling will no longer be useful, as the graph rewrite no longer converts tf.functions to use float16.

This function is useful for unit testing. A unit test can test using the mixed precision graph rewrite, then disable it so future unit tests continue using float32.
