tf.compat.v1.keras.backend.set_floatx

tf.keras.backend.set_floatx(
    value
)

Note: It is not recommended to set this to float16 for training, as this will likely cause numeric stability issues. Instead, mixed precision, which is using a mix of float16 and float32, can be used by calling tf.keras.mixed_precision.experimental.set_policy('mixed_float16'). See the mixed precision guide for details.

Arguments
value	String; 'float16', 'float32', or 'float64'.

Example:

tf.keras.backend.floatx() 'float32' tf.keras.backend.set_floatx('float64') tf.keras.backend.floatx() 'float64' tf.keras.backend.set_floatx('float32')

Raises
ValueError	In case of invalid value.
