tf.experimental.dtensor.default_mesh

Sets the default DTensor device mesh to use for enclosed functions.

This function returns a scope. All the ops and tf.functions in this scope will default to this DTensor mesh if a mesh cannot be inferred from any of the inputs This is useful for wrapping any tf.function that doesn't take a DTensor as input but would like to produce DTensor as result. The scope will also make sure all small constants are replicated as DTensors.

mesh A Mesh instance to extract a default mesh from.

A context in which all ops and tf.functions will run on the given mesh.
