TPUExecuteAndUpdateVariables

public final class TPUExecuteAndUpdateVariables

Op that executes a program with optional in-place variable updates.

It (optionally) reads device variables, loads and executes a TPU program on a TPU device, and then (optionally) in-place updates variables using the program outputs, as specified in attributes device_var_reads_indices (program input indices from directly reading variables) and device_var_updates_indices (program output indices used to update variables, -1 means no-update/read-only). Such program outputs are consumed by these variables will not appear in the op output. For the internal use of the distributed TPU compiler.
