InPlaceAccumulatorV2 - 1 (com.microsoft)#
This version of the operator has been available since version 1 of domain com.microsoft.
In-place accumulator for tensors. Differs from older op by adding overwrite_flag for reset, and making output buffer as optional. Set the overwrite_flag to false for gradient accumulation and to True for overwriting the accumulation buffer during gradient computation (equivalent to reset grad + train step)
Between 2 and 3 inputs.
accumulation_buffer (heterogeneous) - T: historical result of accumulator
value (heterogeneous) - T_GRAD: the value that will be added to the accumulator
overwrite_flag (optional, heterogeneous) - T_BOOL: Indicates if tensor should be overwritten. Default is accumulation
Between 1 and 2 outputs.
updated_flag (heterogeneous) - T_BOOL: Whether the update was completed
accumulation_buffer_out (optional, heterogeneous) - T: updated result of accumulator
