示例1: _BiasAddGrad
# 需要導入模塊: from tensorflow.python.ops import gen_nn_ops [as 別名]
# 或者: from tensorflow.python.ops.gen_nn_ops import bias_add_grad [as 別名]
def _BiasAddGrad(op, received_grad):
"""Return the gradients for the 2 inputs of bias_op.
The first input of unused_bias_op is the tensor t, and its gradient is
just the gradient the unused_bias_op received.
The second input of unused_bias_op is the bias vector which has one fewer
dimension than "received_grad" (the batch dimension.) Its gradient is the
received gradient Summed on the batch dimension, which is the first dimension.
Args:
op: The BiasOp for which we need to generate gradients.
received_grad: Tensor. The gradients passed to the BiasOp.
Returns:
Two tensors, the first one for the "tensor" input of the BiasOp,
the second one for the "bias" input of the BiasOp.
