**Summary**

LayerNormalizationGrad

**Attributes**

* **axis**:
  The first normalization dimension: normalization will be performed
  along dimensions axis : rank(inputs). Default value is ``?``.

**Inputs**

* **Y_grad** (heterogeneous) - **V**:
  The gradient tensor from output.
* **X** (heterogeneous) - **T**:
  Input data tensor from the forward path
* **scale** (heterogeneous) - **V**:
  Scale tensor.
* **mean** (heterogeneous) - **U**:
  mean of X.
* **inv_std_dev** (heterogeneous) - **U**:
  inverse std deviation of X.

**Outputs**

* **X_grad** (heterogeneous) - **T**:
  Gradient of the input.
* **scale_grad** (heterogeneous) - **V**:
  Gradient of the scale.
* **bias_grad** (heterogeneous) - **V**:
  Gradient of the bias.
