# tf_quant_finance.utils.common_shape
View source
Returns common shape for a sequence of Tensors.
```python
tf_quant_finance.utils.common_shape(
*, name=None, *args
)
```
The common shape is the smallest-rank shape to which all tensors are
broadcastable.
#### Example
```python
import tensorflow as tf
import tf_quant_finance as tff
args = [tf.ones([1, 2], dtype=tf.float64), tf.constant([[True], [False]])]
tff.utils.common_shape(*args)
# Expected: [2, 2]
```
#### Args:
* `*args`: A sequence of `Tensor`s of compatible shapes and any `dtype`s.
* `name`: Python string. The name to give to the ops created by this function.
Default value: `None` which maps to the default name
`broadcast_tensor_shapes`.
#### Returns:
A common shape for the input `Tensor`s, which an instance of TensorShape,
if the input shapes are fully defined, or a `Tensor` for dynamically shaped
inputs.
#### Raises:
* `ValueError`: If inputs are of incompatible shapes.
