[`tf.compat.v1.math.reduce_prod`](https://www.tensorflow.org/api_docs/python/tf/compat/v1/reduce_prod)

<br />

    tf.compat.v1.reduce_prod(
        input_tensor,
        axis=None,
        keepdims=None,
        name=None,
        reduction_indices=None,
        keep_dims=None
    )

> [!WARNING]
> **Deprecated:** SOME ARGUMENTS ARE DEPRECATED: `(keep_dims)`. They will be removed in a future version. Instructions for updating: keep_dims is deprecated, use keepdims instead

This is the reduction operation for the elementwise [`tf.math.multiply`](https://www.tensorflow.org/versions/r2.13/api_docs/python/tf/math/multiply) op.

Reduces `input_tensor` along the dimensions given in `axis`.
Unless `keepdims` is true, the rank of the tensor is reduced by 1 for each
of the entries in `axis`, which must be unique. If `keepdims` is true, the
reduced dimensions are retained with length 1.

If `axis` is None, all dimensions are reduced, and a
tensor with a single element is returned.

| ## For example ||
|---|---|
| <br /> >>> x = tf.constant([[1., 2.], [3., 4.]]) >>> tf.math.reduce_prod(x) <tf.Tensor: shape=(), dtype=float32, numpy=24.> >>> tf.math.reduce_prod(x, 0) <tf.Tensor: shape=(2,), dtype=float32, numpy=array([3., 8.], dtype=float32)> >>> tf.math.reduce_prod(x, 1) <tf.Tensor: shape=(2,), dtype=float32, numpy=array([2., 12.], dtype=float32)> <br /> ||

| ## Args ||
|---|---|
| `input_tensor` | The tensor to reduce. Should have numeric type. |
| `axis` | The dimensions to reduce. If `None` (the default), reduces all dimensions. Must be in the range `[-rank(input_tensor), rank(input_tensor))`. |
| `keepdims` | If true, retains reduced dimensions with length 1. |
| `name` | A name for the operation (optional). |
| `reduction_indices` | The old (deprecated) name for axis. |
| `keep_dims` | Deprecated alias for `keepdims`. |
