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

<br />

    tf.raw_ops.ListDiff(
        x,
        y,
        out_idx=https://www.tensorflow.org/versions/r2.13/api_docs/python/tf/dtypes#int32,
        name=None
    )

Given a list `x` and a list `y`, this operation returns a list `out` that
represents all values that are in `x` but not in `y`. The returned list `out`
is sorted in the same order that the numbers appear in `x` (duplicates are
preserved). This operation also returns a list `idx` that represents the
position of each `out` element in `x`. In other words:

`out[i] = x[idx[i]] for i in [0, 1, ..., len(out) - 1]`

For example, given this input:

    x = [1, 2, 3, 4, 5, 6]
    y = [1, 3, 5]

This operation would return:

    out ==> [2, 4, 6]
    idx ==> [1, 3, 5]

| ## Args ||
|---|---|
| `x` | A `Tensor`. 1-D. Values to keep. |
| `y` | A `Tensor`. Must have the same type as `x`. 1-D. Values to remove. |
| `out_idx` | An optional [`tf.DType`](https://www.tensorflow.org/versions/r2.13/api_docs/python/tf/dtypes/DType) from: `tf.int32, tf.int64`. Defaults to [`tf.int32`](https://www.tensorflow.org/versions/r2.13/api_docs/python/tf#int32). |
| `name` | A name for the operation (optional). |

<br />

<br />

| ## Returns ||
|---|---|
| A tuple of `Tensor` objects (out, idx). ||
| `out` | A `Tensor`. Has the same type as `x`. |
| `idx` | A `Tensor` of type `out_idx`. |
