Sum the weights of false positives.

    tf.compat.v1.metrics.false_positives(
        labels,
        predictions,
        weights=None,
        metrics_collections=None,
        updates_collections=None,
        name=None
    )

If `weights` is `None`, weights default to 1. Use weights of 0 to mask values.

| ## Args ||
|---|---|
| `labels` | The ground truth values, a `Tensor` whose dimensions must match `predictions`. Will be cast to `bool`. |
| `predictions` | The predicted values, a `Tensor` of arbitrary dimensions. Will be cast to `bool`. |
| `weights` | Optional `Tensor` whose rank is either 0, or the same rank as `labels`, and must be broadcastable to `labels` (i.e., all dimensions must be either `1`, or the same as the corresponding `labels` dimension). |
| `metrics_collections` | An optional list of collections that the metric value variable should be added to. |
| `updates_collections` | An optional list of collections that the metric update ops should be added to. |
| `name` | An optional variable_scope name. |

<br />

<br />

<br />

<br />

| ## Returns ||
|---|---|
| `value_tensor` | A `Tensor` representing the current value of the metric. |
| `update_op` | An operation that accumulates the error from a batch of data. |

<br />

<br />

<br />

<br />

| ## Raises ||
|---|---|
| `ValueError` | If `predictions` and `labels` have mismatched shapes, or if `weights` is not `None` and its shape doesn't match `predictions`, or if either `metrics_collections` or `updates_collections` are not a list or tuple. |
| `RuntimeError` | If eager execution is enabled. |
