    tf.compat.v1.argmax(
        input,
        axis=None,
        name=None,

> [!WARNING]
> **Deprecated:** SOME ARGUMENTS ARE DEPRECATED: `(dimension)`. They will be removed in a future version. Instructions for updating: Use the `axis` argument instead

Note that in case of ties the identity of the return value is not guaranteed.

| ## Usage ||
|---|---|
| <br /> import tensorflow as tf a = [1, 10, 26.9, 2.8, 166.32, 62.3] b = tf.math.argmax(input = a) c = tf.keras.backend.eval(b) # c = 4 # here a[4] = 166.32 which is the largest element of a across axis 0 <br /> ||

| ## Args ||
|---|---|
| `input` | A `Tensor`. Must be one of the following types: `float32`, `float64`, `int32`, `uint8`, `int16`, `int8`, `int64`, `bfloat16`, `uint16`, `half`, `uint32`, `uint64`, `qint8`, `quint8`, `qint32`, `qint16`, `quint16`, `bool`. |
| `axis` | A `Tensor`. Must be one of the following types: `int16`, `int32`, `int64`. int16, int32 or int64, must be in the range `[-rank(input), rank(input))`. Describes which axis of the input Tensor to reduce across. For vectors, use axis = 0. |
| `output_type` | An optional [`tf.DType`](https://www.tensorflow.org/versions/r2.13/api_docs/python/tf/dtypes/DType) from: `tf.int16, tf.uint16, tf.int32, tf.int64`. Defaults to [`tf.int64`](https://www.tensorflow.org/versions/r2.13/api_docs/python/tf#int64). |
| `name` | A name for the operation (optional). |

<br />

| ## Returns ||
|---|---|
| A `Tensor` of type `output_type`. ||
