# tf.split

Splits a tensor into sub tensors.

If `num_or_size_splits` is an integer, then `value` is split along dimension `axis` into `num_split` smaller tensors. This requires that `num_split` evenly divides `value.shape[axis]`.

If `num_or_size_splits` is a 1-D Tensor (or list), we call it `size_splits` and `value` is split into `len(size_splits)` elements. The shape of the `i`-th element has the same size as the `value` except along dimension `axis` where the size is `size_splits[i]`.

#### For example:

``````# 'value' is a tensor with shape [5, 30]
# Split 'value' into 3 tensors with sizes [4, 15, 11] along dimension 1
split0, split1, split2 = tf.split(value, [4, 15, 11], 1)
tf.shape(split0)  # [5, 4]
tf.shape(split1)  # [5, 15]
tf.shape(split2)  # [5, 11]
# Split 'value' into 3 tensors along dimension 1
split0, split1, split2 = tf.split(value, num_or_size_splits=3, axis=1)
tf.shape(split0)  # [5, 10]
``````

`value` The `Tensor` to split.
`num_or_size_splits` Either an integer indicating the number of splits along `axis` or a 1-D integer `Tensor` or Python list containing the sizes of each output tensor along `axis`. If a scalar, then it must evenly divide `value.shape[axis]`; otherwise the sum of sizes along the split axis must match that of the `value`.
`axis` An integer or scalar `int32` `Tensor`. The dimension along which to split. Must be in the range `[-rank(value), rank(value))`. Defaults to 0.
`num` Optional, used to specify the number of outputs when it cannot be inferred from the shape of `size_splits`.
`name` A name for the operation (optional).

if `num_or_size_splits` is a scalar returns `num_or_size_splits` `Tensor` objects; if `num_or_size_splits` is a 1-D Tensor returns `num_or_size_splits.get_shape[0]` `Tensor` objects resulting from splitting `value`.

`ValueError` If `num` is unspecified and cannot be inferred.
