Outputs deterministic pseudorandom values from a uniform distribution.
tf.random.stateless_uniform(
shape, seed, minval=0, maxval=None, dtype=tf.dtypes.float32, name=None
)
This is a stateless version of tf.random.uniform
: if run twice with the
same seeds, it will produce the same pseudorandom numbers. The output is
consistent across multiple runs on the same hardware (and between CPU
and GPU), but may change between versions of TensorFlow or on non-CPU/GPU
hardware.
The generated values follow a uniform distribution in the range
[minval, maxval)
. The lower bound minval
is included in the range, while
the upper bound maxval
is excluded.
For floats, the default range is [0, 1)
. For ints, at least maxval
must
be specified explicitly.
In the integer case, the random integers are slightly biased unless
maxval - minval
is an exact power of two. The bias is small for values of
maxval - minval
significantly smaller than the range of the output (either
2**32
or 2**64
).
For full full-range (i.e. inclusive of both max and min) random integers, pass
minval=None
and maxval=None
with an integer dtype
. For an integer dtype
either both minval
and maxval
must be None
or neither may be None
. For
example:
ints = tf.random.stateless_uniform(
[10], seed=(2, 3), minval=None, maxval=None, dtype=tf.int32)
Args | |
---|---|
shape
|
A 1-D integer Tensor or Python array. The shape of the output tensor. |
seed
|
A shape [2] integer Tensor of seeds to the random number generator. |
minval
|
A 0-D Tensor or Python value of type dtype . The lower bound on the
range of random values to generate. Pass None for full-range integers.
Defaults to 0.
|
maxval
|
A 0-D Tensor or Python value of type dtype . The upper bound on the
range of random values to generate. Defaults to 1 if dtype is floating
point. Pass None for full-range integers.
|
dtype
|
The type of the output: float16 , float32 , float64 , int32 , or
int64 . For unbounded uniform ints (minval , maxval both None ),
uint32 and uint64 may be used.
|
name
|
A name for the operation (optional). |
Returns | |
---|---|
A tensor of the specified shape filled with random uniform values. |
Raises | |
---|---|
ValueError
|
If dtype is integral and only one of minval or maxval is
specified.
