Creating Tensors with Variables

In [2]:

import tensorflow as tf

In [6]:

startingArr = [10,6]
varTensor = tf.Variable(startingArr)
constTensor = tf.constant(startingArr)
varTensor, constTensor

Out [6]:

(<tf.Variable 'Variable:0' shape=(2,) dtype=int32, numpy=array([10,  6], dtype=int32)>,
 <tf.Tensor: shape=(2,), dtype=int32, numpy=array([10,  6], dtype=int32)>)

Changing A Variable Tensor

In [7]:

varTensor[0].assign(123)
varTensor

Out [7]:

<tf.Variable 'Variable:0' shape=(2,) dtype=int32, numpy=array([123,   6], dtype=int32)>

Changing A Constant Tensor

In [9]:

constTensor[0].assign(123)
constTensor
# shows error
# object has no attribute 'assign'
