How to Print the Value of a Tensor Object in TensorFlow

When working with Tensor objects in TensorFlow, it's common to encounter the need to print their values. However, simply printing a Tensor object will only display its metadata, not its actual value.

Solution: Using Session.run() or Tensor.eval()

The most straightforward way to obtain the value of a Tensor object is to use the Session.run() method or the Tensor.eval() function. This evaluates the Tensor within a session, executing any necessary operations and returning its calculated value.

In an interactive session, you can use:

with tf.Session() as sess:
    print(product.eval())

Alternatively, you can explicitly create a session and run the Tensor:

sess = tf.Session()
value = sess.run(product)
print(value)

Alternative: Using tf.print() Operator

While not a direct way to print the value of a Tensor, the tf.print() operator can be used to display the value during execution. However, it requires manually running the operation, either using Session.run() or as a control dependency.

Deferred Execution in TensorFlow

It's important to note that in TensorFlow, operations are not executed until explicitly requested. This allows for efficient scheduling and optimization of operations within a session. Therefore, it's necessary to use a session to evaluate Tensors and obtain their values.
