TensorFlow Basics

Install TensorFlow
pip install tensorflow

Import
import tensorflow as tf
print(tf.__version__)

Check GPU availability
print(tf.config.list_physical_devices("GPU"))

Create tensor
tensor = tf.constant([1, 2, 3, 4])

Create tensor with shape
matrix = tf.constant([[1, 2], [3, 4]])

Zeros and ones
zeros = tf.zeros([3, 3])
ones = tf.ones([2, 2])

Random values
random = tf.random.normal([3, 3])

Tensor properties
print(tensor.shape)
print(tensor.dtype)

Arithmetic operations
a = tf.constant([1, 2, 3])
b = tf.constant([4, 5, 6])

add = a + b
sub = a - b
mul = a * b
div = a / b

Matrix multiplication
matmul = tf.matmul(matrix1, matrix2)

Reshape tensor
reshaped = tf.reshape(tensor, [2, 2])

Create variable
var = tf.Variable([1.0, 2.0, 3.0])

Assign new value
var.assign([4.0, 5.0, 6.0])

Add to variable
var.assign_add([1.0, 1.0, 1.0])

Multiply variable
var.assign_sub([0.5, 0.5, 0.5)
