TensorFlow Developer

TensorFlow is a machine learning and artificial intelligence software library that is free and open-source. It can be used for various applications, but it focuses on deep neural network training and inference. The Google Brain team created TensorFlow for internal Google use in research and production. It’s compatible with various programming languages, including Python, Javascript, C++, and Java. Many Google products and teams use TensorFlow, including Search, Gmail, Translate, Maps, Android, Photos, Speech, YouTube, and Play.

TensorFlow is a set of procedures that allow both novices and experts to develop machine learning models in various languages using intuitive, high-level APIs. Models can be deployed on various platforms, including servers, the cloud, mobile, and edge devices, browsers, and various other JavaScript platforms. This makes the transition from model design to training and deployment easier for developers.

The TensorFlow Developer certificate can also be obtained via the internet. The TensorFlow Developer Certification is required to demonstrate your ability to utilize TensorFlow effectively.

TensorFlow dict to Tensor

TensorFlow is a Google-developed open-source Python toolkit for developing Machine Learning models and deep learning neural networks. To convert a value to a Tensor, use the convert to tensor() function.


tensorflow.convert_to_tensor( value, dtype, dtype_hint, name )


  • value: It’s the number that must be transformed into a Tensor.
  • dtype(optional): It specifies the output Tensor’s type.
  • dtype_hint(optional): When dtype is None, it is used. While converting to a tensor, a caller may not have a dtype in mind. As a result, you can utilize dtype hint as a soft preference. This parameter has no effect if the conversion to dtype hint is impossible.
  • name(optional): It specifies the operation’s name.

Model Parallelism TensorFlow

The technique of spreading a model across several devices or nodes (such as GPU-equipped instances) and constructing an efficient pipeline to train the model across these devices to maximize GPU utilization is known as model parallelism. Model parallelism should be used when training on a single GPU is not practicable due to memory constraints. This method divides the model into many GPUs and runs each portion on a separate accelerator. Huge models can be divided up and made to fit in memory. In the past, putting this strategy into practice was quite difficult. Fair model splitting, accurate GPU assignment, and efficient execution are difficult to achieve.

TensorFlow reshape

Tensors can be reshaped using Tensorflow’s built-in reshape() function to meet input requirements and preserve consistency. Using tf.reshape(), we can change the shape and rank of a tensor without affecting the constituent elements or their order of appearance. Regardless of the size and rank of the original tensor, this makes the function incredibly dynamic and quick to implement. This reshapes capability allows Data Scientists to train AI neural networks in various ways, allowing them to perform complex search operations, audio/video file matching, image processing, and natural language classification properly and quickly. It also enables the creation of a wide range of new data models to develop robust and dependable AI solutions.


tensorflow.reshape(tensor, shape, name=None)


  • tensor: the to-be-reshaped tensor
  • shape: the output tensor’s shape
  • name: name of the operation (optional)

TensorFlow Variable

The suggested way to describe the shared, permanent state that your program manipulates is with a TensorFlow variable. The tf.Variable class is used to create and track variables. A tf.Variable is a tensor that can alter its value by conducting operations on it. This tensor’s values can be read and modified using specific operators. Tf.Variable is used by higher-level libraries like tf.keras to hold model parameters. Provide an initial value to create a variable. The initialization value’s dtype will be the same as the tf.Variable.


tf.Variable(initial_value=None, trainable=None, validate_shape=True, caching_device=None, name=None, variable_def=None, dtype=None, import_scope=None, constraint=None,synchronization=tf.VariableSynchronization.AUTO, aggregation=tf.compat.v1.VariableAggregation.NONE, shape=None)


  • initial_value: as the default None. The Variable’s initial value is a Tensor or a Python object that can be converted to a Tensor.
  • trainable: None is the default value. If True, GradientTapes will monitor the use of this variable.
  • validate_shape: True by default. If False, the variable can be started with an unknown shape value. If True, which is the default, the shape of the initial value must be known.
  • name: as the default None. The name of the variable is optional. ‘Variable’ is the default value, and it is automatically uniquified.
  • variable_def: None is the default value.
  •  dtype: None is the default value. The initial value will be transformed to the specified type if the initial value is set. If None is specified, either the datatype (if the initial value is a Tensor) or convert to tensor will be used to determine the datatype.
  •  shape: None is the default value. If None, the initial value’s shape will be utilized. If a shape is supplied, that form will be used to assign the variable.


TensorFlow Einsum

Tensors can be defined in Einsum by specifying their element-wise processing. Equation, a shorthand form based on Einstein’s summation, is used to define this computation.


tf.einsum (equation, tensors)


  • equation: It’s the initial input tensor element, and it’s a string that describes the contraction in the same manner as numpy.einsum.
  • . . . tensors: It’s a second input tensor element in which the input(s) are utilized to contract (each a Tensor), and the shapes should match the equation.


  • It does not support tensors with two inputs.
  • For every given input tensor, it does not accept duplicate axes. 
  • The… notation isn’t recognized.

TensorFlow Split

To split a tf.tensors into sub tensors, use the tf.split() function.


tf.split (x, numOrSizeSplits, axis?)


  • x: The tensor to split as input.
  • numOrSizeSplits: It can either be a number indicating the number of splits or an array containing sizes for each output tensor.
  • axis: It is a dimension’s axis along which to split.

TensorFlow Gelu

The Gaussian Error Linear Unit, or GELU, is a function that activates a function. The Gaussian error linear unit (GELU) calculates x * P(X <= x), where P(X) ~ N(0, 1). In contrast to ReLU, the (GELU) nonlinearity weights inputs based on their value rather than their sign.

TensorFlow lstmcell

For the LSTM Cell class, the layers.lstmCell() function is utilized. It’s not the same as the RNN subclass.



Parameters: (The args object in the function has the following parameters.)

  • recurrentactivation: It is used to make recurring steps active.
  • unitForgetBias: It’s a boolean used to enable the forget gate during initialization.

  • implementation: It’s either an integer or a string that specifies the implementation modes. MODE 1 organizes activities into a higher number of smaller dot products and additions. MODE 2 is used to consolidate the activities into fewer, larger ones.

  • units: It’s a number, whether an integer or the output space’s dimensions.

  • activation: It is used to perform the function.

  • useBias: The use of a bias vector by the layer is a boolean.

  • kernelInitializer: It’s used to turn the inputs into a linear format.

  • recurrentInitializer: It translates the recurrent state into a linear form.

  • biasInitializer: It’s what the bias vector is made of.

  • kernelRegularizer: It’s a string used by the Kernel Weights Matrix Regularizer function.

  • recurrentRegularizer: It’s a string that gets applied to the recurrent kernel weights matrix by the Regularizer function.

  • biasRegularizer: It’s a string that’s used to apply the Regularizer function to the bias vector.

  • kernelConstraint: It’s a string used by the kernel weights matrix’s Constraint function.

  • recurrentConstraint: It’s a string that the Constraint function uses to constrain the recurrentKernel weights matrix.

  • iasConstraint: It’s a string that’s used to apply the Constraint function to the bias vector.

  • dropout: It’s a number that ranges from 0 to 1. A fraction of the units should be dropped for the linear transformation of the inputs.

  • recurrentDropout: It’s a number that ranges from 0 to 1. The fraction of units decreases when the recurrent state is transformed linearly.

  • inputShape: It’s a number utilized to make an input layer that goes before this one.

  • batchInputShape: It’s a number used to make an input layer that’ll be placed before this one.

  • batchSize: It’s a number that’s utilized to make the batchInputShape.

  • dtype: Only input layers are affected by this option.

  • name: It’s a string used by the layer.

  • trainable: It’s a boolean value that indicates whether or not the weights of this layer can be updated by fit.

  • weights: It’s the layer’s initial weight values.

  • inputDType: It’s used to support legacy systems. It can’t be used for new codes.

TensorFlow Transpose

TensorFlow includes a function called tf.transpose(). The input tensor is transposed using this function.


tf.transpose(input_tensor, perm, conjugate)


  • input_tensor: The tensor is to be transposed, as the name implies.
  • Type: Tensor
  • perm: This option defines the permutation used to transpose the input_tensor.
  • Type: Vector
  • conjugate: If the input_tensor is type complex, this argument is set to True.
  • Type: Boolean

Use Pip:

!pip show tensorflow


TensorFlow Conv2D

The Conv2D class in Tensorflow and Keras allows us to apply the convolution function on two-dimensional inputs. Keras Conv2D is a two-dimensional convolution layer that generates a tensor of outputs by winding a convolution kernel with the layer’s input. A bias vector is constructed and appended to the outputs if the used bias is True. Finally, if activation is None, the outputs are activated as well.

TensorFlow decode image

TensorFlow includes the tf.io and tf.image modules for reading and processing images. This function determines whether an image is a BMP, GIF, JPEG, or PNG. It also uses the appropriate procedure to convert the input bytes string into a Tensor of type dtype. It has decode bmp, decode gif, decode jpeg, and decode png functions.










TensorFlow Equal

The tensor of Boolean values for the two provided tensor values is returned by the tf.equal() function, which returns true if the first tensor value is equal to the second tensor value and false otherwise. Broadcasting is supported.



tf.equal(a, b)




  • a: The first tensor in the input.

  • b: The tensor for the second input. Its values should be of the same data type as tensor “a.”
