TensorFlow is a Python-based toolkit for developing machine learning applications. It is a low-level toolset for performing difficult mathematical operations. It provides users with the opportunity to customize experiential learning architectures. It also makes it easier for users to deal with them and turn them into functioning software.

Whether you are a candidate actively looking for TensorFlow developer jobs or a recruiter looking for TensorFlow developers, the following list of TensorFlow interview questions will be of great use for you.

TensorFlow interview questions and answers

1.

What is a Tensor?


This is a basic, yet important TensorFlow interview question. The Tensor is a generalization of n-dimensional array vectors or matrices used in computer programming. It is a collection of numbers that represent a large amount of data. There are a few alternative n-dimensional array libraries available on the internet, such as Numpy, but TensorFlow stands out. It includes methods for generating Tensor functions and computing derivatives automatically.

2.

What is a TensorBoard?


TensorBoard is a collection of visual tools for inspecting and comprehending TensorFlow runs and graphs. It is a simple solution to TensorFlow provided by the creators that allow us to see the graphs. It plots quantitative measures around the graph while also allowing other data such as photos to pass through it. TensorBoard presently supports five types of visualizations: scalars, pictures, audio, histograms, and graphs. It enhances graph accuracy and flow.

3.

What is TensorFlow serving?


You will often come across this TensorFlow interview question. TensorFlow Serving is intended for use in production settings. It is a high-performance, flexible serving system for machine learning models. TensorFlow Serving allows for the rapid deployment of new algorithms and experiments while maintaining the same server architecture and APIs. TensorFlow Serving supports TensorFlow models right out of the box. It is also easily extensible to support various sorts of models and data as needed.

4.

What are the types of tensors?


This is a popular tensorflow coding interview question. There are four types of Tensors used to create machine learning models:

  • Tensor Constant: Constant Tensors, as the name implies, are employed as constants. They build a node that accepts a value but does not alter it. tf.constant can be used to construct a constant. value, dtype=None, shape=None, name='Const', verify shape=False) It agrees with the five arguments.
  • Tensor Variable: Variable Tensors are the nodes that output their current value. It means that they can retain their value across several graph runs.
  • Placeholder Tensor: Placeholders Variables are not as important as tensors. These are used to assign data in the future. Placeholders are nodes whose values are fed during execution. Assume we have network inputs that are dependent on some external data. Also, if we do not want our graph to be dependent on any real values while creating it, Placeholders are a handy datatype. We can even create a graph in the absence of data. As a result, placeholders do not need an initial value. They simply require a datatype (such as float32) and a tensor structure, so the graph knows what to compute even if no values are saved.
  • Sparse Tensor: A sparse tensor is a dataset in which the majority of the entries are zero. A big diagonal matrix is an example. (which has a large number of zeros) It doesn't save the entire tensor object's values; instead, it saves the non-zero values and their coordinates.

5.

How can you load data into TensorFlow?


The initial step in training a machine learning algorithm is to load the data into TensorFlow. There are two methods for loading the data:

Load information into memory

It is the most straightforward way. The data is put into memory in the form of a single array. Python code that is unrelated to TensorFlow can be written.

Data pipeline based on TensorFlow

TensorFlow includes APIs that make it simple to import data, perform operations, and feed the machine learning algorithm. When there is a huge dataset, this strategy is typically employed.

6.

What are loaders?


You will often come across this TensorFlow interview question. The loader is capable of loading, unloading, and accessing a new sort of servable machine learning model. These loaders are used on the backend to add algorithms and data. The load() function is used to load the model from the saved model.

7.

What is Deep Speech?


Deep Speech is a free and open-source engine for converting speech to text. It employs a model that has been trained using machine learning techniques. It is based on a research paper published by Baidu called Deep Speech. It takes advantage of Google's TensorFlow to facilitate implementation.

8.

How is the Python API used in TensorFlow?


You will often come across this tensorflow interview question. When it comes to TensorFlow and its development, Python is the key language. It was the first and most well-known language supported by TensorFlow, and it still supports the majority of its capabilities. TensorFlow's functionality appears to have been defined in Python first and then ported to C++. The Python programming language is used to power the majority of TensorFlow's APIs. They provide users with low-level options, such as tf.manual or tf.nn.relu, which are used to design Neural Network Architecture. These APIs are also used to create deep neural networks with various levels of abstraction.

9.

Mention the APIs used outside the TensorFlow.


TFLearn: TFLearn provides a high-level API that enables neural network creation and training quickly and simply. TensorFlow is fully compatible with this API. Its API is denoted as tf.contrib.learn.

TensorLayer: TensorLayer is a deep learning and reinforcement learning library built on TensorFlow. It is intended for scientists and engineers. It offers a large array of programmable neural layers/functions, which are essential for developing real-world AI applications.

PrettyTensor: Pretty Tensor provides a high-level TensorFlow building API. It provides thin wrappers for Tensors, allowing you to easily design multi-layer neural networks. Pretty Tensor is a collection of objects that behave like Tensors. It also includes a chainable object syntax for quickly defining neural networks and other layered architectures in TensorFlow.

Sonnet: Sonnet is a TensorFlow-based framework for building complicated neural networks. It is a component of Google's DeepMind project, which employs a modular approach.

10.

What is an embedding projector?


You will often come across this tensorflow interview question. The Embedding Projector can display high-dimensional data. For example, after input data has been embedded in a high-dimensional space by model, it can be viewed. The model checkpoint file is read by the embedding projector. It can be customized with other metadata such as a vocabulary file or sprite pictures.

Wrapping up

The above list of TensorFlow interview questions will be an important part of your TensorFlow interview preparation. These TensorFlow interview questions will assist you in solving similar queries or generating new ones. A TensorFlow interview, on the other hand, would not consist solely of these technical TensorFlow interview questions. A TensorFlow interview may also include questions regarding a person's social and life abilities. This allows the recruiter to determine whether the individual can persevere in difficult situations while also assisting their coworkers. As a recruiter, finding someone who gets along with the rest of the team is critical.
