How statistics are calculated
We count how many offers each candidate received and for what salary. For example, if a Data Science developer with TensorFlow with a salary of $4,500 received 10 offers, then we would count him 10 times. If there were no offers, then he would not get into the statistics either.
The graph column is the total number of offers. This is not the number of vacancies, but an indicator of the level of demand. The more offers there are, the more companies try to hire such a specialist. 5k+ includes candidates with salaries >= $5,000 and < $5,500.
Median Salary Expectation – the weighted average of the market offer in the selected specialization, that is, the most frequent job offers for the selected specialization received by candidates. We do not count accepted or rejected offers.

Quick Facts about TensorFlow
Unraveling TensorFlow's Time Capsule
Picture this: it's November 2015, and Google Brain bestows upon the world a shiny new plaything named TensorFlow. Why? To transform brainwaves into code! It made such a smashing debut that it evolved into the go-to toolkit for machine learning mavericks hungry for neural network nirvana. Dim the lights for a TensorFlow origin story!
TensorFlow's Talent For Transformation
Now, what's a show without a little magic? TensorFlow's ability to perform automatic differentiation is like pulling a rabbit from a hat—a core trick for optimizing the heck out of neural networks. It's the computational conjuring that powers machine learning, and let's be real, who doesn't love a good magic trick? Abracadabra!
Version Victory Lap
Hold onto your keyboards, folks! TensorFlow has had quite the makeover since its debut. Version 2.0 hit the runway in September 2019, strutting out with a user-friendly interface, eager execution by default, and a tighter integration with Keras—a modeling closet filled with the trendiest high-level neural network chic. The code snippet below whispers sweet nothings to TensorFlow 2.0, seducing it into performing a simple operation:
import tensorflow as tf
# TensorFlow's eager execution is on by default in version 2.0
# No need to wait for your Session, let’s multiply straight away!
a = tf.constant([[1, 2], [3, 4]])
b = tf.constant([[5, 6], [7, 8]])
c = tf.matmul(a, b)
print("Just doing some casual matrix multiplication here: \n", c)

Python
Picture a world where you could converse with your computer as casually as you chat with your buddy about last night's game. Python is that buddy for TensorFlow development—it's the cool kid on the block. With Python's ease of use, you can whip up machine learning models faster than you can say 'NumPy' three times fast. TensorFlow and Python go together like peanut butter and jelly, a match made in coding heaven.
Keras
Imagine Keras as the friendly neighborhood superhero of TensorFlow's sprawling metropolis. Simple to use, yet incredibly powerful—it's the Robin to TensorFlow's Batman, making machine learning as approachable as microwaving popcorn. Use Keras when you need to get a model up and running before your coffee even gets cold.
NumPy
NumPy is like the Swiss Army knife in your TensorFlow toolkit. Crunching numbers with the grace of a ballet dancer and the precision of a laser beam, this library is all about handling those pesky vectors and matrices that machine learning feasts on. Forget about the manual labor; let NumPy do the heavy lifting!
TensorBoard
Ever wish you had a magical looking glass to peer into the black box of your neural network? Enter TensorBoard! It’s like the reality show of TensorFlow; you get a front-row seat to watch your models learn, stumble, and get back up. Debugging and visualizing have never been this entertaining—or educational.
SciPy
If TensorFlow is the playground, SciPy is the sophisticated older cousin who's seen it all. Rooted in scientific computing, SciPy brings a wealth of algorithms to the table, providing that extra brainpower needed for tasks that NumPy just can't handle on its own. It's the cherry on top of your computational sundae.
