Numba really is great. Here is my first experience with it: I have some code that I estimated would take up to half a year to run. With some minor changes to the code for compatibility with Numba, the run time for the same conditions was up to 1.5 hours. This was a game-changer for me as I needed to run this script many times. One of my colleagues also implemented it into his machine learning code and managed to obtain some significant speed bumps.

[@tronali5703]

One thing to note is that Numba really optimizes nested loops. If you say have to call a function a 100 or million times, better to have an outerloop instead that iterates within the function. With parallel turned on, you can see a 1000x increase.

[@JackofSome]

This actually makes a lot of sense. Thanks for the comment!

[@chriskeo392]

This is crazy! Awesome

[@AlexanderHyll]

Its one of the only ways to run the notoriously slow nested loops in Python (whenever it can’t be vectorized). We had a simulation to run that went from 81 days pure python to 2h (~1000x).

[@joshuatyler4657]

I implemented it in my code, and it took around an hour worth of computation and put it down to 30 seconds. Amazing stuff.

[@JackofSome]

Nice nice!

[@joshuatyler4657]

@@JackofSome One funny thing that I found is that you can’t create numpy.linespace or numpy.arrange arrays with anything besides integers. I had to create an integer array, then divide it by 2 to make it a float32, and then populate it with a for loop to get the actual array I wanted. Also, numpy.zero arrays have to be initialized outside of the function and passed as an argument instead of being initialized in the array. But the extra work is worth the speed up.

I cannot thank you enough for this video. I made a simulation of Gray Scott's Reaction diffusion in python, but it was painstakingly slow. After using numba, it now runs quite fast. Earlier it took nearly about 1 hour to render just 100 frames at a mere 400x400 resolution, now it renders 100 frames in 45 seconds, in 1280x720 resolution. Thank you very much for this video.

python doesn't need to be faster, it designed to be simple not efficient. there are plenty other programming languages that designed to be efficient like C, C++ that has proved themself. sure they are hard to learn but trying to get python faster is just like reinvented the wheel, learning C++ from scratch in my opinion is much more beneficial in long term than trying to make python faster because essentially you are learning the same things but you won't get far with python.

11:45 - try this: np.zeros_like(input_list, dtype = np.int64, order='C') My experience with numba - it works great, but types have to be very precisely defined for every single object. Otherwise nopython will fail, and where numba sucks is generating traceback messages - in the case of complex functions it will take forever to debug. So type whatever you can - it is not a 'Pythonic' way of thinking and writing, but in this particular case it is necessary. Anyway, great introduction!

I don't know why I need this. I'm still a High School student doing python for fun. But imma keep this tucked away in my mind. I have a feeling I'll need it soon enough.

[@CrazyFanaticMan]

When your'e working on projects that needs the program to do things fast, you want C like performance because low level languages like C/C++ are about as fast as you can get. Python is not a low level language. It's a high level dynamically typed language. This means it's pretty slow. So even though it's pretty fast to write a python program because it's basically the same as writing in English, you're giving up the actual execution speed (performance) in order to keep that fast typing speed (developer performance). Numba solves this problem by keeping the Python typing that we all love and getting the C like performance that is needed for projects where speed is very important.

[@eskees9498]

@@CrazyFanaticMan so I'm also in high-school just doing python for fun. Is number useful for smaller projects or only for large projects. My biggest code is only about 80 lines of code, but it uses my Webcam to track hands. Would it be worth it to implement numba for this low amount of code?

[@CrazyFanaticMan]

@@eskees9498 It doesn't matter how many lines of code you have, whether it's 80 lines or a billion lines. What matters is the problem you are trying to solve. If for example you say "I want my webcam to not only accurately detect the location of my hands but I also want my webcam to track my hands if I move them really fast". I would imagine a webcam tracking hands that are moving really fast would require very fast performance speed in order to keep up. So in this case, numba may help you a lot. It all really depends on what you want and what your expectations are. The size of your program does not matter, numba can you help you whether you're program is big or small

4:06, so why can't you copy and paste this cached code into a new function, so it executes fast even on first run?

[@CoolDude911]

10:10 Why are numpy arrays slow to dynamically allocate? -> The basic answer is that it is a C++ vector underneath and that vector which can be given extra capacity to append elements but at a certain point it will have to ask the operating system for more contiguous memory and has to be reallocated (this is very slow). The solution is to assign the numpy array a certain length beforehand with the np.empty() function. Python is designed to be fast to allocate an object of any amount of memory and a uses a linked list for its List type. This does have a cost in terms of defragmentation and garbage collection and it is slower to iterate through a linked list as well. Thank you for this informative video.

[@JackofSome]

Python's lists are not linked lists, they are Implemented somewhat similar to vectors. They also have O(1) lookup, something you can't have with a linked list. This is a pretty common misconception I wonder where it comes from. Maybe a really old version used to have linked lists? Here's a link in the python docs talking about the basic implementation docs.python.org/3/faq/design.html#how-are-lists-implemented-in-cpython

[@CoolDude911]

@@JackofSome Oh cool, that's interesting. I assumed that because I found it faster to append a list than a numpy array. Maybe the numpy array is using a vector without a smart way of having extra capacity so it has to be reallocated all the time. I assume that a list in python has to contain pointers to a generic memory buffer objects so I guess the is linking going on there, as it has to allow fast generic memory allocation. It's funny how the inference time and allocation is measured but that does not take into account garbage collection and fragmentation.

The first delay thing is not just the compile overhead for numba. It also takes a long long time apparently for "warm up" of the SIMD or AVX instructions. Even if the code is precompiled, if you change the matrix & recalculate it's gonna take a whole long time again for the first run. In applications when you need only a few iterations this is really not worth it. If you are doing several iterations on each matrix like more than 10 times then yes it's worth it.
