[@therealdaniel451]

It's a nice tutorial but I think the performance comparison is highly irrelevant for practice. It is a comparison against a manual matmul in Python - and nobody does this. Ever. I benchmarked myself and get the same order of magnitude and (in most cases) still more performance with 0 optimization and simply using PyTorch on GPU, like any AI dev would. No researcher will ever invest time to optimize on that level, if running PyTorch (and the like) on GPU gives similar or more speedup. Don't get me wrong, Mojo looks like a really interesting approach but the huge win of Python - including in AI - comes from enabling the dev to do complex stuff without optimization in just a few lines of code and outsourcing the "heavy lifting" automatically to CUDA and the like. Thus (1) Mojo will never win a huge user base over if the implementation takes much more time and, what is far more important, (2) Mojo needs to compare against PyTorch and the like and *perform better* there, not against vanilla Python.

[@baldeagle6531]

So i did a little research with the exotic behaviour of Int datatype: Int8 stores 127 positive number, null and 128 negative numbers. So when you type 127 in Int8 you'll get 127, but when you type 128 you'll receive -128 and further initial increment just reduces the negative num by +1 (Int8 129 = -127 and so on). Also when binary grid overflow occurs the bit pointer just continues to move from left to right overlapping past bit. As shown in the video 6000 became 112. The representation of 6000 in binary is 1011101110000 and for 112 is 01110000, as you can see these are the last 8 bits of 6000 in binary.

[@alelondon23]

not exotic behaviour. when a number doesn't fit the datatype (like 6000 into a en.wikipedia.org/wiki/Two%27s_complement signed 8-bit integer) the extra digits get truncated and the implementation may rise some "overflow" flag.

[@vulamnguyen9453]

58:02 I think it would be better example for "rhs" if you overload operator in that struct. Such as fn __add__(self, rhs: Banana) -> Float32: return self.Length + rhs.Length. Since you only return self.Rype or Length or Color, include "rhs" argument wasn't necessary.

[@peterzelchenko]

@30:54 people are going to get confused when Elliot says an Int8 can go from minus 255 to 255. That's not correct. If you take 2^8 bits (two to the eighth power or 2x2x2x2x2x2x2x2) you get 256 available values within any 8 bits or binary digit positions. In a signed integer, this is represented in decimal from minus 127 down to 0 and then up to to 127, totaling 255 possibilities (plus "negative 0" gives you 256, but nevermind that). So it's really only minus 127 to plus 127, not minus 255 to 255. The trick is the "sign bit" -- the leftmost bit position of the 8-bit byte that can of course be either 0 or 1. If 0, then the number is positive (7 bits going from 0-127) and if 1 the sign bit is set and the number is negative (7 bits going from negative 0 to negative 127). The other 7 of the 8 bits are used for the actual number. With an unsigned integer UInt, the sign bit is not used for negative numbers, but it is used instead for an additional 128 positive integers to take you from 0 to 255. This is convenient if you don't have any intention of the variable to go negative. A signed Int16 or 16-bit integer can give you 2^15 possibilities in both the negative and positive direction, or minus 32767 to +32767, and a 32-bit integer can give you (2^32 / 2) over 2 billion in either direction. Python is nice because it doesn't bother us with this, but this is also why Python is not as efficient as Mojo or C. So, when you start wanting high performance speed in your code, you have to start considering the bit and byte level to speed up many of your operations. Eventually it becomes second nature to know what purpose the variable or data element is being used for. In general, the difference between a high-level developer and a regular programmer is more or less this understanding and not a great deal more. If you learn this well (and it's not really that impenetrable, I promise), you will have a richer understanding and a new level of ability with computers.

I’m sure we’re a few years away from this but, imagine a game engine built in Mojo using Mojo as the scripting language. ❤

[@noblackbox]

The 'let' keyword is no longer supported in Mojo as of the 24.2 release. Instead, Mojo now only supports 'var' variables and undeclared variables (similar to Python) inside 'def' functions or in top-level code in the REPL. Therefore, you should use 'var' instead of 'let' for variable declarations.

Thanks for the intro! Mojo looks very promising,, but anything that needs a huge speedup would be called from a Python library containing compiled functions. If there's no existing library, it takes extra time and effort to create a custom one in C or some other language compatible with the Python ABI. Yes, great advantage that Mojo compiles directly, but it is definitely possible to get good performance with Python.

[@JeremyJanzen]

Thanks for the video. Honestly I’m not sure it really makes sense from a beginner perspective because a beginner would just be confused by Mojo, as they don’t understand the underlying Python. IMO it would have made more sense to write a tutorial for people who already know Python and how they could use this to speed up their programs.

[@LeePenkman]

nice, with the speed test with cuda/torch sometimes it delays the initialization of a lot of the cuda packages untill you start using torch. so can mean moving a few 100mb over once at the start of the program. Just didnt want anyone to make the mistake - gpu is going to be much faster at doing most things esp parallellizable stuff. Amazing tutorial thanks!

Thanks a lot! Free education is amazing. I have a question - does Mojo require powerful hardware to run? It can do a lot and im afraid I may not have what it takes hardware-wise for it to be used optimally... Or could it just be run with the same specs like Python?

[@StatoLNL]

Great intro into the future of IaaS

[@ertagon]

Correct me if I am wrong but almost all if not all major AI frameworks such as Tensorflow or PyTorch are not "written" in Python. To the best of my knowledge (and I could be wrong here) they act more like wrappers with low level mathematical operations (and thus AI training) taking place in compiled languages, I suspect it's C++. So where is this improvement in AI model training (as mentioned in the video 5:25) comes from? True if you are doing anything outside of those frameworks you are indeed stuck with Python speeds. But I don't believe the training speeds themselves are affected in any way.

[@vulamnguyen9453]

When you build a Time Distributed model such as CNN + LSTM for action recognition or video classification, you have extract feature embedding from N frames and then feed them one by one to LSTM (you have to use for loop in this case). And that part is a bottleneck since you use python for loop. Those bottleneck occur in many parts of the code where you don't perform tensor operation. You can look for PaDiM (an unsupervised method for anomaly detection), you can see that there are many parts that have that kind of bottleneck. Hopefully, Mojo can speed up those parts.

[@michaelorlev9925]

Wonderful tutorial, a question from a noob. With the "owned" arg, does the function change a parameter declared as "let"? Or does the function create it's own copy that is disconnected from the "let" parameter, and therefore mutable now?

Technically Python is a compiled language and it even has a PVM like JVM. However, the slowness comes from 10 different things in python. BTW, thank you for this course. Fun fact, Mojo can load Python libraries as well.

No it is not a compiled language just because it has a bytecode. There’s a big difference in architecture between a compiler and an interpreter and CPython is definitely the latter.
