Robowaifu Simulator Robowaifu Technician 09/12/2019 (Thu) 03:07:13 No.155
What would be a good RW simulator. I guess I'd like to start with some type of PCG solution that just builds environments to start with and build from there up to characters.

It would be nice if the system wasn't just pre-canned, hard-coded assets and behaviors but was instead a true simulator system. EG, write robotics control software code that can actually calculate mechanics, kinematics, collisions, etc., and have that work correctly inside the basic simulation framework first with an eye to eventually integrating it into IRL Robowaifu mechatronic systems with little modifications. Sort of like the OpenAI Gym concept but for waifubots.

>>5501 >Though, I thought OpenAI is a foundation and their software is open source, so that part shouldn't be a problem. They are a good example of the double-standard corruption going on in Silicon Valley. They're happy to receive tax-exempt, non-profit donations (to the tune of US$1Bn a pop https://web.archive.org/web/20190723065252/https://news.microsoft.com/2019/07/22/openai-forms-exclusive-computing-partnership-with-microsoft-to-build-new-azure-ai-supercomputing-technologies/ ), all the while keeping the source closed to `protect us` from dem ebil_nahdzees. It's literally George Orwell's Ministry of Truth alive and well today, but in a tail-wagging-the-dog form of it (ie, Industry tells the Government what to do). But don't get me started... XD
>>5501 OpenAI gym is open-source but the documentation is atrocious for custom environments. When I used gym retro to build a library for playing SNES games with AI easily there was a bug in some games with hi-res mode and absolutely no documentation to work with. After digging in the source code for awhile I found they buried the functionality of the emulator and there was only one dude working on it. For the billions of dollars they're receiving in funding you'd think they'd have more than one guy on open-source code. Similarly with the code they release for their papers they only release the bare minimum with no documentation rather than the actual full code they used in their paper. Another issue is I want to have full access and control over the simulation while prototyping parts. One of the reasons why I use PyTorch instead of Tensorflow is because it uses a dynamic graph for models, whereas Tensorflow's is static and cannot be changed while running. In PyTorch you can plug in and disconnect other networks at runtime and shutdown various parts of a network to only train specific parts. It's a lot more robust and gives more freedom with what you can do with it.
>>5504 >OpenAI gym is open-source but the documentation is atrocious for custom environments. Fair enough, my little rant >>5502 was about them sequestering the 'open' source code of GPT-3, and instead doling it out to only the chosen few and for a very hefty fee, no doubt. And even if they made access to a run-time solution for their GPT system entirely no-cost, I still don't consider that 'open' by our standards. You still wind up entirely beholden to their cloud-based system for your waifu to function. One wrong peep out of you on social media one day and they pull the plug. The only way around this I can think of is we somehow create our own models. And surely we can't be the only group desiring freedom from this type of commercial bondage by Big Tech. There must be literally hundreds (or thousands?) of groups interested in truly open conversational AI, and in a diverse set of fields as well. As things stand, IMO there is very little 'open' about what OpenAI is doing.
>>5506 The closest thing I know of is Lex Fridman's discord server. It has a lot of people interested in AI sharing and discussing various papers and their own projects. They're not really focused or collaborative though. I only know of a few people really innovating with AI on their own. Most of the discussions I see online are by beginners still learning the basics. It's an extremely difficult field to get into that requires time and money and it's constantly evolving. This is the reality we face against Big Tech. I think our best bet is to keep working on our projects and hope they attract the right people. My vision at the moment is to finish the Blender SDF add-on so people can quickly design robots in Blender, export them to Bullet, then drag and drop SDFs into the simulation window to automatically start training. This easy workflow should attract a lot of creative minds, and under the hood there could be different learning algorithms and parameters for people to tune. None of this 2 GB bloatware with 500+ dependencies. People who want to make robots can focus on robots and those who wanna make AI can make AI. Our efforts will synergize that way.
>>5510 Sounds like a good plan Anon. You plainly are ahead of me in keeping up with current hobbyist trends. I'd suggest you continue on with your plans. I consider you a leader in this, at least insofar as we on /robowaifu/ are concerned. Godspeed.

>>5510 >>5511 BTW, I've got Godot successfully building today on my box, and hopefully I can soon be up to speed and follow along with you Anon. (3.2 branch b/c my little machine doesn't into Vulkan) https://github.com/godotengine/godot/tree/3.2 BTW there are good tutorials about the engine, etc., on the official Godot YT channel itself.
>>5510 If you ask about organized groups around people doing their own AI, then Huggingface comes to mind: https://nitter.net/huggingface I also recall them at least discussing to implement GPT3, but they were aware of the problem that it needs quite some powerful servers. There's generally a lot going on on Twitter and Reddit, it's just necessary to focus one that topic and not getting pulled into politics or other distractions... In my case, I first have to learn the math, otherwise it's pointless. Maybe I'm getting the Brilliant app soon, but first I'll try some other sites and Youtube channels. Also I want to move and buying a new PC after that, so that I won't have to move it.
>>5519 I imagine some months down the line I might be able to write an SDF importer for Godot. That way simulation training done in Bullet can be used in games and demos easily. >>5536 Yeah, Huggingface provides a lot of useful tools and models for tokenizing text and stuff. The models used in TalkToWaifu were produced by Huggingface. They're definitely leading in open-sourcing NLP and making it available for everyone.

This guy here makes interesting stuff with voxels: https://nitter.dark.fail/tuxedolabs - Very realistic environments. Youtube video: https://youtu.be/aAgVSTrqNOc - Not directly slicof life, but if one wants to learn about simulators and how to train AI in such environments, this might be useful.
>>8486 Wow, thanks Anon! That's pretty inspiring actually. I'll make time to dig through this guy's work and see if I can figure out what he's doing. Also, thank you for using nitter instead.
>>8491 You're welcome.

>>8501 I like the idea of creating a robowaifu simulator using voxels. I assume they are a pretty efficient way to create interactive physics, just from looking at the play from that vidya.
https://www.raylib.com/ might be interesting for simulators or virtual waifus. It's for gaming and works basically everywhere. Its very modular, modules can be used on their own.

>>8926 Ah, didn't look for it. Here: >>5810 >>2018
I am currently building a framework for 2D simulations, similar to dwarf fortress. The goal is to have a simulation that is as realistic as possible, while also using up as little performance as reasonable. I want to train multi-agents with evolutionary model optimization in the simulation; to test a few ideas on how to solve artificial general intelligence without having to bother with RobotVision and ArtificalMuscleMovement. Main goal is to solve general AI but I also want to try and solve NaturalLanguage using a new (?) approach. Going to be open source one day. (it's not my day-job to code this so progress is kinda slow. Anyone interested in it?)
>>9032 >Anyone interested in it? Sure ofc, Anon. We're always interested in that kind of thing here. Give us more details please.
>>9032 When I first got started with neural networks twenty years ago I made a simple evolution simulation in Game Maker with prey and predators. I've always wondered if they were given the ability to make different sounds and hear each other walking if they would've formed their own crude language eventually. I think that would be a fun project. I also want to solve general AI and feel that AI needs a more complex environment to really learn and grow. Most AI research focuses on maxing something out but in real life there's always something more to learn.
>>9034 >When I first got started with neural networks twenty years ago Wow that's pretty remarkable I had no idea anyone here had that kind of experience. It would be really nice if you conducted a beginner's class on these topics if you're up for something like that Anon. Cheers.
>>9045 Nah, I just played around with them for a bit as a kid after watching Chobits. I didn't really get into AI until around 2015. I could probably still teach things but there's lots of material for that on the web and I'd rather work on my own stuff.
>>9047 Oh haha I see. Well, it's still good to know you're here. Good luck with your 'stuff' Anon. I too found Chobits inspirational when I was young.

Has anyone tried PhysX? The most interesting feature of it for me is the GPU acceleration because PyBullet isn't really ideal for training thousands of iterations simultaneously. https://www.youtube.com/watch?v=K1rotbzekf0 https://github.com/petrikvladimir/pyphysx I'd like to start moving on from just learning about AI and actually apply it to some real problems that can be transferred to the real world. My goal is to start assembling my own robowaifu by the end of the year that can do some basic task like locate my hand and give me a high five or something.
>>9708 Yes, I've played with it bit (cloth sims & rigid body collisions mostly). Nvidia is plainly an evil Big Tech/Gov entity like the others, but they have made a remarkable push to make their GPU ecosystem easy to use if you at least have the basics of C programming under your belt.
While I wait for stuff to train I started working a side-project for playing video games with hindsight experience replay and became fascinated with the idea of repurposing the model afterwards for a piano simulation, similar to how they trained a robot hand to solve a Rubik's cube in a simulation then did transfer learning to the real world. A ton of progress has been made in making computer vision and reinforcement learning more efficient. Just two years ago it was probably too early to make any useful simulation and reasonably train an agent in it to do something interesting but now I think it's within reach. Maybe it's only an exciting idea to me but I think it would be a great way to demonstrate how far along AI has progressed and that anyone can make their own waifu play piano MIDI files given. We could demo other capabilities with it too like making her say the title of the song before playing and generate some virtual waifu hype. The simulation code would also provide a base for others to get started doing other custom simulations such as moving arms, balancing, and walking.
>>10073 >Maybe it's only an exciting idea to me No, I think it's a great idea Anon. I agree this would both be an innovative and useful way to build up training for AIs/Robowaifus.
Over the past few days I've gotten the latest Blender and UE4 working on my machines.
Someone mentioned Webots: Robot Simulator here >>10531 Link: https://cyberbotics.com/ >It has been designed for a professional use, and it is widely used in industry, education and research. Cyberbotics Ltd. maintains Webots as its main product continuously since 1998. >Webots core is based on the combination of a modern GUI (Qt), a physics engine (ODE fork) and an OpenGL 3.3 rendering engine (wren). It runs on Windows, Linux and macOS. Webots simulations can be exported as movies, interactive HTML scenes or animations or even be streamed to any web browser using webgl and websockets. >Robot may be programmed in C, C++, Python, Java, MATLAB or ROS with a simple API covering all the basic robotics needs.
>>1708 I apologize Anon, for not thanking you for this image when you posted it. I actually did appreciate it back then, but I was too distracted to share my gratitude at the time. So thanks! :^)
>>10073 We'd be interested to hear how both the training and your 'side-project' worked out Anon. Any news to share with us?

It's a complete system with physics, robot models, rendering stack and ML integrations. It would be of major help to the project if we developed a waifu-specific randomized (to facilitate sim2real generalization) sim-environment, and collected enough behavioral data traces to pinpoint the necessary behavioral patterns, similar to deepmind's recent imitation learning (IL) tour de force: https://www.deepmind.com/publications/creating-interactive-agents-with-imitation-learning If you choose this tool, feel free to ask for help if it somehow breaks. 1. https://github.com/facebookresearch/habitat-lab 2. https://github.com/facebookresearch/habitat-sim

>>16453 I managed to build and run it on debian sid with a script inspired by this document https://github.com/facebookresearch/habitat-sim/blob/main/BUILD_FROM_SOURCE.md Basically you clone the repo, checkout to the latest stable tag, update submodules recursively via the usual command git submodule update --init --recursive. I had to comment out a section in setup.py that deals with cmake path to make it work, like this: #try: # import cmake # # If the cmake python package is installed, use that exe # CMAKE_BIN_DIR = cmake.CMAKE_BIN_DIR #except ImportError: CMAKE_BIN_DIR = "" Ensure you have the cmake, debian packages and python libraries they require, then do the python3 setup.py install --bullet. It should build a several hundered source files via cmake and install the package. I managed to avoid using the conda for this, it's simply installed system-wide. When I/we will run multiple data-generating simulations at scale, some form of automated reproducible build & distribution system will be necessary, such as nix/guix or a container/vm.
>>16462 Thanks! I appreciate you're avoided conda for this. I prefer to stick closer to the hardware when feasible. I'll give your instructions a shot at some point.
