Files are in a 7zip format (.7z) but xarchiver doesn’t recognize them, through the GUI or command line. Man on xarchiver says it goes by the file header rather than the extension—do I need to search for a specific archive of ROMs created on a Linux file system? Can I convert or am I missing something dumb Don't know what gui tool will do it but sudo apt-get update sudo apt-get install p7zip-full This will install a 7z command that should let you extract from the .7z file. https://www.howtoforge.com/tutorial/how-to-install-and-use-7zip-file-archiver-on-ubuntu-linux/

Well I got the model running and it took my Pi 4 about 58 minutes of sitting at 99% RAM usage to generate the following:quote:2015 Last time I tried to mess with this I was looking into converting the GPT-2 model to a TensorFlow Lite model but many of the operations it uses weren't supported by Lite.

P7zip worked great, thank you. I think I need to nuke my card and start over, however, I attempted to install Retropie on top of the OS (using the instructions here https://retropie.org.uk/docs/Manual-Installation/) and now my system hangs on a black screen at boot. Is it possible/desirable to do a desktop install of Retropie and launch as needed? I’d like to keep this as a device that I can use as a workstation primarily, but launch the emulator front end when it’s hooked up to the TV

namlosh posted:This is actually cooler than suggested by the content lol Nope, still GPT-2. I haven't looked at the file sizes/complexities of GPT-3 but I'd imagine it would take even longer to generate. I trained the model on some movie scripts and YouTube video subtitles on my desktop PC, but I had to use the 355M base (the second smallest) because anything bigger uses too much VRAM for my 1080 Ti to handle. I was originally trying to do this as a replacement for a Markov chain in a Discord bot but the generation time doesn't really lend itself to that. I might move down to the 124M model and see if that's any better. e: Actually, the GPT-3 model isn't even available for download. It's only through an API and you have to sign up for a waitlist to get access. And I'm guessing "shitposting chat bot" isn't a valid reason to put on the application. e2: also it's $100 a month minimum after the first 3 months lmao i vomit kittens fucked around with this message at 00:43 on Oct 31, 2020 |

If you need access to GPT-3 I might be able to find the inside line. I know a few people who have access pretty much to gently caress around with it. I got to use a very early beta GPT-3 based chat bot a few months ago and it was pretty amazing. Definitely would blow any Markov based method out of the water. I don’t recall what the look back was on it but it was a lot. If you’re using this for biz, I think the credit card company brex had some deal where you could get AWS credits for signing up. You could then use that to train on AWS sagemaker with a much better GPU.

I guess it doesn't hurt to ask because yeah I'd love to mess with it provided I don't run the risk of somehow getting someone else's access revoked or cost them anything. Just to be up front though, it's 100% not for any sort of productive or thought-provoking application, it'd literally just be relegated to trying to get it to say stupid poo poo every once in a while in a Discord of ~75 people.

The Raspberry Pi 400 was just announced, it's a Pi 4 4GB built into a keyboard for desktop use more than anything, I guess. Kind of a cool idea if you want to do that with it since the price is reasonable ($70 or $100 for the kit): https://www.raspberrypi.org/blog/raspberry-pi-400-the-70-desktop-pc/ https://twitter.com/Raspberry_Pi/status/1323178724678840321 There's a review up on Explaining Computers as well as dozens of other places I'm sure: https://www.youtube.com/watch?v=P1E5xszQqV8

I wouldn't buy one myself but it's definitely a cool idea and would probably be great for a kid getting into programming/electronics. It also has a faster processor than the regular Pi 4s, 1.8 GHz vs. 1.5. I don't know how significant of a jump that is but I was considering buying a second Pi 4 so it'd be nice to see a faster CPU show up on them.

Lazyhound posted:Is the 4 actually fast enough for desktop use? Trying to do anything GUI-based on my 3B is like pulling teeth. Yes, it's about four times faster than the 3B. Comparable to a cheap laptop, by most user reports - i.e. not great but totally fine for grandma's email and Facebook. If they released the 8GB model as well, it would probably let you open a few more browser tabs.

Home-computing has come full circle. Considering that this, again, feels optimally placed in turning an existing TV into a computer, the fact that the pi has (I heard) problems with youtube playback is a big problem.

VictualSquid posted:Home-computing has come full circle. The regular Pi 4 is probably still better for this use case because you can stick it under the TV and use a wireless keyboard and mouse with it. You could do it with the Pi 400 too, but it takes more room. But it's impressive that you can get a basic computer for what, 200 bucks if you have to buy a screen? And it cools a lot better than the Pi 4, too.

Re: Pi 400 - the Engadget article claims they'll also sell it in a $70 version that's just the keyboard/Pi without the accessories, but none of the resellers listed (at least on my admittedly quick look-see) seem to have that as an option. Anyone know of anywhere actually selling that? I already have all the necessary accessories so would rather not spend the additional $30 and have to find a drawer to toss them in.

Lazyhound posted:Is the 4 actually fast enough for desktop use? Trying to do anything GUI-based on my 3B is like pulling teeth. Yeah with 4gb memory or more and Ubuntu 20.10 desktop it's a solid and perfect desktop machine. Ditch Raspbian though, it's using such old and janky desktop gui that it's not worth it (they need to support all the super low end pis too so the whole ecosystem is held back). But be ready for some architecture pains, aarch64/arm64 is still a crapshoot of finding stuff that's compiled and ready to go or completely missing. Lots of little things like browser extensions, etc. don't have good aarch64 builds. But it's worth trying if you have a pi 4.

The German reseller has the same (preorder) message on both models. They say they have a shipment of both incomming in the near future. They are even saying that they probably will be able to ship the loose 400s before the kits.

Some Goon posted:So tempting, so not at all needed. Compared to that it's going to be a step down, but not as bad as you think. My 4GB model is faster than the cheap x86 4 core Atom 2GB memory tablets but not as nice as a Ryzen 3 for some comparison. You _have_ to get the OS off the SD card and onto a SSD though. If not, it feels like dogshit molasses.

Or use as a terminal for your home server. And it sounds like it's edging in on "a used optiplex" for a basic home computer.

Does anyone have a dropbox-cli usable from within the cli? I'm on a RetroPie image and I'd like to use dropbox for backing up/retrieving configs and files. I did put on i3 so can xinit i3 then go into Chromium, but I feel like it's a weak move when command line tools would be available.

I basically ordered one immediately yesterday when I saw a video of it pop up on my screen. It's like it was tailor made just for me. Seems to come with all the stuff that I wished for in 2015 the last time I tried the RPi2. Still very  about it.
