Add a tutorial to install on a Raspberry Pi

[borisrorsvort]

Documentation Is:

• [ ] Missing
• [x] Needed
• [ ] Confusing
• [ ] Not Sure?

Explanation

I guess the ideal setup would be to install it on a raspberry pi or similar board, make it listen in the current room, and plug it to your favorite speakers.

Proposal

It might be nice to add some tutorial about small boards install.

Hello @borisrorsvort,

Thanks for suggesting, and yes, I plan to create such contents later on.

However, if you want to get your hands dirty by doing it, then you are more than welcome 😉

[asabya]

@louistiti, can I hijack this one?? 😅😅

[louistiti]

Hello @Sab94,

Yes with pleasure! Let us know once you have something.

[Thibaud-A]

Hello,

I tried to do it on my own but unfortunatly I got this error : If you get the way to fix it by loading another library it could interrested me ;-) I'm on a Pi 2 B.

[mbwhite]

I've started on some notes here... https://gist.github.com/mbwhite/2de7326d4680591101a27a53315a11b8

At present though I want to learn more about how Leon is working on vanilla ubuntu before heading back to the PI.

[nogarcia]

I have an older Raspberry Pi to test this on, and I could test it once I get back from traveling at the moment. I had a newer Pi 3, like @mbwhite's but I broke an I/O component while testing the GPIO pins.

[louistiti]

Nice! Looking forward to see that then. I'll also need to jump into that topic later on.

Enjoy your trip! 😄

[kominoshja]

I'm planning to write a blog about installing Leon on Ubuntu 18.04 if that helps anyone

[nogarcia]

@kominoshja, as I always run into one error and another, It'd be much appreciated. Thanks!

[louistiti]

@kominoshja awesome, let us know once you are done with it, I'll add the blog post link to the How-To section of the docs.

@Shrubhog oh really, do not hesitate to open issues then 😉

[nogarcia]

I have started building and installing Leon's dependencies. My notes can be found here. I have also diagnosed the issue with the Pi 3 and might fix it and test Leon there as well.

[nogarcia]

I will clone the latest branch first.

[nogarcia]

It seems my Pi does not have enough space to support it right now. I'll try deleting some other files later.

[louistiti]

Hello @Shrubhog,

Alright, thanks for keeping us updated and for handling it!

[shashwataggarwal]

@borisrorsvort @louistiti is this issue still open?

[louistiti]

Yes it is. I'm taking my time on my current project but will come back to work on Leon later on for sure 😉

[Tejaswgupta]

I see that it is not assigned to anyone . can I work on this.

[louistiti]

Sure you can work on it. I'll need to also take a look at it once I'll be back.

Hi did anyone managed to get it working on RPI? I did sudo install all the dependencies without issues. I am trying to install it on the Jetson NX, I have have some mysterious errors during the SUDO NPM INSTALL:

Not sure where this one comes from? the compilation did start ok and ran fine for like 5 mins and then crashed. seems to be related to some string function compile error on Arm8 (Jetson NX cpu), not 100% sure though.

thanks for your help on this.

Hi @Tetsujinfr, I don't know if you're still interest, but I manage to install Leon on a raspberry pi 3B+ by following standard instruction. I try to do it for 3 mouths and with nodejs version 14, it work !! Apparently some modification have been done a few days ago may be it thanks that ;)

That is a good news! Thanks for letting us know.

Hi, this month we have been working on compiling all Python stuff related upfront. Meaning, Leon does not need Python at runtime anymore.

Please try the three following commands and let's see how it goes and paste the report URL:

# Install the beta version of the Leon CLI
npm install --global @leon-ai/cli@beta

# Create a Leon instance based on the develop GitHub branch
leon create birth --develop

# Create a report
leon check
