Hey friends! I'm trying to setup CR on a Raspberry Pi. The unfortunate and difficult part of this is that most of it has to be done headless since Blender can't open the UI on a Pi. I've installed Blender and downloaded the .zip of the addon. Looking online, i've found some instructions to create my own .py script to install the addon for me.
import bpybpy.ops.wm.addon_install(filepath='/home/pi/Downloads/cr_022_bl280.zip')bpy.ops.wm.addon_enable(module='crowdrender')bpy.ops.wm.save_userpref()This seems to work as far as blender is concerned but this is what happens when CR tries to install. (sorry for the formatting) TLDR: ImportError: CrowdRender is not able to run because it can't import necessarycomponents, please e-mail us at [email protected] to report this. I know you want me to email you but I thought documenting it here might help some folks who have the same crazy idea as me!

Nick
I would like to test it.
Thank you
There's a new build thats working on Raspbian running in virtual box, I have no physical Pi's to test on, anyone wishing to test can simply reply to this thread, we can get copy to you :)
I'd like to add to this since it appears OP has not returned. I have 4 Raspberry Pi 4 B Rev 1.2 running Raspbian x86. Of those 4 1 has a WM and can install crowdrender via the blender GUI. The other 3 are headless and dump the message described above when attempting to enable crowdrender. All of the Pis are running the apt version of blender @ 2.79 and have no other configurations or addons, everything is pretty much vanilla except for ansible being installed on each pi. Let me know whatever else is needed to troubleshoot this issue.
Hello,
I would like to ask if this issue has been addressed? I am unsure which RPi model Nick is using but personally am using a couple of RPi 3s and Zeros that will only run up to Blender 2.78. The Crowd Render download page only has versions that support 2.79 or >=2.80 and I can‘t seem to find any legacy versions anywhere that will work with 2.78. I hope I can get some assistance with this, thank you very much!
Hi Nick, another thought, the OS you're using on the Pi, is it 32 or 64 bit?
G'day Nick, so sorry, I just found this post. We realised late last week that our forum had broken and we'd stopped getting notifications in our e-mails for new posts and replies to existing ones here in the forum.
So, while that is getting fixed, I am on cleanup patrol, and I came across your post just now.
Ok, So you're not forgotten about, which should never happen, are you able to submit a support ticket? https://www.crowd-render.com/report-a-problem that way we have a ticket in our tracker which will not get lost. We're actively working on tickets for the community in there.
