So i had issues installing inputshaper on my Opi Zero, so i cloned the SD from another printer with the same Opi zero but the same issue still persist. Even took the SD back into the printer it was cloned from and it worked perfectly.

all the info i find about installing numpoy has not worked.

What else can i do?

When i run SHAPER_CALIBRATE i get the following error:

Failed to import `numpy` module, make sure it was installed via `~/klippy-env/bin/pip install` (refer to docs/Measuring_Resonances.md for more details).```

(running the install in putty failes)

Thanks, but i have 7 more printers, all with the same orangepi, all running Inputshaper with the same adxl connector via a rpi pico. I think i just have to start all over with a freh install.

Numpy is not installed by default, you need to add it manual.

Please provide the error messages there are a million reasons why a install can fail

@fresh furnace any idea?

fresh furnace Jan 31, 2023, 5:18 AM

#

Lets see if there is a precompiled wheel on pipy

#

Maybe missing deps like libatlas3 libatlas-dev?

#

So a quick search on piwheels tells me there is no precompiled version for py 3.10 they all have 3.9 requirement. So, I guess we have to get it compiled. I do some tests this evening on my oranges.

#

What OS is used? The original Image provided by orangepi?

molten star Jan 31, 2023, 6:44 AM

#

original armbian image, yes

fresh furnace Jan 31, 2023, 8:30 AM

#

Armbian != OrangePi OS

#

So, a real selfbuild armbian or the Orangepi patched version of armbian?

#

@molten star Any updates on this?

#

And btw I forgot a dependency. Its also libfortran5 needed

molten star Jan 31, 2023, 9:31 PM

#

armbian from the armbian site

#

Ok, Ill try to reproduce the next days.

#

I use a Opi4 lts for this but I think shouldnt matter
