hello guys, I’m not able to get numpy installed for measuring resonances… I’m no pro in Linux but I tried to activate the swap file like Klipper doc says but no way to get numpy installed. could you help please?
this command worked fine:
sudo apt install python3-numpy python3-matplotlib libatlas-base-dev
But this is what appears on my ssh screen when I try to install:
hitman@Ender:~ $ ~/klippy-env/bin/pip install -v numpy
