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:

Try:

~/klippy-env/bin/pip install -v numpy==1.25.2

hitman47 · September 18, 2023, 5:15pm

Thank you so much! numpy 1.25.2 installed successfully!

Sineos · September 18, 2023, 6:13pm

For future reference:

v1.2.6 is brand new and no wheels are available
Once available, this problem should solve itself

mutlubasdas · September 19, 2023, 4:57am

Life saver!

Thank you very much! I have spent four days trying to install numpy in my pi4 in vain. How cool it is!

I’m having a similar issue where numpy won’t install on a pi3b / buster. Python version 2.7.16

python 2.7? you need to update your Python to 3.7 (or latest), then install numpy 1.25.2
