Printer Model: Kingroon KP3S Pro S1 MCU / Printerboard: BTT SKR Pico / Pi 4 via UART / Fysetc PIS I’m having some troubles when trying to run input shaper using a BTT SKR Pico connected via UART to a Pi 4 and the Fysetc Portable Input Shaper tool. The resonance tests run all the way through to 133Hz and then I get an error and I have been searching google endlessly and nothing is seeming to work. Error in remote calculation: Traceback (most recent call last): File “/home/pi/klipper/klippy/extras/shaper\_calibrate.py”, line 80, in wrapper res = method(\*args) File “/home/pi/klipper/klippy/extras/shaper\_calibrate.py”, line 152, in calc\_freq\_response if isinstance(raw\_values, np.ndarray): AttributeError: module ‘numpy’ has no attribute ‘ndarray’ I get this same error running both 'TEST\_RESONANCES AXIS=X" and “SHAPER\_CALIBRATE.” ---

I get the same error Printerboard: BTT SKR mini E3 V3.0 Please see attached klippy.log [klippy (11).log](https://klipper.discourse.group/uploads/short-url/7JFTbedDROp4tgLrcVezSMM3Xog.log) (1.7 MB) Did you manage to fix this? ---

Try uninstalling numpy and reinstalling, maybe a bit older version. Something like: ```auto ~/klippy-env/bin/pip uninstall -y numpy ~/klippy-env/bin/pip install -v numpy==1.25.2 ``` ---

Thanks so much. I had to force install numpy for some reason. Took me a while to figure this out, but all is working well now. ---
