ImportError: with stressberry . On the raspberry pi 4

[ChrisAFRcrew]

I have followed all the steps and now hitting a Error. Which I don't know how to fix. Everything is working just the plot is not. When I type in the terminal of the raspberry pi 4, I get an error message. "ImportError: bumpy.core.multiarray failed to import." I type it two ways, I typed "stressberry-plot out.dat -o out.png" , which I received the error. Than I typed, "MPLBACKEND=Agg stressberry-plot out.dat -o out.png" and still get the error message. Do have to take other steps. If so please let me know. Thank you

Hi, you just need to install numphy in your console. Follow this command:
pip install -U numpy
