Hi there I have run the stressberry test following your instructions however when i try to plo the graph using the following command MPLBACKEND=Agg /home/pi/.local/bin/stressberry-plot mytest.out -f -d 300 -f -l 400 1600 -t 30 90 -o mytest.png --hide-legend --not-transparent --line-width 2 I get the following error RuntimeError: module compiled against API version 0xe but this version of numpy is 0xd Traceback (most recent call last): File “/home/pi/.local/bin/stressberry-plot”, line 10, in sys.exit(plot()) File “/home/pi/.local/lib/python3.7/site-packages/stressberry/cli/plot.py”, line 9, in plot import dufte File “/home/pi/.local/lib/python3.7/site-packages/dufte/ **init**.py”, line 1, in from .main import legend, style File “/home/pi/.local/lib/python3.7/site-packages/dufte/main.py”, line 3, in import matplotlib as mpl File “/home/pi/.local/lib/python3.7/site-packages/matplotlib/ **init**.py”, line 107, in from . import \_api, cbook, docstring, rcsetup File “/home/pi/.local/lib/python3.7/site-packages/matplotlib/rcsetup.py”, line 26, in from matplotlib.colors import Colormap, is\_color\_like File “/home/pi/.local/lib/python3.7/site-packages/matplotlib/colors.py”, line 82, in from matplotlib import \_api, cbook, scale File “/home/pi/.local/lib/python3.7/site-packages/matplotlib/scale.py”, line 18, in from matplotlib.ticker import ( File “/home/pi/.local/lib/python3.7/site-packages/matplotlib/ticker.py”, line 179, in from matplotlib import transforms as mtransforms File “/home/pi/.local/lib/python3.7/site-packages/matplotlib/transforms.py”, line 46, in from matplotlib.\_path import ( ImportError: numpy.core.multiarray failed to import Can you please help to advise please, Thanks ---

Have you been through the forum thread for Core’s Stressberry tutorial? > [@How to Stress Test Temperature on Raspberry Pi (Stressberry)](https://forum.core-electronics.com.au/t/how-to-stress-test-temperature-on-raspberry-pi-stressberry/6887): > > Graham just shared a new tutorial: [“How to Stress Test Temperature on Raspberry Pi (Stressberry)”](http://core-electronics.com.au/tutorials/how-to-stress-test-temperature-on-raspberry-pi.html) [image] First of all, why subject your Raspberry Pi to this level of stress? In the case of Raspberry Pi 4, the A72 CPU is so powerful that it can overheat if it doesn’t have enough cooling. This results with the CPU being governed (slowed down) to red… [Read more](http://core-electronics.com.au/tutorials/how-to-stress-test-temperature-on-raspberry-pi.html) ---
