Attempting to run IntelligentObjectAvoider, I hit a RuntimeError:
File “init.pxd”, line 998, in numpy.import_array
RuntimeError: module compiled against API version 0xc but this version of numpy is 0xa
and then I "tried to fix my own car"
Configuration:
- Raspbian For Robots (git rev-parse HEAD: 91495583be661dc7aaf83b15c200945323d24b10)
- pip freeze, pip3 freeze
- gopigo3==1.2.0 (both pip and pip3)
- DI-Sensors==1.0.0 (both pip and pip3)
- pip: numpy==1.12.1 , pip3: numpy==1.15.1 (after pip3 install numpy --update)
Details:
pi@Carl:~/Carl/Projects/IntelligentObjectAvoider $ python3 robot.py

ImportError: numpy.core.multiarray failed to import
Thinking I can do this alone, I tried upgrading numpy but now I’m even deeper in trouble:
pi@Carl : ~/Carl/Projects/IntelligentObjectAvoider $ sudo pip3 install numpy --upgrade

ImportError:
Importing the multiarray numpy extension module failed. Most
likely you are trying to import a failed build of numpy.
If you’re working with a numpy git repo, try
git clean -xdf(removes allfiles not under version control). Otherwise reinstall numpy.
