Jetpack4.5.1 doesn't meet requirements.txt

[zeta0707]

Hi aelmiger,

Which jetpack do you use? I'd like to try again this project onto your verified jetpack version After clone your project, I failed to install requirements.txt.

Thanks!

Hey!

I cannot recall which version of Jetpack was used, but you can try changing the numpy version in the requirements.txt. Something like numpy>=1.18 should do the trick.

Hi,

OK. I will try your suggestion soon.

Thanks!

Hi,

I modified requirements.txt.

jetbot@jetbot-nano:~/lane_detection$ cat requirements.txt 
numpy>=1.18.4
scipy>=1.4.1
opencv-contrib-python >= 4.2.0.34

Then installed the required packages. Actually below log is 2nd log of install, then see already installed.

jetbot@jetbot-nano:~/lane_detection$  pip3 install -r requirements.txt
WARNING: pip is being invoked by an old script wrapper. This will fail in a future version of pip.
Please see https://github.com/pypa/pip/issues/5599 for advice on fixing the underlying issue.
To avoid this problem you can invoke Python with '-m pip' instead of running pip directly.
Defaulting to user installation because normal site-packages is not writeable

But I see core dump. Any advice?

jetbot@jetbot-nano:~/lane_detection$ python3 lane_detection_script.py

Thanks!

you just need to add "export OPENLAS_CORETYPE=ARMV8" in .bashrc
