Solution:

Re-create a soft link from OK3568-linux-source/buildroot/output/OK3568/host/bin/python to python3.

cd buildroot/output/OK3568/host/bin

rm python

ln -s ln -s python3 python

After re-establishing the soft link, recompile. Use ls -l python to check if the soft link is successful.

Solution:

Delete the python-related files in OK3568-linux-source/buildroot/output/OK3568/build/ and recompile.

This is because pip installation depends on SSL, and if the full compilation in step 1 was done using python2 for SSL compilation,

pip requires python3. So, after re-linking to python3, recompile the python-related files.

rm buildroot/output/OK3568/build/python-* -rf

./build.sh buildroot

After compilation, burn and verify the file system. Opencv-python related tests can then be performed.
