nrf connect sdk (ModuleNotFoundError: No module named 'elftools')

[Zack_Lee]

hi all, 

i download the project from github master branch, i also added  " pip3 install -r zephyr/scripts/requirements.txt " but still, i got the same issue. i had read from an article on the same issues mention, 

1. if i download "https://pypi.org/project/pyelftools/#files" where should i add the file to ?

2. is there any other ways to solve this problem ?

I too am getting this.
I have updated from ncs1.6.1 to 1.70; modified tag in west.yml; then west update.

I create a nw build of my project using SES->open nrf connect sdk project; then kick off a build in SES which exits with....

1> FAILED: zephyr/include/generated/driver-validation.h

have you gone through this chapter before upgrading to NCS v1.7.0? Otherwise I would recommend you to completely uninstall the NCS toolchain and reinstall it after upgrading all necessary tools.

Regards,
