[Paultino]

When executing "pip3 install -r nrf/scripts/requirements.txt",

according to the instructions on site

developer.nordicsemi.com/.../gs_installing.html ,

I get the following error.

Successfully built pyyaml
Installing collected packages: pyyaml

ERROR: pip's dependency resolver does not currently take into account all the packages that are installed. This behaviour is the source of the following dependency conflicts.
pyocd 0.32.1 requires pyyaml<7.0,>=6.0, but you have pyyaml 5.4.1 which is incompatible.
cmsis-pack-manager 0.4.0 requires pyyaml<7.0,>=6.0, but you have pyyaml 5.4.1 which is incompatible.

Hi,

It seems there is a version conflict with some allready installed modules. I suggest you install the nRF Connect SDK toolchain via the toolchain manager instead, which is the recommended approach on Windows. See Installing automatically. That way this will be encapsulated and not conflict with your other python installation.
