I am currently running Yocto-distr on a Cisco Router (so this is embedded-Linux system call Guest-Os). I already have python-2.7.3 version installed. I am currently to install Numpy. However, the installation wasn't successful, and I have no idea what to look for in the error description. What should I do?

Python numpy not found or no module named 'numpy' error appears when the module is not installed in the current working environment. Install the module using pip or conda to fix this issue. but make sure that you have installed it in current working environment.
The first solution to remove this error is to first upgrade the pip command. After upgrading try to install the NumPy version using the pip command. But make sure to check the version of the python.
NumPy 1.22. 0 is a big release featuring the work of 153 contributors spread over 609 pull requests. The Python versions supported by this release are 3.8-3.10.
You are missing numerous dependencies which are required to compile numpy.
Numpy is developed in a mix of Python, C and Fortan for speed. You need the python header files, a fortran compiler, gcc and the BLAS/LAPACK libraries.
On Ubuntu the following dependencies are listed for numpy 1.8.1 so maybe you can infer what to install from here:
Looking at your errors it seems like your missing the BLAS/LAPACK libraries and a fortran compiler:

You already seem to have a version of gcc though
Hope this helps
