Can't build SciPy from source because pybind11 missing

Question

I have ssh'ed into my Raspberry Pi 3b+ on my Macbook. I am trying to install SciPy on Python 3.8, but apt-get does not work and installing through pip freezes my Raspberry Pi. I have even tried increasing swap size, but it still freezes. As a result, I am trying to build SciPy 1.6 from source, but when I run sudo python3 setup.py build and sudo python3 setup.py install, it returns Error: 'pybind11' must be installed before running the build.

I have installed pybind11 using python3 -m pip install pybind and python3 -m pip install "pybind11[global]". I can even import pybind11 in the python shell. Here is my list of packages:
