Python version >= 3.7 required (?)

[konstantinmamontov]

Hello,
"make up" command failed with last log entry:
...
RuntimeError: Python version >= 3.7 required.
The command '/bin/sh -c cd /opt/testbed/ && python3 setup. py install' returned a non-zero code: 1
make: *** [build/.depend] Error 1

my version:
CentOS Linux release 7.9.2009 (Core)
Docker version 20.10.11, build dea9396

Does this require installation into my operating system Python version >= 3.7?

Thank you.
