Nuitka: Scons: Argument list too long

$ python -m nuitka --version
0.6.2
Python: 3.6.7 (default, Feb 26 2019, 11:59:03)
Executable: /home/sridhar/devel/python-3.6.7/malenv3/bin/python
OS: Linux
Arch: x86_64

I’m trying to convert a sklearn/tensorflow based project into a standalone executable. The compilations exits because of the size of the argument list:

$python -m nuitka --follow-imports --standalone --follow-stdlib   -j 6 --show-progress run_server.py

Is it related to the warnings? How could I handle them? “–include-plugin-*” option is not available in nuitka.
