Oct2py and Matplotlib installation problems

[Leloup]

Bonjour,
I developed some functions with Matlab and I'd like to move to Python. In first time, I modified these m functions so that they are compliant with Octave. Manually, I rewrote only two m functions in Python 3.5. However, I read an article whom was promoting for Oct2py. I tried to download this module but that's when the trouble started. The Oct2Py downloading failed. I downloaded the last version of python, 3.7. I loaded the following modules:
Package Version
---------- -------
kiwisolver 1.0.1
numpy 1.15.4
pip 10.0.1
pyparsing 2.3.0
pytz 2018.6
setuptools 39.0.1

In summary, I need Matplotlib. Dependencies are numpy, dateutil, pytz, pyparsing, kiwisolver, cycler and setuptools.
The Dateutil and Cycler installations fail.
"Could not find a version that satisfies the requirement six (from cycler==0.10.0) (from versions: )
No matching distribution found for six (from cycler==0.10.0)"
"Could not find a version that satisfies the requirement six>=1.5 (from python-dateutil==2.7.5) (from versions: )
No matching distribution found for six>=1.5 (from python-dateutil==2.7.5)"

In summary, I need Matplotlib functional with python 3.7 in the hope that python works with Oct2Py.

Do you have any idea How do?

Regards,

Leloup

You can try to install six perhaps

Output:
python -m pip install --upgrade six

Thank you Gribouillis

In fact, it was a problem of proxy.
I downloaded from my mobile phone set as modem. That works now.
