Working issue on python 2.7.15 or another version

[Punit Darji]

Hello all!
I was searching about Open source PLC softwares then I have found beremiz. I have downloaded and install all dependencies that mentioned in document. I have installed Python 2.7.15 or in short 2.7.6+ version.

Beremiz has already provided python version 2.7.6. But there is not installed PIP. when I try to install pip it gives SSL error

retrying (retry(total=1, connect=none, read=none, redirect=none, status=none)) after connection broken by 'sslerror(sslerror(1, '_ssl.c:507: error:1407742e:ssl routines:ssl23_get_server_hello:tlsv1 alert protocol version'),)': /simple/requests/

I have tried to install pip using easy_install command. Still fails to install pip.

My questions
1) How can I install pip in 2.7.6 that given version in beremiz.
2) How can I install beremiz on running python version 2.7.15.
3) How can I used beremiz on wxPython4.0 and python version 2.7.15 or grather versions.

Thanks and regards
