I'm working behind company firewall and I had trouble installing packages through Python Install packages().
I have by-passed the issue using jmp.utils package, as suggested in JMP 18 Help. I have edited the jpip.bat file manually modifying the pip command like this:
"C:\Program Files\JMP\JMPPRO\18\jmp_python.exe" -m pip %* --proxy http://myproxy:myport
I think this suggestion could be included in the help quite easily.
As an even better solution, I would suggest to add a "proxy" argument to the Python Install Packages() function.
