Does mitmproxy not work in python installed in JMP environment?

[#1]

I checked with 

jmputils.jpip('list')

mitmproxy was successfully installed

But it doesn't work in python code.

Thanks!

Doesn't work in what way?  Does import mitmproxy fail? If so try restarting JMP and seeing if it's now visible to JMP.  Otherwise how about an example?   What have you tried and why doesn't it do what you are expecting?

Note to all: The package mitmproxy is a Man-In-the-Middle HTTPS/TLS web proxy for intercepting web traffic.  I'm assuming the use case here is separately launched mitmproxy and use of JMP and mitmproxy's Python-API to control the proxy from JMP.
