How to debug errors

[emadsamir]

Let me start by thanking everyone that has worked on this effort so far.
Having said that, the documentation certainly could use some work as it's an uphill battle to figure out how to "make" this thing work.

Now to the main reason I decided to open this issue:
After I finally was able to make this work with lua 5.1 and python 3.8 on ubuntu,

1. I encounter occasional errors importing modules, calling functions or executing python code but without any debug information as to what is causing the errors, can someone point out how to get better insight into what's going wrong?
2. Is there good way to convert data from lua to python before sending to python side, or the other way when getting back?
