After hours of unsuccessfully trying to use objectpath in a Python3-script, I made the following simple experiment:
>>> from objectpath import *
>>> tree=Tree({"a":1})
>>> tree.execute("$.a")
Expected output: 1
Success with python (2)

>>> from objectpath import *
>>> tree=Tree({"a":1})
>>> tree.execute("$.a")

Error with python3:
Is there something wrong with my installation of Python3 ?
objectpath in P3 neither works in scripts nor on console

To run this in Python 3.x you should pip3 install objectpath otherwise it won't work.
See below how I ran your code:

To overcome the limitations of pickle, I switched to multiprocessing_on_dill.
This started to generate an error:
Traceback (most recent call last):
File "<string>", line 1, in <module>
File "C:\ProgramData\Anaconda3\lib\multiprocessing\spawn.py", line 107, in spawn_main
exitcode = _main(fd)
File "C:\ProgramData\Anaconda3\lib\multiprocessing\spawn.py", line 117, in _main
self = reduction.pickle.load(from_parent)
ModuleNotFoundError: No module named '__builtin__'
Is there a way to overcome it?
Surprisingly, it still references C:\ProgramData\Anaconda3\lib\multiprocessing\.
While multiprocessing_on_dill has its own folder C:\ProgramData\Anaconda3\Lib\site-packages\multiprocessing_on_dill with the same set of files.
I'd suggest you use multiprocess instead of multiprocessing_on_dill... the former is better supported, and maintained by the dill author (me). It looks like multiprocess_on_dill is looking for __builtin__, which is where the builtin functions lived in python 2... in python 3, they are in builtins

So, I think it's either you are running python 3, and using the python 2 version of the code -- or the module doesn't fully support python 3.

Could anyone please tell what I am doing wrong? Thanks.
As Yaroslav noted, this is most likely from running too old a version of Python, or you don't have the funcsigs package installed. For the latter, try pip install funcsigs

The module versions from my local and cloud differs.
By install correct module it works fine
