I'm trying to start with ANTLR . When I import module antlr it's working just fine , but if I try to import MyGrammarLexer and MyGrammarParser , it's shows that MyGrammarLexer and Parser aren't in lib. I Using PyCharm , I installed ANTLR with : pip3 install antlr4-python3-runtime my code is :
import sys
from antlr4 import *
import MyGrammarLexer
import MyGrammarParser
def main(argv):
input = FileStream(argv[1])
lexer = MyGrammarLexer(input)
stream = CommonTokenStream(lexer)
parser = MyGrammarParser(stream)
tree = parser.startRule()
if __name__ == '__main__':
main(sys.argv)
Maybe whom know why i can't import MyGrammarLexer and MyGrammarParser?
Please suggest!

I ran into this problem recently when getting the same error using the pddlpy python library. I was able to fix it by doing the following:
pip3 install antlr4-python3-runtime==4.9
The version 4.9 at the end is very important.
I found out that content of the package:
https://pypi.python.org/packages/0b/6b/30c5b84d203b62e1412d14622e3bae6273399d79d20f3a24c8145213f610/antlr4-python3-runtime-4.7.tar.gz#md5=190245a0fb4abf43568489a4b6e33aba
is different from the package installed by pip3.
I have replaced content of:
~/anaconda3/envs/py3/lib/python3.6/site-packages/antlr4
with content from the package I have downloaded and extracted manually:
~/Downloads/antlr4-python3-runtime-4.7/src/antlr4
It seems to be working now - in particular the following error:
ModuleNotFoundError: No module named '__builtin__'
does not occur.
After posting your traceback I can see the error is:
ModuleNotFoundError: No module named '__builtin__'
That means the package you try to import is using python2 syntax, but you're using python3.
You should use python2 if you need to run this package, but keep in mind that you probably want to search for a different one if this is a new project.
More about why it's not working here
EDIT
They released a package with python3 support, but it seems you installed/used something different. You should verify it.

You should install the module:
pip3 install greenlet

How to fix it?
It looks like someone published a functools package on pypi, so if you had run:
# don't run this!
pip install functools
You may have accidentally installed that package. If you encounter this error, I would:
pip uninstall functools
To make sure that the functools you are using are the base package functools.
(I ended up here because I attempted to use functools.cache, which seems to only be present in Python 3.8, not earlier.)
I had the same error recently and it was because I had a file called functools.py in my project. Renaming it fixed the issue.
How to get RO package working in Python 3? I managed to get it to work in Python 2.7, but when I install it manually as python3 setup.py install and then do import RO.DS9 I get this:
Traceback (most recent call last):

import UserString
ImportError: No module named 'UserString'
>>> exit()
In Python 3, UserString is part of the collections module.
As you can see on the RO page, this library does only support Python 2.6 and 2.7.
