'PyError: invalid syntax' error when running python compiled code

[aresper]

I can successfully compile my python code, but when I try to run the binary I get the following error:

me@desktop:~/Python-sandbox/23-07-01-codon-typecheck-fix$ ./main_test 0 0
PyError: invalid syntax (graph_0_0_test.py, line 8)

Raised from: pyobj.exc_check:0
/home/alexandre/.codon/lib/codon/stdlib/internal/python.codon:1166:13
Abortado (imagem do núcleo gravada)
alexandre@insys-desktop:~/Python-sandbox/23-07-01-codon-typecheck-fix$ 

Since the code compiles, I was not expecting to get syntax error during execution.

Here are the snippets of the code I am trying to run:

This is the code from file main_0_0_test.py:

        if release_time in list(in_events_dict.keys()):

And this is the code from file graph_0_0_test.py, where I am getting the error in line 8 in the import statement:

And this is the code for file vertex_0_0_test.py:

@aresper Why are you importing:

from python import graph_0_0_test.JobGraph
from python import graph_0_0_test.IntervalGraph
from python import aux_0_0.ComputeJobs

Did you install graph_0_0_test as a python package using pip?

If it exists in the same directory as main_0_0_test.py, you can import it:

from .graph_0_0_test import JobGraph
from .graph_0_0_test import IntervalGraph
from .aux_0_0 import ComputeJobs

Hello @elisbyberi,

To import my python modules I used the procedure described here:
https://docs.exaloop.io/codon/interoperability/python

If I use the import statement as suggested I get the following compilation error:

me@desktop:~/Python-sandbox/23-07-01-codon-typecheck-fix$ codon build -release -exe main_0_0.codon
python.codon:1373:17-37: error: 'JobVertex' object has no attribute '__from_py__'
├─ main_0_0.codon:3044:17-37: error: during the realization of __from_py__(d: Ptr[byte])
╰─ main_0_0.codon:3097:5-9: error: during the realization of main(arg1: str, arg2: str)

@aresper Be sure the PYTHONPATH environment variable includes the path of mymodule.py!

Use from python import x only if "x" module has been installed using pip or python3 setup.py install. Note that import python has no effect and is not documented.

The error python.codon:1373:17-37: error: 'JobVertex' object has no attribute '__from_py__' indicates that the import is functioning. What isn't working is attempting to import a Python class definition in Codon. You cannot directly import a class definition from Python to Codon. However, you can call a Python function to return an object:

@python
def from_py():
    from dataclasses import dataclass

    @dataclass
    class T:
        a = 1

        def method(self):
            print(self.a + 4)

    return T()


t = from_py()


print(t.a)  # 1
t.method()  # 5

The equivalent in Codon would be:

@tuple
class T:
    a = 1

    def method(self):
        print(self.a + 6)


t = T()

print(t.a)  # 1
t.method()  # 7

Hello @elisbyberi,
I modified my files as suggested, thx.
I confirm my modules were not installed using pip and PYTHONPATH is pointing to the right directory.
However, I am having issues with the import:

me@desktop:~/Python-sandbox/23-07-01-codon-typecheck-fix$ codon build -release -exe main_0_0.py 
main_0_0.py:14:24-40: error: cannot import name 'JobGraph_from_py' from 'graph_0_0'
main_0_0.py:15:24-45: error: cannot import name 'IntervalGraph_from_py' from 'graph_0_0'

The initial part of my files currently look like this:
main_0_0.py

graph_0_0.py

vertex_0_0.py

Any ideas?
