Unrecognized python functions when using same-module imports from a custom package

3 visualizaciones (últimos 30 días)
I am unable to get MATLAB to recognize functions within my custom python module if the file is importing anything from another module within the same package.
File Structure:
| content:
class ClassA:
def __init__(self, num):
self.num = num content
from file_a import ClassA
def function_b():
ca = ClassA(3)
print(f'My class A: {ca.num}')
In this toy example, the package is partially imported such that ClassA is available through the interperter via
But no functions from are available. Attempting access yields:
Unable to resolve the name py.python_test_lib.file_b.function_b()
I've tried various syntaxes for the import statement including
import ClassA
from .file_a import ClassA
from python_test_lib.file_a import ClassA
import file_a

From my understanding you want to call python functions in the matlab code. You can do this by setting python path and calling functions as follows:
Set up Python and Python path
pathToFile = fileparts(which(''));\
if count(py.sys.pathToSpeech) == 0
call python function
pyOut = py.file.function_name(inputs to the function)

The python path is already set appropriately. As I said, I am create an instance of ClassA through the interperter. However, function_b is not available and I believe that is due to the fact that it is importing from file_a within the same package. My question is what is the appropriate syntax/file layout to be able to handle these inter-package imports?
If you try setting up the files exactly as described the problem should be evident
