Hi Guys, can anyone help me explain why this happens? I tried to call azure.storage.files.datalake .net library from a python program with pytonnet (2.5.2), but I always got the following error: from Azure.Storage.Files.DataLake import DataLakeFileSystemClient
ModuleNotFoundError: No module named 'Azure.Storage.Files'; 'Azure.Storage' is not a package

the code is like this:

import clr
import sys

assembly_path = r"C:\Users\xxx\dlls"
sys.path.append(assembly_path)

clr.AddReference("Azure.Core")
clr.AddReference("Azure.Storage.Blobs")
clr.AddReference("Azure.Storage.Common")
clr.AddReference("Azure.Storage.Files.DataLake")

from Azure.Storage import StorageSharedKeyCredential
from Azure.Storage.Files.DataLake import DataLakeFileSystemClient
from Azure.Storage.Files.DataLake import DataLakeServiceClient

Does it work to export the PyScope and import it before I run my python file which depends on that scope? (for saving time)

Hi everyone, I have the following Signature in my C# Class: public bool GetPictureData(string strChannel, int objectID, out int width, out int height, out int[] imagePixels). In Python I try to use it like this: my_obj.GetPictureData('c01', 0, Int32(0), Int32(0), Array[int](0)) but I get TypeError: Cannot convert 0 to System.Int32[]. What am I doing wrong?

I get a "invalid syntax" error when I try to set a checkbox on a WinForms checkbox from Python. Here is the line I'm executing:
Host.LogToResultsCheckBox.Checked = True

The same line works fine from C#.
Does anyone know how to access a form property like that? I can read the property's state just fine from Python. I just can't write to it.

@fodangithub

@jdunne525 I believe its due to "boxing" process. check the document at http://pythonnet.github.io/ under its "Type Convertion" section theres some explanations

jdunne525

@jdunne525

@fodangithub Thank you! I ended up doing the following and it worked:

checkbox = Host.LogToResultsCheckBox.Checked;
 checkbox = True;
 Host.LogToResultsCheckBox.Checked = checkbox

Does anyone have any idea? Before compiling into .pyd, no error at all. After compiling, even tho reference being added, error still occurred. Appreciate if there is any answer to this issue

This issue occurred when .py calling .pyd with clr.AddReference. However if .py calling .py with clr.AddReference there was no issue at all...

Is it possible to create a python type from C#? I am trying to replicate some C++ code which uses PyTypeObject and PyModule_AddObject but can't figure out if it's even possible in c#. Thanks

Hi, I have a question, im doing some stuff with python 3.10.2 and the only functional option so far is the prerelease version, is there any plans to release that version soon or there is any planned date? thanks in advance :)

Hello! Could someone help me to setup python in .NET 5 for osX? Is anyone here?

jdunne525

@jdunne525

People are here, but you need to ask a direct question with a straightforward answer. It doesn't look like any of the developers are paying much attention to this.

So my problem is that, when I assign value to PythonEngine.PythonPath the application crashes on MacOS (no exception caugh despite try...catch block). I use Avalonia 10.12 and .NET 5. I assign this value @"/Users/kasperczyks/Desktop/PyCommon", I have folder on my desktop on macOS (Catalina 10.15.7) from where I want to import stuff. It works on windows, but I cannot make it run on MacOS. So should I use PythonEngine.PythonPathor rather Environment.SetEnvironmentVariable? I tried the second option multiple times but notnigh seems to work for my case

When I am using

var data = Numpy.np.array(new[] { 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14 });

        Console.WriteLine(data);

Any suggestion would work

This will print both lines and then hang. Killing the process takes a few seconds. Any ideas? .NET 6, Win10, pythonnet 3.0.0-preview2022-03-03.

Hi guys. I'm new to pythonnet, but I need to call a company DLL from my Python code for compliance purposes. Our AppSec guys told me I had to get off of Python 3.8.6 due to vulnerabilities. We're going forward with 3.9.10, but PyPi doesn't have a pythonnet-2.5.2-cp39-cp39-win_amd64.whl, so pip install fails on 3.9. Any idea when a semi-stable 3.9 version of pythonnet will be available? Is it even something the developers are working on in 2.5.2, or do I have to wait for 3.0.0 to be released?

Hi so I am trying to run a csharp file that I built using the dotnet command that references other dlls from a python script. I have been at this for days now trying to figure out how to run this. I thought the problem could be pythonnet wasnt supported with python 3.9 so I created a virtual environment and using pyton 3.8.8 and it still isnt working. The name space in my c sharp file is Payment_Application and I have all the dll files in the same folder that the dll I am referencing above in my path is. I have a rudimentary understanding of c sharp but enough to understand clr and the .net framework. I am running .net 6.0. Could it be I am not using .net core?

Hello community. I have just been introduced to Python.NET and have a use case question. I am moving a large number of complex forms from a VB.NET designer which produces XML (Specifically the GetCode function of the BasicHostLoader) into DJANGO web-based forms. I need to retain the ability for my users to create new forms or adjust old ones (altering the XML). Does Python.NET offer me a way to bridge that gap? My target functionality is for changes made in the VB.NET designer to be reflected in DJANGO views, but could work with any steps forward.

Hello all, I'm trying to make some test using pythonnet but isinstance asserts with MagicMocks of NET classes do not work as spected.
I'm using mock_instance = MagicMock(spec=NetClass) based on mock doc but isinstance(mock_instance, NetClass) returns False.
Any idea what I may be doing wrong? Is there any kind of workaround?

Hi all, Facing an issue after migrated from 2.5.2 to 3.x pre release versions . Basically the python int type is getting translated to PyInt inside my .net DLL and getting and error -- this is happening when I pass my python int as a value in a .net dictionary. this was working earlier in 2.5.2 version where the int was getting converted to System.int32

System.InvalidCastException: Unable to cast object of type 'Python.Runtime.PyInt' to type 'System.IConvertible'.
at System.Convert.ToInt32(Object value)
at ImageOCR.TemplateElement..ctor(Dictionary`2 paramDict)

Any one faced similar issue ?

Hello,
I have a .NET dll that I want to use in my Python project. One function returns a Matrix as a .NET object. If I print the variable in Python it returns INT32[,]. In .NET I can get the data with a cast like this ((int32[,])Matrix). How can I do that in Python with Pythonnet?
Best regards

So I'm creating a python extension for an existing application. The extension loads correct, and I can execute python code. I can call back into the CLR for things like System and Debug but whenever I try to add reference and import back into the CLR for application code all I get is empty COM objects.

I'm having trouble using python objects without leaking memory.

var baz = myModule.getNumber() as PyObject;
baz.As<int>(); // put this in a for loop and watch the memory explode
