Hi guys i have a problem with my c# - python code!
There's python code 
//python code 
def ImageAnalyze(filePath):
    import os
    from tensorflow.keras.models import load_model
    from PIL import Image
    import numpy as np
    model = load_model('D:\\VisualStudio\\RoadSignImageAnalyzer\\bin\\Debug\\net8.0-windows\\traffic_classifier.keras', compile = False)
    if os.path.exists('D:\\VisualStudio\\RoadSignImageAnalyzer\\bin\\Debug\\net8.0-windows\\traffic_classifier.keras') is False:
        return "Keras not found"
    def preprocess_image(image_path):
        try:
            image = Image.open(image_path)
            image = image.resize((30, 30))
            image = np.array(image)

            image = np.expand_dims(image, axis=0)  
            return image
        except Exception as e:
            print(f"Error processing image: {e}")
            return None
    processed_image = preprocess_image('D:\\VisualStudio\\RoadSignImageAnalyzer\\bin\\Debug\\net8.0-windows\\12630.png')
    if os.path.exists('D:\\VisualStudio\\RoadSignImageAnalyzer\\bin\\Debug\\net8.0-windows\\12630.png') is False:
        return "Phott not found"
    if processed_image is not None:
        prediction = model.predict(processed_image)
        predicted_class = np.argmax(prediction, axis=1)[0]
        message = f"Predicted Class: {predicted_class}"
        return message
    else:
        return "Error: Unable to process image" 
//python code 
def ImageAnalyze(filePath):
    import os
    from tensorflow.keras.models import load_model
    from PIL import Image
    import numpy as np
    model = load_model('D:\\VisualStudio\\RoadSignImageAnalyzer\\bin\\Debug\\net8.0-windows\\traffic_classifier.keras', compile = False)
    if os.path.exists('D:\\VisualStudio\\RoadSignImageAnalyzer\\bin\\Debug\\net8.0-windows\\traffic_classifier.keras') is False:

            image = image.resize((30, 30))
            image = np.array(image)

            image = np.expand_dims(image, axis=0)  
            return image
        except Exception as e:
            print(f"Error processing image: {e}")
            return None
    processed_image = preprocess_image('D:\\VisualStudio\\RoadSignImageAnalyzer\\bin\\Debug\\net8.0-windows\\12630.png')
    if os.path.exists('D:\\VisualStudio\\RoadSignImageAnalyzer\\bin\\Debug\\net8.0-windows\\12630.png') is False:
        return "Phott not found"
    if processed_image is not None:
        prediction = model.predict(processed_image)
        predicted_class = np.argmax(prediction, axis=1)[0]
        message = f"Predicted Class: {predicted_class}"
        return message
    else:
        return "Error: Unable to process image"
it works well. libraries also imports well(i checked the possibility to return every library version as string from that method so libraries is not a problem. Also filepath is fine and kernel trained model is fine too. This code works in another solution or in vs code jupiter notebook or even from my desctop in cmd/ But when i start it from c# it stops on that line 
 prediction = model.predict(processed_image) 
 prediction = model.predict(processed_image)
and then i heave this kind of exception Python.Runtime.PythonException: ''NoneType' object has no attribute 'write''

        string message = script.ImageAnalyze("D:\\VisualStudio\\PythonApplication1\\12630.png"); // dont look at the path its not used and its just a plug for function

        MessageBox.Show(message);
    }
}

        MessageBox.Show(message);
    }
}
Its c# code that needs to get just a string from my python code. I'm using pythonnet here for that.
