Python 3.13.0rc1 : strange crash of Python running ...

... my windows 10 crash the python running ... this is the output of crash:

Python Qt6 : Dependency checker for python packages with pipdeptree and PyQt6.

Today I created this python script to test and check python package dependency.

You need to install the pipdeptree with the pip tool.

I used the Python 3.13.0rc1 version and the result is this:

This is the source code I used:

import sys
import subprocess
from PyQt6.QtWidgets import (
    QApplication, QMainWindow, QVBoxLayout, QTreeWidget, QTreeWidgetItem, QWidget
)
from PyQt6.QtWidgets import QHeaderView
from PyQt6.QtGui import QIcon

class DependencyViewer(QMainWindow):
    def __init__(self):
        super().__init__()

        self.setWindowTitle("Dependency Checker")

        # Maximizarea ferestrei la lansare
        self.showMaximized()

        # Creează un QTreeWidget pentru afișarea dependențelor
        self.tree_widget = QTreeWidget()
        self.tree_widget.setHeaderLabels(["Dependency", "Status"])

        # Ajustează aliniamentul central pentru fiecare coloană
        for i in range(2):  # Pentru cele două coloane
            self.tree_widget.headerItem().setTextAlignment(i, Qt.AlignmentFlag.AlignCenter)

        # Configurarea automată a lățimii coloanelor
        self.tree_widget.header().setSectionResizeMode(QHeaderView.ResizeMode.ResizeToContents)

        # Layout
        layout = QVBoxLayout()
        layout.addWidget(self.tree_widget)

        container = QWidget()
        container.setLayout(layout)
        self.setCentralWidget(container)

        # Obține și afișează dependențele
        self.display_dependencies()

    def display_dependencies(self):
        try:
            # Rulează pipdeptree pentru a obține ierarhia dependențelor
            result = subprocess.run(['pipdeptree', '--warn', 'silence'], capture_output=True, text=True)
            dependencies = result.stdout.splitlines()

            for line in dependencies:
                # Determină nivelul de indentare pentru ierarhia dependențelor
                indent_level = len(line) - len(line.lstrip())
                dependency_name = line.strip()

                # Creează un item pentru fiecare dependență
                item = QTreeWidgetItem([dependency_name])

                if "(*)" in dependency_name:  # Exemplu de incompatibilitate (poți schimba după caz)
                    item.setIcon(0, self.style().standardIcon(QStyle.StandardPixmap.SP_DialogCancelButton))
                    item.setText(1, "Incompatible")
                else:
                    item.setIcon(0, self.style().standardIcon(QStyle.StandardPixmap.SP_DialogApplyButton))
                    item.setText(1, "Compatible")

                # Adaugă item-ul în arbore
                if indent_level == 0:
                    self.tree_widget.addTopLevelItem(item)
                else:
                    # Alege ultimul item părinte și adaugă dependența ca sub-item
                    parent_item = self.tree_widget.topLevelItem(self.tree_widget.topLevelItemCount() - 1)
                    parent_item.addChild(item)

            # Extinde toate elementele din arbore
            self.tree_widget.expandAll()

        except Exception as e:
            error_item = QTreeWidgetItem(["Error", str(e)])
            error_item.setIcon(0, self.style().standardIcon(QStyle.StandardPixmap.SP_MessageBoxCritical))
            self.tree_widget.addTopLevelItem(error_item)


if __name__ == "__main__":

Python 3.13.0rc1 : testing the new Kivy-2.3.1 with default examples.

Today I tested the Kivy-2.3.1 with Python 3.13.0rc1.

Monday, March 10, 2025

News : Ollama-Adaptive-Image-Code-Gen project test - need more memory.

Python code that leverages a language model (such as LLaMA) to generate images featuring basic shapes in 2D or 3D. The script randomly selects shapes, colors, and areas to create diverse visuals. It continuously generates images based on AI-generated code, validates them, and provides feedback for iterative improvements.

This source code can be found on this GitHub project named Ollama-Adaptive-Image-Code-Gen.

You can download this and use these commands to run and test this feature of create and generate images with ollama.

NOTE: Compose up process might upto 20 - 25 Mins. first time. Because it will download all the respective ModelFiles

Python 3.13.0rc1 : Python script as window 10 service.

The main reason I tested this python issues comes from this:

I have a strange usage of msedgewebview2.exe on my window 10.

The right way was to install but I cannot do that because is not my laptop.

I created a python script to make logs and kill this process:

import win32serviceutil
import servicemanager
import win32event
import win32service
import time
import logging
import psutil

class MyService(win32serviceutil.ServiceFramework):
    _svc_name_ = 'catafestService'
    _svc_display_name_ = 'My catafest Service tool'

    def __init__(self, args):
        win32serviceutil.ServiceFramework.__init__(self, args)
        self.hWaitStop = win32event.CreateEvent(None, 0, 0, None)
        self.stop_requested = False
        logging.basicConfig(filename='D:\\PythonProjects\\catafest_services\\logfile.log', level=logging.DEBUG,
                            format='%(asctime)s - %(name)s - %(levelname)s - %(message)s')

    def SvcStop(self):
        self.ReportServiceStatus(win32service.SERVICE_STOP_PENDING)
        win32event.SetEvent(self.hWaitStop)
        self.stop_requested = True
        logging.info('Service stop requested')

    def SvcDoRun(self):
        servicemanager.LogMsg(servicemanager.EVENTLOG_INFORMATION_TYPE,
                              servicemanager.PYS_SERVICE_STARTED,
                              (self._svc_name_, ''))
        logging.info('Service started')
        self.main()

    def main(self):
        while not self.stop_requested:
            try:
                # Check and terminate 'msedgewebview2.exe' process
                for proc in psutil.process_iter(['pid', 'name']):
                    if proc.info['name'] == 'msedgewebview2.exe':
                        proc.kill()
                        logging.info(f'Terminated process: {proc.info["name"]} (PID: {proc.info["pid"]})')
                logging.info('Service running...')
                time.sleep(10)  # Runs every 10 seconds
            except Exception as e:
                logging.error(f'Error occurred: {e}', exc_info=True)
                servicemanager.LogMsg(servicemanager.EVENTLOG_ERROR_TYPE,
                                      servicemanager.PYS_SERVICE_STOPPED,
                                      (self._svc_name_, f'Error occurred: {e}'))
                break
        logging.info('Service stopped')

if __name__ == '__main__':
    win32serviceutil.HandleCommandLine(MyService)

You need to install pyinstaller to make a exe file:

pip install pyinstaller
...
Successfully installed altgraph-0.17.4 pefile-2023.2.7 pyinstaller-6.12.0 pyinstaller-hooks-contrib-2025.1
pywin32-ctypes-0.2.3

The next step install the pywin32 python package:

pip install pywin32

... try to make executable:

pyinstaller --onefile catafest_services.py

... use the start:

catafest_services.exe start
Traceback (most recent call last):
  ...
  File "win32serviceutil.py", line 706, in HandleCommandLine
  File "win32serviceutil.py", line 624, in GetServiceClassString
ModuleNotFoundError: No module named 'win32timezone'
[PYI-6880:ERROR] Failed to execute script 'catafest_services' due to unhandled exception!

... this error comes from interaction on running with windows services:

try to fix with this:

pyinstaller --name=catafest_services --onefile catafest_services.py

Open the generated spec file catafest_services.spec and add the win32timezone module to the hidden imports. See:

# -*- mode: python ; coding: utf-8 -*-
block_cipher = None

a = Analysis(['catafest_services.py'],
             pathex=['D:\\PythonProjects\\catafest_services'],
             binaries=[],
             datas=[],
             hiddenimports=['win32timezone'],
             hookspath=[],
             runtime_hooks=[],
             excludes=[],
             win_no_prefer_redirects=False,
             win_private_assemblies=False,
             cipher=block_cipher,
             noarchive=False)
             
# The rest of the file remains unchanged

Rebuild the executable using the modified spec file:

pyinstaller catafest_services.spec
709 INFO: PyInstaller: 6.12.0, contrib hooks: 2025.1
711 INFO: Python: 3.13.0rc1
791 INFO: Platform: Windows-10-10.0.19045-SP0
791 INFO: Python environment: C:\Python313
...

Try again with start:

catafest_services.exe start

I got this output:

catafest_services.exe start
Starting service catafestService 
Error starting service: Access is denied.

Open the command prompt as administrator and try again:

catafest_services.exe start
Starting service catafestService
Error starting service: The service did not respond to the start or control request in a timely fashion.

Same interaction because try to kill a process and more ...

This not work, but is another good way to use it by using the debug:

catafest_services.exe debug
Debugging service catafestService - press Ctrl+C to stop.
I n f o   0 x 4 0 0 0 1 0 0 2   -   T h e   c a t a f e s t S e r v i c e   s   r v i c e   h a s   s t a r t e d .
 Stopping debug service.

Under debug all works well, some msedgewebview2 processes are gone.

I stop this run and I try to work on development ...

Next step: If all works then you can use install:

catafest_services.exe install
Installing service catafestService
Service installed

You can do more. Make sure the account running the service has the necessary permissions. You can specify a user account during service installation:

catafest_services.exe install --username your_domain\your_username --password your_password

You can use this command to see these info:

set user

Last step: You can open the Services Manager by typing services.msc in the Windows Run dialog. Use press Win + R keys to open the Run dialog.

Manage the service as any services. You can use even on command prompt:

catafest_services.exe
Usage: 'catafest_services.exe [options] install|update|remove|start [...]|stop|restart [...]|debug [...]'t_services>cd dist
Options for 'install' and 'update' commands only:
 --username domain\username : The Username the service is to run under
 --password password : The password for the username
 --startup [manual|auto|disabled|delayed] : How the service starts, default = manual
 --interactive : Allow the service to interact with the desktop.
 --perfmonini file: .ini file to use for registering performance monitor data
 --perfmondll file: .dll file to use when querying the service for
   performance data, default = perfmondata.dll
Options for 'start' and 'stop' commands only:
 --wait seconds: Wait for the service to actually start or stop.
                 If you specify --wait with the 'stop' option, the service
                 and all dependent services will be stopped, each waiting
                 the specified period.

News : Python and Grok 3 Beta — The Age of Reasoning Agents

On the official website of x.ai you can find this:

We are thrilled to unveil an early preview of Grok 3, our most advanced model yet, blending superior reasoning with extensive pretraining knowledge.

You can find a simle and good example with python and pygame how this can be used.

The Grok 3 artificial inteligence is used for :

Research

Brainstorm

Analyze Data

Create images

Code

For me, the artificial intelligence help me to be more fast into coding versus issues and bugs, game design, parse and change data.

I don't test this Grok 3, but I can tell you some artificial inteligence into develop area are bad even they say is dedicated to this issue.

Python 3.13.0rc1 : Testing python with Ollama local install.

I was very busy with development and testing for about two weeks and my laptop was stuck and I was working hard... Today I managed to test local background clipping on my laptop with a local Ollama installation separated by a Python module but with processing from the Python script. I also used Microsoft's Copilot artificial intelligence for python and it works well even though it is not theoretically specialized in development. The source code is quite large but the result is very good and fast:

import subprocess
import os
import json
from PIL import Image, ImageOps

class OllamaProcessor:
    def __init__(self, config_file):
        self.config_file = config_file
        self.model_methods = self.load_config()

    def load_config(self):
        try:
            with open(self.config_file, 'r') as file:
                config = json.load(file)
            print("Configuration loaded successfully.")
            return config
        except FileNotFoundError:
            print(f"Configuration file {self.config_file} not found.")
            raise
        except json.JSONDecodeError:
            print(f"Error decoding JSON from the configuration file {self.config_file}.")
            raise

    def check_ollama(self):
        try:
            result = subprocess.run(["ollama", "--version"], capture_output=True, text=True, check=True)
            print("Ollama is installed. Version:", result.stdout)
        except subprocess.CalledProcessError as e:
            print("Ollama is not installed or not found in PATH. Ensure it's installed and accessible.")
            raise
...

Here is the result obtained after finishing running in the command line:

python ollama_test_001.py
Configuration file ollama_config.json created successfully.
Configuration loaded successfully.
Ollama is installed. Version: ollama version is 0.5.7

Blender 3D and python scripting - part 031.

This python script for blender will select vertrices based on boolean ...

This is the result with Blender version 4.3 :

This is the python script:

import bpy, bmesh

obj = bpy.context.active_object
me = obj.data

bpy.ops.object.mode_set(mode = 'EDIT') 
bpy.ops.mesh.select_mode(type="VERT")


bm = bmesh.from_edit_mesh(obj.data)
selected = [False,False,True,True,True,True,True,True]
verts = [vert for vert in bpy.context.active_object.data.vertices if vert.select]
all = [vert for vert in bpy.context.active_object.data.vertices]
print("selected:",len(verts))
print("all:",len(all))
bpy.ops.object.mode_set(mode = 'OBJECT')
me.vertices.foreach_set(
"select",
selected
)
bpy.ops.object.mode_set(mode = 'EDIT')

Blender 3D and python scripting - part 030.

Today I will show a python script for Blender 3D that create an 3D object and one material.

This is the final result of this python script:
