Python 3.13.0 : Script for python modules then installs them - updated with fix.

This script scans a folder full of .py files Python scripts, identifies all the external modules they import, filters out built-in ones, writes the installable ones to a requirements.txt file, and then installs them using pip—in parallel threads for speed.

I use the copilot and some comments are into my language, but I tested and works well:

NOTE: I updated with detection python modules based "from" and another issue: check if python module is instaled and step over that python module ...

This script will try to install many python modules, I can update to be better with these issues:

...some modules are default , some scripts are from another area, see Blender 3D with bpy python modules, some packages comes with same modules, this can be soleved with defined lists with unique items.

Python 3.13.0 : Predicted XAU/USD with torch.

Testing the torch python package

import torch
import torch.nn as nn

data = np.array([
    [1800.5, 1810.0, 1795.0, 1000, 1805.2],

Python 3.13.0 : Predicted XAU/USD with MLPRegressor.

Testing the MLPRegressor from sklearn python package:

from sklearn.neural_network import MLPRegressor
import numpy as np

print("Predicted XAU/USD closing price:", round(prediction[0], 2))

The answer is: Predicted XAU/USD closing price: 1836.68

PyQt6 : Use python with ffmpeg tool ...

If you download a video from youtube with high resolution using a tool as yt-dlp then you can get two files with video and audio content:

... one with be with .f401.mp4 and another with .f251-9.webm and using the ffmpeg tool you can create one .mp4 file with both audio and video content.

News : Django Hijack

Log in and work on behalf of other users without having to know their credentials.

With Django Hijack, admins can impersonate and work on behalf of other users without having to know their credentials.

Comes with two versions available: v2.x and v3.x. The last v3.x provides a security first design, easy integration, customisation, out-of-the-box Django admin support and dark-mode. It is a complete rewrite and all former APIs are broken.

See the webpage project.

News : The geoai-py - part 001.

A powerful Python package for integrating Artificial Intelligence with geospatial data analysis and visualization

GeoAI bridges the gap between AI and geospatial analysis, providing tools for processing, analyzing, and visualizing geospatial data using advanced machine learning techniques. Whether you're working with satellite imagery, LiDAR point clouds, or vector data, GeoAI offers intuitive interfaces to apply cutting-edge AI models.

Today , I tested this python package named geoai-py. I used the pip tool:

Python Qt6 : simple celtic knots tool with SVG file format.

Today, I try to create SVG file with an celtic knot design tool.

I used random values from -360 up to 360 for for Twist 1, Twist 2, and Twist 3 sliders.

The basic function is this, is created by artificial intelligence and not works very well.

        # Generate star polygon vertices
        points_cw = []
        points_ccw = []
        for i in range(steps):
            t = 2 * math.pi * i / steps
            r = outer_radius if i % 2 == 0 else inner_radius
            x_cw = center[0] + r * math.cos(t)
            y_cw = center[1] + r * math.sin(t)
            x_ccw = center[0] + r * math.cos(-t + math.pi / max(lobes, 1))
            y_ccw = center[1] + r * math.sin(-t + math.pi / max(lobes, 1))
            points_cw.append((x_cw, y_cw))
            points_ccw.append((x_ccw, y_ccw))

See one random example with this tool:

Python Qt6 : simple merge sprites images with unittest feature.

Today, I created one python tool script with the artificial intelligence to merge sprites images.

I used the artificial intelligence to add unittest to create default images with PIL to test the result.

You can select your folder , select the align of merge features or test with unittest button.

Python 3.13.5 : keras and torch and tensorflow on python version 3.13.5 !

I am not very satisfied with the security of the system in this area, I have noticed intrusions when I was at the Vodafone provider and now I am on mobile and they persist. I should improve my software and hardware protection and restart the system, but I have the impression that it won't help much considering the hacking capabilities that exist.

For now, I'm sticking with this solution, because it's quite good for simple tests with the Python language.

Today I will show you that the involvement of developers is somewhat lagging behind, and this can be seen from the analysis of the development progression across versions of the Python language, as it is not easy to implement in newer versions. Some packages, although important, are not available in newer versions.Today I will show you that the involvement of developers is somewhat lagging behind, and this can be seen from the analysis of the development progression across versions of the Python language, as it is not easy to implement in newer versions. Some packages, although important, are not available in newer versions. Let's see these python packages:

Keras is a deep learning API designed for human beings, not machines. Keras focuses on debugging speed, code elegance & conciseness, maintainability, and deployability. When you choose Keras, your codebase is smaller, more readable, easier to iterate on.

TensorFlow does not support Python 3.13 as of July 2025; it supports Python 3.9–3.11. To use Keras with TensorFlow, downgrade to Python 3.11, and this install will comes with:

pip install tensorflow

Python 3.13.5 : the groq tested with basic example !

About groq you can find on the official Grok website .

Today I tested the groq A.P.I. with the basic example :

import os

from groq import Groq

client = Groq(
    api_key="gsk_..."
)

chat_completion = client.chat.completions.create(
    messages=[
        {
            "role": "user",
            "content": "explain what groq is",
        }
    ],
    model="llama-3.3-70b-versatile",
)

print(chat_completion.choices[0].message.content)

The result of : "explain what groq is" is that :

Groq is a relatively new and innovative technology company that focuses on developing high-performance, artificial intelligence (AI) computing hardware and software solutions.
