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

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

Python 3.13.0 : Only the unstructured library in Fedora 41 ...

The unstructured library provides open-source components for ingesting and pre-processing images and text documents, such as PDFs, HTML, Word docs, and many more. The use cases of unstructured revolve around streamlining and optimizing the data processing workflow for LLMs. unstructured modular functions and connectors form a cohesive system that simplifies data ingestion and pre-processing, making it adaptable to different platforms and efficient in transforming unstructured data into structured outputs.

I used pip tool to install this python package:

mythcat@fedora:~$ pip install unstructured

News : Colab behavior through runtime .

I would like Google to emphasize more on the development side some elements that work like robots by interfacing with the development side.

Today I worked a little on artificial intelligence and I realized that it doesn't create textgenrnn_weights.hdf5 file for training created with the Python textgenrnn mode.

A solution is to reset the runtime with Ctrl+M and resume running.

They specify RESTART RUNTIME when using Python modules, see:

WARNING: The following packages were previously imported in this runtime:
   [numpy]
You must restart the runtime in order to use newly installed versions.

In this case, with the creation of textgenrnn_weights.hdf5 file, it is more difficult to understand and cannot be seen easily.

Python : Fix error user on install with requirements.txt.

The error show like this :

ERROR: Could not install packages due to an OSError: [WinError 5] Access is denied: 'C:\\Python311\\share'
Consider using the `--user` option or check the permissions.

This can be easy fix with :

pip install -r requirements.txt --user

By using the --user flag, the packages will be installed in the user-specific site-packages directory, ensuring that the packages are installed only for the current user and not affecting the system-wide Python installation.

Python : Fix error with pip and pylupdate6.exe .

I try to upgrade the PyQt6 package and I got this error:

pip3 install --upgrade --force-reinstall PyQt6
...
ERROR: Could not install packages due to an OSError: [WinError 2] The system cannot find the file specified:
...pylupdate6.exe
...pylupdate6.exe.deleteme'

I think this solution will work for any python package

Open a command shell run as administrator and run it again:

pip3 install --upgrade --force-reinstall PyQt6
Collecting PyQt6
...
Successfully installed PyQt6-6.4.1 PyQt6-Qt6-6.4.2 PyQt6-sip-13.4.1

If you want to re-download the packages instead of using the files from your pip cache, then use:

pip install --force-reinstall --no-cache-dir

Python : Fix DLL load failed while importing ...

This error DLL load failed while importing ... can have many causes like conflicts with the already installed packages, and also it can break your current environment.

>>> import PyQt6
>>> from PyQt6.QtCore import QUrl
Traceback (most recent call last):
  ...
ImportError: DLL load failed while importing QtCore: The specified module could not be found.

You can see I used to reinstall the PyQt6 python package with this argument --ignore-installed:

pip3 install PyQt6 --user --ignore-installed
Collecting PyQt6
  ...
Installing collected packages: PyQt6-Qt6, PyQt6-sip, PyQt6
  WARNING: The scripts pylupdate6.exe and pyuic6.exe are installed in

  Consider adding this directory to PATH or, if you prefer to suppress this warning, use --no-warn-script-location.
Successfully installed PyQt6-6.4.0 PyQt6-Qt6-6.4.2 PyQt6-sip-13.4.0

The --ignore-installed option for the pip package manager was first introduced in version 6.0, which was released in April 2014.

The old install give me this error and when I try to use I got this:

>>> from PyQt6 import *
>>> dir(PyQt6)
['__builtins__', '__cached__', '__doc__', '__file__', '__loader__', '__name__', '__package__', '__path__', '__spec__']

Now after I reinstall with this option the result is good:

>>> import PyQt6
>>> from PyQt6 import QtCore
>>> dir(PyQt6)
['QtCore', '__builtins__', '__cached__', '__doc__', '__file__', '__loader__', '__name__', '__package__', '__path__', '__spec__', 'sip']
>>> from PyQt6.QtCore import QUrl

Python Qt6 : The basic differences between PyQt5 and PyQt6.

Python Qt6 known as PyQt6 is a binding of the cross-platform GUI toolkit Qt, implemented as a Python plug-in with Qt 6 the latest version of Qt.

The PyQt6 first stable release was on 6 January 2021, developed by Riverbank Computing Ltd and the last release was on 2 December 2021 with the version PyQt v6.2.2.

This release is license GPL or commercial on Python 3 platform.

Let's see some differences between PyQt5 and PyQt6.

The .exec() method is used in Qt to start the event loop of your QApplication or dialog boxes. In Python 2.7 exec was a keyword and Python 3 removed the exec keyword.

The first difference as a result of PyQt6 .exec() calls are named just as in Qt.

If you read the documentation from the official webpage, then in your PyQt6 source code you need to use these changes:

QEvent.Type.MouseButtonPress
...
Qt.MouseButtons.RightButton
...

Both PyQt5 and PyQt6, although seemingly easy to use for complex applications, will require extra effort.

Python Qt5 : PyQt5 and PyGame compatibility with source code.

This tutorial tries to solve from the objectives related to solving and stabilizing compatibility errors between PyQt4 and PyQt5 and creating a common interface between PyQt5 and PyGame.

There is always the same problem in programming when the developer for some reason has to change classes, methods and functions and reusing the old code is no longer valid.

In this case, common or other errors occur, which leads to a waste of time.

I will present a simple way to solve these problems.

I really like to use the PyQt5 module to create interfaces for my python programs and scripts.

Like any programmer who hasn't fully used all A.P.I, I always use the old source code I programmed in the past.

What the developer says about the transition from PyQt4 to PyQt5 we can see on the official page.

Obviously, you will have to move on to things to know but it is quite difficult to always come back and read this content when you have programming errors.

Today, I wanted to make a simple drawing interface in PyGame that would be included in a PyQt5 interface.

I tried to use an old code created by me in PyQt4 but I realized that I had encountered errors before switching to the new PyQt5.

This compatibility problem generates errors and can be solved as follows: by knowing the exact solution and fixing errors in real time, studying the changes created by the developer or the classic search for errors.

My solution comes with the help of these solutions and requires a simple step using the commented source code.

To show you how simple it is to understand I will show you the source code for the interface I built that simply to solves the problem of understanding compatibility by reading the developer source code with simple and useful comments.

Install , test and fix error of the jupyter-book into python 3.

Jupyter Books lets you build an online book using a collection of Jupyter Notebooks and Markdown files. Its output is similar to the excellent Bookdown tool, and adds extra functionality for people running a Jupyter stack.
Read more about this on the official webpage.
Today I start to test this python module named jupyter-book.
I find some errors and I fixed to running well a demo jupyter-book instance.

The reason is the python 3.x and can be fixed by change the encoding into this file:
c:\python364\lib\site-packages\jupyter_book\build.py with this:

with open(path_new_file, 'r',encoding='utf-8') as ff:

The next step is to build the catafest jupyter-book:

C:\Python364>jupyter-book build catafest
Convert and copy notebook/md files...
... 

My GitHub account is catafest and I used this link to create a new repo named catafest_jupyter-book:

Fix errors when write files.

The python is a very versatile programming language.
The tutorial for today is about:

• check the type of variables;
• see the list error of writelines with the list output;
• fix errors for writelines;

One good example for some errors can be this:

>>> file.writelines(paragraphs)
Traceback (most recent call last):
  File "", line 1, in 
TypeError: a bytes-like object is required, not 'str'
>>> file.writelines(paragraphs.decode('utf-8'))
Traceback (most recent call last):
  File "", line 1, in 
AttributeError: 'list' object has no attribute 'decode'

Is a common issue for list and writing file.
The result of paragraphs is a list, see:

>>> type(paragraphs)

The list can be write with te writelines into the file like this:

>>> file = open("out.txt","wb")
>>> file.writelines([word.encode('utf-8') for word in paragraphs])

The file is a open file variable and the paragraphs is a list.

Now you need to install this filter from here.
If not, you can get errors like this: raise NoBackendError('No backend available')
usb.core.NoBackendError: No backend available
Let's make a simple test example:

import usb.core
import usb.util
import sys

class find_class(object):
    def __init__(self, class_):
        self._class = class_
    def __call__(self, device):
        # first, let's check the device
        if device.bDeviceClass == self._class:
            return True
        # ok, transverse all devices to find an
        # interface that matches our class
        for cfg in device:
            # find_descriptor: what's it?
            intf = usb.util.find_descriptor(
                                        cfg,
                                        bInterfaceClass=self._class
                                )
            if intf is not None:
                return True

        return False

all = usb.core.find(find_all=1, custom_match=find_class(7))
print (all)

And show the result:

Fix PyCharm error install python module from conda .

Today I fix an error about PyCharm and conda.
As you know :
Conda is an open source package management system and environmental management system that runs on Windows, macOS and Linux.
Also, Conda quickly installs, runs and updates packages dependency and environment management for any language—Python, R, Ruby, Lua, Scala, Java, JavaScript, C/ C++, FORTRAN.
This error is from PyCharm install python modules using error check from PyCharm (Alt+Enter keys):

The result of this install come with this error from conda :

Close your PyCharm and use this command into your shell-like administrator:

C:\WINDOWS\system32>conda config --show
C:\WINDOWS\system32>conda config --set force True
C:\WINDOWS\system32>conda update conda

This command installs anaconda and updates it using my account catafest .
Start the I.D.E. PyCharm and after indexing all you can try to fix the python install module (Alt+Enter keys).
If the python modules are not into conda repo from PyCharm then you can use this command:

C:\WINDOWS\system32>conda install -c conda-forge opencv

In this example I used OpenCV python module named into python script like cv2, see the next image:

The python modules pygobject, pycairo and pygtk under Windows OS.

I used the python version 2.7 32 bits under .
C:\Python27>python

Intel)] on win32
Type "help", "copyright", "credits" or "license" for more information.
The issue is to instal PyGTK python module but you can see I got errors.
C:\>cd Python27

I install this python modules using registry and this option: Python from another location and I set my python path: C:\Python27\
>>> import gobject
>>> dir(gobject)

As you can see this python modules works well.

The python dizzy with clean instalation, is true !?

This will refer the python 2.7 working - but it can be extrapolated to other versions.
Many users have trouble installing python modules. The problem comes from old modules outdated or those who did not support.
I will present a few examples. I hope to come and support as necessary to remedy in time or exclusion through better solutions.
This is the main question for today: The python dizzy with clean instalation, is true !?
I don't think is a unwanted hacking of my python instalation using internet.
But I search and I saw many questions and erros over pip and Scripts folders.
I will deal just for this issue:
After I make one clean python 2.7 and all my python modules works well I used my windows to deal with some ssh software.
The next step I make it with python was to try to update with pip.
The strange think is with this files from Scripts folders:

12-Aug-16 06:41 PM 98,150 pyrsa-decrypt-bigfile.exe
12-Aug-16 06:41 PM 98,134 pyrsa-decrypt.exe
12-Aug-16 06:41 PM 98,150 pyrsa-encrypt-bigfile.exe
12-Aug-16 06:41 PM 98,134 pyrsa-encrypt.exe
12-Aug-16 06:41 PM 98,132 pyrsa-keygen.exe
12-Aug-16 06:41 PM 98,155 pyrsa-priv2pub.exe
12-Aug-16 06:41 PM 98,128 pyrsa-sign.exe
12-Aug-16 06:41 PM 98,132 pyrsa-verify.exe

and this file from same Script folder:

21-Jun-16 09:09 PM 0 python.exe

When I need to use pip I got errors.Then I try to fix with this:

pip install --upgrade ndg-httpsclient

and seem to be working now.
But I need to find from where come this file and why is this python file with:

C:\Python27\Scripts>python
Access is denied.

Maybe will be fix with a clean python instalation.
But the next step is and one of my concern is how to preserve this python instalation.
For example today the

pip update issue

come with many errors and this will be fixed.
Let's see how I fixed some of this.

First download Microsoft Visual C++ Compiler for Python 2.7.
This will fix this error:

error: Microsoft Visual C++ 9.0 is required. Get it from http://aka.ms/vcpython27

.

If you got this error: RuntimeError: Freetype library not found

C:\Python27>Scripts\pip install freetype-py

100% |################################| 399kB 758kB/s
Building wheels for collected packages: freetype-py
Running setup.py bdist_wheel for freetype-py ... done

You can see also this freetype-py will not working:

C:\Python27>python.exe

from freetype.raw import *
File "C:\Python27\lib\site-packages\freetype\raw.py", line 37, in
raise RuntimeError('Freetype library not found')
RuntimeError: Freetype library not found

Also some python module has into cloud dizzy stuff.
For example the pycryptodome come with many features and working great.
Also some alternative is a bad solution.
It is hard to find a solution to the problem of leaving all these modules.
Any solutions?

The numpy - install over python 3.4 version.

The last version 1.9.2 of python module can solve instalation over python from sourceforge.net -projects.
This link from Numerical Python module come with exe file over python versions: 3.4 , 3.3 and 2.7.
I test the 3.4 version - 32 bits but I got this great error:

>>> import numpy
Traceback (most recent call last):
File "", line 1, in 
File "C:\Python34\lib\site-packages\numpy\__init__.py", line 170, in 
from . import add_newdocs
File "C:\Python34\lib\site-packages\numpy\add_newdocs.py", line 13, in

File "C:\Python34\lib\site-packages\numpy\core\__init__.py", line 6, in 
from . import multiarray
ImportError: DLL load failed: %1 is not a valid Win32 application.

How to fix this:
Also the pip3.4 don't want to install the numpy python module just if you use this link.
You can do this with :

C:\Python34\Scripts>pip3.4.exe install --upgrade wheel
Requirement already up-to-date: wheel in c:\python34\lib\site-packages
C:\Python34\Scripts>pip3.4.exe install "C:\Users\...\Downloads\numpy-1.9.2+m
kl-cp34-none-win_amd64.whl"
After that you can import the numpy module 

How to fix error: fatal error: Python.h: No such file or directory

This is a common error when your system don't have the python-dev.

I got this error when I try to use : pip .

Just install the package python-dev and then all will working well.
