Wie kann ich Protobuf zu CMAKE hinzufügen?

Ich möchte die Bibliothek 'super-gradients' in Python über den Befehl

pip3 install super-gradients==2.0.0

installieren und erhalte einen Cmake Fehler, bei dem das Google Protobuf Paket fehlt. Hierzu diese Fehlermeldung:

-- Found PythonLibs: C:/Users/test/AppData/Local/Programs/Python/Python311/libs/python311.lib (found suitable version "3.11.5", minimum required is "3.11")

CMake Error at F:/Visual Studio 2022 Community/Common7/IDE/CommonExtensions/Microsoft/CMake/CMake/share/cmake-3.27/Modules/FindPackageHandleStandardArgs.cmake:230 (message):

Could NOT find Protobuf (missing: Protobuf_LIBRARIES Protobuf_INCLUDE_DIR)

Wie kann ich das beheben?

Das ist offenbar auf Windows, wo alles etwas mühsamer ist.

Du musst dir 1) selber die Library runterladen und 2) irgendwo entpacken, wo sie CMake findet.

ad 1)

https://github.com/protocolbuffers/protobuf/releases/

Es wird in deinem Fall wohl die win64-Distribution sein.

ad 2)

Auf Windows gibt es keine klar definierten "Standardorte" für Libraries, daher ist das mit dem "wo CMake sie findet" nicht ganz so klar. Ich würd's einfach mal im aktuellen Verzeichnis auspacken und probieren, ob es dort gefunden wird. Ansonsten kannst du https://cmake.org/cmake/help/latest/command/find_package.html durchackern.

Python Fehler bei Multiprocessing?

Hallo,

Momentan schreibe ich eine kleine Anwendung die Text sprechen soll. Mein Code:

Voice.py

from loguru import logger

class Voice():


    def __init__(self):
        import YAML

        p = multiprocessing.Process(target=self.__speak__, args=(text, ))

Python - tkinter text eingabe in variable?

Hallo,

ich habe folgendes programmiert:

import tkinter as tk
import os


root = tk.Tk()
root.geometry("400x240")


def encrypt(filename):
    to_encrypt = open(filename, "rb").read()
    size = len(to_encrypt)
    key = os.urandom(size)
    with open(filename + ".lqk", "wb") as key_out:
        key_out.write(key)
    encrypted = bytes(a ^ b for (a, b) in zip(to_encrypt, key))
    with open(filename, "wb") as encrypted_out:
        encrypted_out.write(encrypted)  
    filename = textExample.get(1.0, tk.END+"-1c")
    encrypt(filename)




def decrypt(filename, key):
    file = open(filename, "rb").read()
    key = open(key, "rb").read()
    decrypted = bytes(a ^ b for (a, b) in zip(file, key))
    with open(filename, "wb") as decrypted_out:
        decrypted_out.write(decrypted)
    fileTest = filename + ".lqk"
    try:
        os.remove(fileTest)
    except OSError as e:
        print(e)
    else:
        print("Datei erfolgreich gelöscht!")
    filename = textExample.get(1.0, tk.END+"-1c")
    decrypt(filename, filename + ".lqk")
    
    


textExample=tk.Text(root, height=10)
textExample.pack()
btnEncrypt=tk.Button(root, height=1, width=10, text="Encrypt", 
                    command=encrypt)
btnDecrypt=tk.Button(root, height=1, width=10, text="Decrypt", 
                    command=decrypt)


btnEncrypt.pack()
btnDecrypt.pack()


root.mainloop()

Nur leider funktioniert dies nicht. In der Debugging Console bekomme ich folgende Fehlermeldung:

Bei der Encrypt Funktion:

Wie kann man im Qt Designer den Code einfach zu Python umwandeln?

Hallo.

Also ich brauche Hilfe. Ich würde gern Windows Forms über Python statt mit C# programmieren, weil Python kann bis unendlich viel rechnen als C# und daraus möchte ich einen super Taschenrechner programmieren.

Ich verwende den Qt Designer und versuche denn Code umzuwandeln. Ich habe im Internet geschaut und diesen Code eingegeben:

from PyQt5 import uic, QtWidgets
import sys
 
class Ui(QtWidgets.QDialog):
    def __init__(self):
        super(Ui, self).__init__()
        uic.loadUi('Test.ui', self)
        self.show()
 
if __name__ == '__main__':
    app = QtWidgets.QApplication(sys.argv)
    window = Ui()
    sys.exit(app.exec_())

Ja und wenn ich das dann ausführe, spuckt er diese Fehlermeldung aus:

Traceback (most recent call last):
  File "C:/Users/PrinzPersia/Documents/Test.py", line 12, in <module>
    window = Ui()
  File "C:/Users/PrinzPersia/Documents/Test.py", line 7, in __init__
    uic.loadUi('Test.ui', self)
  File "C:\Users\PrinzPersia\AppData\Local\Programs\Python\Python35-32\lib\site-packages\PyQt5\uic__init__.py", line 226, in loadUi
    return DynamicUILoader(package).loadUi(uifile, baseinstance, resource_suffix)
  File "C:\Users\PrinzPersia\AppData\Local\Programs\Python\Python35-32\lib\site-packages\PyQt5\uic\Loader\loader.py", line 72, in loadUi
    return self.parse(filename, resource_suffix, basedir)
  File "C:\Users\PrinzPersia\AppData\Local\Programs\Python\Python35-32\lib\site-packages\PyQt5\uic\uiparser.py", line 992, in parse
    document = parse(filename)
  File "C:\Users\PrinzPersia\AppData\Local\Programs\Python\Python35-32\lib\xml\etree\ElementTree.py", line 1183, in parse
    tree.parse(source, parser)

    source = open(source, "rb")
FileNotFoundError: [Errno 2] No such file or directory: 'Test.ui'

Wisst ihr, woran es liegt? Ich kenne mich im Qt Designer gar nicht gut aus und Videotutorials anschauen ist wegen der niedrigen Bildschirmauflösung sehr anstrengend.

Kann mir jemand sagen was an dieser Zeile falsch ist?

WARNING: You are using pip version 21.1.3; however, version 24.0 is available.

You should consider upgrading via the 'D:\Python\python.exe -m pip install --upgrade pip' command.

Via cmd erhalte ich die gleiche Meldung.
Ich habe alle Python-Versionen schon deinstalliert, System neu gestartet und wieder installiert. Das gleiche habe ich auch mit pip probiert.

Kann mir hier vielleicht jemand weiterhelfen?

Vielen Dank und liebe Grüße im Voraus! :)

Shared library Nutzung in python "undefined symbol"?

Ich versuche ein möglichst einfaches Beispiel zu verwenden um überhaupt erstmal irgendwas zum Laufen zu bringen. Ich möchte die Funktionen einer shared library in python nutzen:

Calc.h

#ifndef CALC_H
#define CALC_H

class Calc {
public:
   int add();
};

#endif

Calc.cpp

#include "include/Calc.h"
int Calc::add() {
   return 5;
}

CMakeLists.txt

cmake_minimum_required(VERSION 3.0)

project(calc)

set(CMAKE_CXX_STANDARD 11)

# Define sources and executable
set(SOURCES Calc.cpp)

add_library(calc SHARED ${SOURCES})
target_link_libraries(calc ${LIBS} -Wl,--export-dynamic)

install(TARGETS calc DESTINATION lib)
install(FILES Calc.h DESTINATION include)

mkdir build && cd build && cmake .. && make

...
[100%] Linking CXX shared library libcalc.so
[100%] Built target calc

main.py

import ctypes

lib = ctypes.CDLL('./libcalc.so')

lib.add.restype = ctypes.c_int

result = lib.add()

print(result)
...$ python3 main.py 
Traceback (most recent call last):
 File ".../main.py", line 7, in <module>
   lib.add.restype = ctypes.c_int
 File "/usr/local/lib/python3.9/ctypes/__init__.py", line 387, in __getattr__
   func = self.__getitem__(name)
 File "/usr/local/lib/python3.9/ctypes/__init__.py", line 392, in __getitem__
   func = self._FuncPtr((name_or_ordinal, self))
AttributeError: ./libcalc.so: undefined symbol: add   <----------

Was mache ich falsch?

DOCKER Fehlermeldung: TypeError: function() argument 'code' must be code, not str, was tun?

Hallo, ich mit einem YouTube video eine kleine FastApi App geschrieben. Dann habe ich sie als ein Docker gebaut. Wenn ich diesen nun starte bekomme ich die im Titel stehende Fehlermeldung. `Ich habe schon ganz Google nach einer Möglichkeit durchgesucht aber leider keine Lösung gefunden. Vll. hat ja einer von euch 'ne Idee.

DER CODE:

from fastapi import FastAPI
from app.model.test import Upscale

app = FastAPI()

class TextIn(Upscale):
    org_url: str


class TextOut(Upscale):
    url: str



@app.get("/")
def home():
    return {"health_check": "OK"}

@app.post("/post", response_model=TextOut)
def UpSc(payload: TextIn):
    textwrap = Upscale(payload.org_url)
    return {"url": "url"}

KOMPLETTER TRACEBACK: `

in meinen requirements.txt steht:

fastapi
boto3
opencv-contrib-python-headless
opencv-python-headless
numpy

ich nutzte Python 3.9 habe es aber auch ohne Erfolg mit anderen Version probiert.
