Description

Every time I start a new Android service I see a lot of annoying errors about blake2b. @T-Dynamos said he was responsible for this and it was introduced in python 3.11 and asked me to open this issue here.

Same problem here!

[Tear4Pixelation]

Same problem here with openai and pydantic package especially. The minimal reproducible example looks about as follows:

import os

import openai
from dotenv import load_dotenv
from kivy.lang import Builder
from kivymd.app import MDApp


class SampleApp(MDApp):
    
    def build(self):
        self.appKv='''
MDScreen:
    MDLabel:
        text:'Hello,World.'
        multiline:True
        color:"blue"
        halign:'center'         
'''
        AppScreen=Builder.load_string(self.appKv)
        return AppScreen

# Try to use openai
load_dotenv('project.env')
client = openai.OpenAI(api_key=os.getenv('OPENAIKEY'))
print(f"OpenAI client created: {client}")


SampleApp().run()

which crashes on start. (I use Android Studios emulator to run the apk)

[FilipeMarch]

@T-Dynamos any updates on this?

[T-Dynamos]

It will be fixed with support of python 3.13 PR (next to next planned PR).

Current status:

1. numpy fix #3164
2. python 3.13 (rework required) https://github.com/kivy/python-for-android/pull/3180
3. scipy #3136

[T-Dynamos]

@FilipeMarch you can test #3180 to check if the problem is resolved.

[Tear4Pixelation]

Welp I already rewrote the app in kotlin lol but still very nice to see there is still development on this

[T-Dynamos]

@Tear4Pixelation This issue wasn’t actually an error, it was just a warning. Your app might have been crashing for a different reason.

[Tear4Pixelation]

Well it was, in this case, an error. It seems pydantic was reliant on those algorithms. Because as soon as you tried to use the library (through openai), the app crashed with only that error. If I rewrote this script to only initialize openai at the press of a button, it would crash when the button is pressed with that error.

Same problem here with openai and pydantic package especially. The minimal reproducible example looks about as follows:

import os

import openai
from dotenv import load_dotenv
from kivy.lang import Builder
from kivymd.app import MDApp


class SampleApp(MDApp):
    
    def build(self):
        self.appKv='''
MDScreen:
    MDLabel:
        text:'Hello,World.'
        multiline:True
        color:"blue"
        halign:'center'         
'''
        AppScreen=Builder.load_string(self.appKv)
        return AppScreen

# Try to use openai
load_dotenv('project.env')
client = openai.OpenAI(api_key=os.getenv('OPENAIKEY'))
print(f"OpenAI client created: {client}")


SampleApp().run()

which crashes on start. (I use Android Studios emulator to run the apk)

[T-Dynamos]

This issue no longer exists in develop branch.
