Hey there, this issue almost always comes down to mismatched Python environments—the environment where you installed Kivy via Anaconda isn’t the same one you’re using to run your code. Let’s fix this step by step:

1. Confirm Your Python Environment Match #

First, let’s check which Python has Kivy installed, and which one your code is running on:

• Open the Anaconda Prompt where you installed Kivy, then run these commands:

  # Check Python version
  python --version
  # Find Python executable path (Windows)
  where python
  # For macOS/Linux
  which python
  

• Now open the terminal/editor you’re using to run your code (like VS Code’s terminal or system CMD) and run the same commands. If the version or path doesn’t line up, you’re using separate environments.

2. Run Your Script in the Correct Anaconda Environment #

If you’re using an Anaconda virtual environment, activate it first before running your code:

# Replace "your_env_name" with your actual environment (e.g., base)
conda activate your_env_name
# Now run your script
python d:/Work/Porjects/Face Detector/appk.py

If you installed Kivy in the default base environment, just use the Anaconda Prompt directly to execute the run command above.

3. Point Your IDE to the Anaconda Python Interpreter #

If you’re using an editor like VS Code or PyCharm, make sure it’s using the Anaconda Python that has Kivy:

• VS Code: Click the Python version number in the bottom-left corner, then select the Anaconda Python path (e.g., C:\Users\YourName\anaconda3\python.exe or your virtual environment’s Python executable).
• PyCharm: Go to File > Settings > Project: [Your Project Name] > Python Interpreter, click the gear icon, select Add, then navigate to your Anaconda Python path and select it.

4. Verify Kivy is Installed in the Target Environment #

To double-check Kivy is present in the environment you’re using:
Activate the environment in Anaconda Prompt, then run:

# Check with pip (Windows)
pip list | findstr kivy
# For macOS/Linux
pip list | grep kivy
# Or check with conda
conda list kivy

You should see Kivy listed with a version number if it’s installed correctly.

Your Code for Reference #

import kivy
from kivy.app import App
from kivy.uix.label import Label

class MyApp(App):
    def build(self):
        return Label(text="hello")

if __name__ == "__main__":
    MyApp().run()

Error Snippet #

Traceback (most recent call last):
File "d:/Work/Porjects/Face Detector/appk.py", line 1, in
import kivy
ModuleNotFoundError: No module named 'kivy'
