Getting requirements to build wheel did not run successfully

[N4nn0x]

Running Python 3.12.5, trying to install requirements for YOLOv7 getting the below error (it goes on for longer). Are there any compatibility issues between these 2? should I try an earlier version of python?

py -m pip install -r requirements.txt

Collecting matplotlib>=3.2.2 (from -r requirements.txt (line 4))

Hi N4nn0x,

I encountered a similar issue while installing the requirements for YOLOv7 with Python 3.12.5. Here’s a potential solution that worked for me:

1. Switch to a Compatible Python Version: YOLOv7 and some of its dependencies may not be fully compatible with Python 3.12.5. I recommend using Python 3.10 or 3.11 as this repository was authored a couple of years ago. You can create a virtual environment with one of these versions:

   # Install Python 3.10 or 3.11
   py -m venv venv
   venv\Scripts\activate  # On Windows
   source venv/bin/activate  # On macOS/Linux
   
   # Then install the requirements
   py -m pip install -r requirements.txt

2. Upgrade Pip and Setuptools: Ensure you are using the latest versions of pip and setuptools to avoid any compatibility issues with building packages:

   py -m pip install --upgrade pip setuptools

3. Install Numpy Separately: Try installing numpy separately to handle potential build issues:

   py -m pip install numpy==1.23.5

4. Use Pre-built Wheels: If you continue to experience issues, consider using pre-built wheels for numpy to avoid building from source. You can find them on PyPI or Unofficial Windows Binaries for Python Extension Packages.

By following these steps, you should be able to resolve the installation issue. If anyone has further suggestions or different experiences, please share!

Thanks!
