1. Create an environment with Python 3.10
2. Pip install rembg

Expected behavior Successful pip install

Images Input images to reproduce.

OS Version: Mac OS Sonoma 14.6.1

Hi there,

Thank you for reporting the installation issue with rembg. It seems like you're encountering a problem while trying to install llvmlite, which is required for numba, in your environment.

Bug Description: When trying to install rembg using pip in a Python 3.10 environment, the installation fails with the following error messages:

FileNotFoundError: llvm-config not found. RuntimeError: llvm-config failed executing, indicating that the environment cannot locate the LLVM configuration. Steps to Reproduce:

Create a virtual environment with Python 3.10. Attempt to install rembg using pip install rembg. Environment Details:

OS Version: Mac OS Sonoma 14.6.1 Rembg Version: v2.0.59 Error Output: The error log indicates issues related to llvm-config, which is essential for building llvmlite. The specific error reads: RuntimeError: llvm-config failed executing, please point LLVM_CONFIG to the path for llvm-config

Install LLVM: Ensure that LLVM is installed on your system. You can install it using Homebrew: brew install llvm

Hello! This does not account for the fact though that it doesn't run on docker since I'm using the python3.10-slim image which is a debian image. Thanks though!

llvmlite requires at most llvm@10, but sonoma only has llvm@11 and above 😡

A variation on the same issue - that is the dependency on numba:

  help: `numba` (v0.53.1) was included because `rembg` (v2.0.60) depends on `pymatting` (v1.1.13) which depends
        on `numba`
