```

System:
- Mac M4, 128GB. Sequoia 15.5.

Start with requirements.txt and reproduce the reported pip install -r requirements.txt failure in a Python 3.10 conda environment on macOS arm64. Check how the pinned decord==0.6.0 dependency is handled for this platform; done means the documented environment setup can install the requirements successfully on the reported system.
