What this teaches

How to assertionError: Torch not compiled with CUDA enabled - macOS Sequoia 15.1.1 (intel, AMD).

The problem

Issue Tencent-Hunyuan/HunyuanVideo#22 (closed, 8 comments): I'm encountering the following error while running the preprocesstextencodertokenizer function in the preprocesstextencodertokenizer_utils.py Environment: > Processor: Model: Intel(R) Xeon(R) W-2140B CPU Speed: 3.20 GHz Cores: 8 cores (with Hyper-Threading enabled) > Memory (RAM): Total RAM: 32 GB (34359738368 bytes) > GPU: Model: Radeon Pro Vega 56 VRAM: 8 GB Bus: PCIe (x16) Metal Support: Metal 3 (supports Apple's graphics framework) Expected Behaviour The model should successfully move to the device without raising the AssertionError. It would be helpful if PyTorch

What worked (verified answer)

The 'Torch not compiled with CUDA enabled' error is fixed by reinstalling the CUDA build of torch 2.1.1: python -m pip uninstall torch then python -m pip install torch==2.1.1 --index-url https://download.pytorch.org/whl/cu121.
