Torch is not able to use GPU; add --skip-torch-cuda-test to COMMANDLINE_ARGS variable to disable this check
```
This is one of the most frequently mentioned problems, but it's usually not a WebUI fault, there are many reasons for it.
- WebUI uses GPU by default, so if you don't have suitable hardware, you need to [run on CPU](https://github.com/AUTOMATIC1111/stable-diffusion-webui/wiki/Command-Line-Arguments-and-Settings#running-on-cpu).
- WebUI uses GPU by default, and to make sure that GPU is working is working correctly we perform a test to see if CUDA is available, CUDA is only available on NVIDIA GPUs, so if you don't have a NVIDIA GPU or if the card is too old you might see this message.
- If you encountered this message with a Navidad graphics card, then something is wrong, then something has gone wrong and is preventing whether you are from using your GPU properly.
- However if you're using different Hardware such as an AMD GPU or a Mac then this message is expected, you should add `--skip-torch-cuda-test` to COMMANDLINE_ARGS as to bypass this CUDA test and follow the installation guide for you are specific hardware.
your specific hardware, and
if you don't have any hardware acceleration then the only option for you is to run on to [run on CPU](https://github.com/AUTOMATIC1111/stable-diffusion-webui/wiki/Command-Line-Arguments-and-Settings#running-on-cpu).
- Make sure you configure the WebUI correctly, refer to the corresponding installation tutorial in the [wiki](https://github.com/AUTOMATIC1111/stable-diffusion-webui/wiki).
- If you encounter this issue after some component updates, try undoing the most recent actions.
