- if your version of Python is not in PATH (or if another version is), create or modify `webui.settings.bat` in the root folder (same place as webui.bat), add the line `set PYTHON=python` to say the full path to your python executable: `set PYTHON=B:\soft\Python310\python.exe`.

### What options to use for low VRAM videocards? ### What options to use for low VRAM video-cards?
Use command line options by creating or modifying `webui.settings.bat` in the root folder (same place as webui.bat), adding a line with `set COMMANDLINE_ARGS=`, and adding the settings at the end of that line. Use command line options by creating or modifying `webui.settings.bat` in the root folder (same place as webui.bat), adding a line with `set COMMANDLINE_ARGS=`, and adding the settings at the end of that line.
For example, `set COMMANDLINE_ARGS=--medvram --opt-split-attention`. You can, through command line arguments, enable the various optimizations which sacrifice some/a lot of speed in favor of using less VRAM. To do so, simply create (or modify it, if you've previously created it) a file called `webui.settings.bat` _in the same folder_ as `webui.bat`. Inside there should only be one line: `webui.bat <arguments>`
For example, `webui.bat --medvram --opt-split-attention`.
Here's a list of optimization arguments:
- If you have 4GB VRAM and want to make 512x512 (or maybe up to 640x640) images, use `--medvram`. - If you have 4GB VRAM and want to make 512x512 (or maybe up to 640x640) images, use `--medvram`.
- If you have 4GB VRAM and want to make 512x512 images, but you get an out of memory error with `--medvram`, use `--medvram --opt-split-attention` instead. - If you have 4GB VRAM and want to make 512x512 images, but you get an out of memory error with `--medvram`, use `--medvram --opt-split-attention` instead.

- If you have 4GB VRAM and want to make images larger than you can with `--medvram`, use `--lowvram --opt-split-attention`. - If you have 4GB VRAM and want to make images larger than you can with `--medvram`, use `--lowvram --opt-split-attention`.
- If you have more VRAM and want to make larger images than you can usually make, use `--medvram --opt-split-attention`. You can use `--lowvram` - If you have more VRAM and want to make larger images than you can usually make (for example 1024x1024 instead of 512x512), use `--medvram --opt-split-attention`. You can use `--lowvram`
