# Extras Install Common Problems

This page lists common questions and problems encountered while installing SillyTavern Extras.

Local installation of Extras can be difficult or impossible on your OS (especially Termux).

Could not connect to remote SD backend at http://127.0.0.1:7860! Disabling SD module...

Make sure webui-user.bat that you start Stable Diffusion with contains --api command line option in the COMMANDLINE_ARGS variable.

Find and replace that line in your "webui-user.bat": set COMMANDLINE_ARGS=--api

If the API mode is disabled for SD Web UI, Extras server won't be able to make a connection and you won't be able to generate images!

Ensure that you start everything in the proper order, waiting for every program to finish loading before proceeding to the next step:

Extras server can't reconnect to the Stable Diffusion API if it was loaded after.

ERROR: Could not build wheels for hnswlib, which is required to install pyproject.toml-based projects

Before installing the ChromaDB module you must first do one of the following:

Install Visual C++ build tools: https://visualstudio.microsoft.com/visual-cpp-build-tools/
Install the hnswlib package with conda: conda install -c conda-forge hnswlib

ERROR: No matching distribution found for torch==2.0.0+cu117

Mac does not support CUDA, so torch packages should be installed without CUDA support:

Open requirements.txt and requirements-complete.txt files with a Text Editor app.
Remove all +cu117 parts from the package versions. Example: torch==2.0.0+cu117 => torch==2.0.0
Run pip install -r requirements.txt again (change to requirements-complete.txt if needed).

You must specify a list of module names in your python commandline, with the --enable-modules modifier.
See Modules section.

The API Key box in SillyTavern's Extensions panel is only used when you have:
- created a text file named api_key.txt in your Extras install folder, which contains your chosen Extras 'password'.
- started extras with the --secure commandline argument.
This makes the Extras API 'password locked', so only users who have that key in their API Key box can access it.
This is mainly useful for people who want to make their own public public deployment of Extras (colab, etc).
Users running Extras on their own PC for personal use should not type anything into the API Key box.

There are some folks in the community having success running Extras on their phones via Ubuntu on Termux.
However, Extras was not made with mobile support in mind.
No support will be provided for people running Extras on their Android devices.
