To launch the web UI in the future after it is already installed, run
this same "start" script.
# Updating
# Updating the web UI
Run the "update" script. This will only install the updates, so it should
be much faster than the initial installation.
May need to delete the 'text-generation-webui\repositories\GPTQ-for-LLaMa'
folder if GPTQ-for-LLaMa needs to be updated.
# Adding flags like --chat, --notebook, etc
Edit the "webui.py" script using a text editor and add the desired flags
to the CMD_FLAGS variable at the top. It should look like this:
CMD_FLAGS = '--chat --model-menu'
CMD_FLAGS = '--chat'
For instance, to add the --notebook flag, change it to
For instance, to add the --api flag, change it to
CMD_FLAGS = '--notebook --model-menu'
CMD_FLAGS = '--chat --api'
