Question: can I start a rendering from the command line?

[vicmortelmans]

Hi, thanks!!

I got the API working, mainly by inspecting the calls made by the web GUI.

There are two fields in the posted data that I don't know what they're for and that seem to be mandatory:

• fn_index: when inspecting, it was set to 10. I tried other values of 0 or 1, but then there's an error. It works with 10, but what's the purpose of this field?
• session_hash: I can guess that this is used by the GUI to identify when making subsequent calls to the server. It works with a fixed string (that I copied when inspecting the GUI). I suppose it would be better if I'd generate my own hashes, but how are they built?

The data array contains all the settings that are available in the GUI. So far I copied the defaults (again: upon inspection) and only tried modifying the text and the size fields.

Here's code that works for me:

#!/bin/sh
curl --header "Content-Type: application/json" \
     --request POST \
     --data '{"fn_index":10,"data": ["<text goes here>","","None","None",20,"Euler a",false,false,1,1,7,-1,-1,0,0,0,false,512,512,false,false,0.7,"None",false,false,null,"","Seed","","Steps","",true,null,"",""],"session_hash":"ejz5r41u2pi2"}' \
        http://localhost:7860/api/predict/

And in Python:

#!/usr/bin/python3
import requests
from requests.structures import CaseInsensitiveDict
import json
from base64 import urlsafe_b64decode

url = "http://localhost:7860/api/predict/"

headers = CaseInsensitiveDict()
headers["Content-Type"] = "application/json"

text = "<text goes here>"
size = 512

data_json = {"fn_index":10,"data": [text,"","None","None",20,"Euler a",False,False,1,1,7,-1,-1,0,0,0,False,size,size,False,False,0.7,"None",False,False,None,"","Seed","","Steps","",True,None,"",""],"session_hash":"ejz5r41u2pi"}
data = json.dumps(data_json)

resp = requests.post(url, headers=headers, data=data)

if resp.status_code == 200:
    with open("predict.png","wb") as f:
        b64string = resp.json()["data"][0][0].split(',')[1]
        f.write(urlsafe_b64decode(b64string))
    print("Image saved to file")
else:
    print(json.dumps(resp.json()))
    print("Status code: " + str(resp.status_code))
    print("Nothing saved to file")

@vicmortelmans when you open the ui, there is a button at the bottom to view the api, you can then curl against it with the prompts / parameters, and get the result from the output folder. I haven't tried it personally, but it should work, in theory at least.

Glad it worked! the questions you have rely on the internals of gradio and the UI itself, which is unfortunately out of scope of this repo (here are the containers only).

You can definitely try asking your questions in the main repo:
https://github.com/AUTOMATIC1111/stable-diffusion-webui

The community there is much larger and you would probably find the answers you are looking for 👍
