Stop the program from downloading every time: modify the Launch.py file

[unicornsyay]

launch.txt
change .txt to .py
install in your stable diffusion main folder. Run bat file. and enjoy :) Offline version complete!

Changes:
Added this line as import:
import pkg_resources
#removed the Or because that can cause things to not work.
if not is_installed("torch") and not is_installed("torchvision"):
#made these into seperate calls, so that it doesn't do both if one isn't installed.

if not is_installed("pyngrok"):
    run_pip("install pyngrok")
if not is_installed("ngrok"):
    run_pip("install ngrok")

#These lines have been commented out to show you that they are not needed. With the below if not and if statements for the requirements file,
#we first check if the requirements have been met, and then if not we download them.
#if not os.path.isfile(requirements_file):
# requirements_file = os.path.join(script_path, requirements_file)
#run_pip(f"install -r "{requirements_file}"", "requirements")

#run_extensions_installers(settings_file=args.ui_settings_file)
if not os.path.isfile(requirements_file):
    requirements_file = os.path.join(script_path, requirements_file)

if requirements_file:
    with open(requirements_file, 'r') as file:
        for requirement in file:
            requirement = requirement.strip()
        try:
            pkg_resources.get_distribution(requirement)
            print(f"Requirement '{requirement}' is already installed.")
        except pkg_resources.DistributionNotFound:
            run_pip(f"install {requirement}", f"Requirement: {requirement}")

actually i commented out 2 of your lines then added them back in...the main thing is that you add the below and the import pkg_resources to the beginning of the file. and thhat should fix it. or just download my txt file, change it to .py and put it in your directory.
if requirements_file:
with open(requirements_file, 'r') as file:
for requirement in file:
requirement = requirement.strip()
try:
pkg_resources.get_distribution(requirement)
print(f"Requirement '{requirement}' is already installed.")
except pkg_resources.DistributionNotFound:
run_pip(f"install {requirement}", f"Requirement: {requirement}")

[unicornsyay]

Modified run_extensions_installers and added are_requirements_installed, which should also fix the downloading of files. see attached for new file. Again, just change this to .py and replace it in your folder.

def run_extensions_installers(settings_file):
if not os.path.isdir(extensions_dir):
return

for dirname_extension in list_extensions(settings_file):
    extension_dir = os.path.join(extensions_dir, dirname_extension)
    path_installer = os.path.join(extension_dir, "install.py")
    requirements_file = os.path.join(extension_dir, "requirements.txt")

    # Check if the requirements are already installed
    if are_requirements_installed(requirements_file):
        print(f"Skipping installation for extension {dirname_extension} (requirements already installed)")
        continue

    # Run the installer if it exists
    if os.path.isfile(path_installer):
        try:
            env = os.environ.copy()
            env['PYTHONPATH'] = os.path.abspath(".")

            print(run(f'"{python}" "{path_installer}"', errdesc=f"Error running install.py for extension {extension_dir}", custom_env=env))
        except Exception as e:
            print(e, file=sys.stderr)

def are_requirements_installed(requirements_file):
if not os.path.isfile(requirements_file):
return False

with open(requirements_file, "r", encoding="utf8") as file:
    requirements = file.readlines()

# Check if each requirement is installed
for requirement in requirements:
    package = requirement.strip()
    if not is_installed(package):
        return False

return True

NOTES: After running this several times - I've encountered some errors on startup.... So only implement these changes if you're prepared to correct all the problems in peoples coding...for example things like,
Error loading script: txt2img2img.py
Traceback (most recent call last):
File "J:\Development\git\Stable Diffusion\stable-diffusion-webui\modules\scripts.py", line 256, in load_scripts
script_module = script_loading.load_module(scriptfile.path)
File "J:\Development\git\Stable Diffusion\stable-diffusion-webui\modules\script_loading.py", line 11, in load_module
module_spec.loader.exec_module(module)
File "", line 883, in exec_module
File "", line 241, in _call_with_frames_removed
File "J:\Development\git\Stable Diffusion\stable-diffusion-webui\scripts\txt2img2img.py", line 21, in
from txt2img2img.dependencies import shortcodes
ModuleNotFoundError: No module named 'txt2img2img'

So theres probably 20 or so things like this that I am editing files to get it to load without problems.

Also, I've seen problems on startup that has required me to modify permissions on folders within Webui Stable Diffusion to allow more than one instance - in particular within the repositories folder. A quick fix is to simply delete all the files inside the repository. But I'm still investigating that. So...stay tuned!

Line 8 in webui.py says, "from fastapi import FASTAPI" may throw an exception and refuse to start...if you get that error, change this line to: import fastapi........

[unicornsyay]

Also, there were discrepancies between the requirements and the requirements_versions files that had different version numbers between the two files....so I used the requirements versions file as the master and simply copied them into the requirement.txt file:

accelerate==0.18.0
astunparse
basicsr==1.4.2
blendmodes==2022
clean-fid==0.1.29
einops==0.4.1
fastapi==0.94.0

gfpgan==1.3.8
GitPython==3.1.30
gradio==3.29.0
