[Bug]: Some builtin-extensions throw missing modules (launch due to flowdas-meta dependency) errors when webui is run from absolute path

[Th3Rom3]

Checklist

• [X] The issue exists after disabling all extensions
• [X] The issue exists on a clean installation of webui
• [ ] The issue is caused by an extension, but I believe it is caused by a bug in the webui
• [X] The issue exists in the current version of the webui
• [X] The issue has not been reported before recently
• [ ] The issue has been reported before but has not been fixed yet

What happened?

General functions of the webui work without a problem but the installation routines of some of the builtin extensions (forge_legacy_preprocessor; sd_forge_controlnet) which are called by launch.py are not executed correctly due to a missing launch python module which relies on deprecated dependencies.

Addendum: Additional testing showed that this only occurs when running launch.py from an absolute path. Launching it from within the forge main folder via cd [...]/stable-diffusion-webui-forge seemingly fixes the issue.

Steps to reproduce the problem

Clone repository and run via python /absolute/path/from/root/launch.py

What should have happened?

Setup of integrated extensions should have completed gracefully.

What browsers do you use to access the UI ?

Additional information

The dependencies of the mentioned launch module flowdas-meta are no longer available via the normal means (https://libraries.io/pypi/flowdas-meta). As such installation of the launch module is no longer possible without manually manipulating the dependencies.

[Th3Rom3]

I have tested an additional variety of configurations and I figured that this problem only occurs when running the webui by invoking launch.py via an absolute path. Running it from within the forge folder seems to mitigate the problem.

I assume this is probably enough to know how to work arround the problem and the issue can ultimately be closed. Nevertheless I wanted to leave it up for a few days and keep the information available for posterity.

Will close in 7 days unless this issue gets further feedback.
