Same, with preceding error:

ERROR: Could not find a version that satisfies the requirement rembg==2.0.38 (from versions: 2.0.41, 2.0.43, 2.0.44, 2.0.45, 2.0.46, 2.0.47, 2.0.48, 2.0.49)
ERROR: No matching distribution found for rembg==2.0.38

I think the problem comes from line pip install rembg==2.0.38 --no-deps --prefer-binary in the install.py that has no matching version. You can change the line in the script to a matching version, e.g. rembg==2.0.41

@battester commented on GitHub (Dec 4, 2023):

I met this but I solved it by changing the rembg version in the install.py from 2.0.38 to 2.0.52, bcz when I run the webui script, it showed “ERROR: No matching distribution found for rembg==2.0.38”， so I go to pycharm to check if any version avaliable and then found the 2.0.52 version.
So I fix the version in install.py and then rerun the webui.sh, problem solved.

@Momin9 commented on GitHub (Jun 5, 2024):

It seems that there's an error loading the script postprocessing_rembg.py due to a missing module named rembg.

To resolve this issue, you need to install the rembg module. You can do this using pip, the Python package manager, by running the following command in your terminal or command prompt:

**pip install rembg**

This command will download and install the rembg module along with its dependencies. After the installation is complete, you should be able to load the script postprocessing_rembg.py without encountering the ModuleNotFoundError.
