Unable to install due to the use of an outdated dependency somewhere.
The building (with wheel) of a dependency fails on modern python. Related to #2644
I attempted to use both pip and poetry, it won't work. Here's the poetry log.
C:\RVC1006AMD_Intel1>C:\Users\me\AppData\Roaming\Python\Scripts\poetry install
The "poetry.dev-dependencies" section is deprecated and will be removed in a future version. Use "poetry.group.dev.dependencies" instead.

Note: This error originates from the build backend, and is likely not a problem with poetry but one of the following issues with rpds-py (0.9.2)
- not supporting PEP 517 builds
- not specifying PEP 517 build requirements correctly
- the build requirements are incompatible with your operating system or Python version
- the build requirements are missing system dependencies (eg: compilers, libraries, headers).
You can verify this by running pip wheel --no-cache-dir --use-pep517 "rpds-py (==0.9.2)".
- Installing sniffio (1.3.0)
The pip log says: RuntimeError: Cannot install on Python version 3.13.5; only versions >=3.7,<3.11 are supported.
I am not sure what uses maturin and is trying to build something in rust, but I do know this dependency is related to Rust https://docs.rs/rpds/latest/rpds/
You can find the package here: https://github.com/RVC-Project/Retrieval-based-Voice-Conversion-WebUI/blob/7ef19867780cf703841ebafb565a4e47d1ea86ff/poetry.lock#L3469
Please update the dependencies or something, or update the readme file to instruct people to download a specific python version.
