Original GitHub issue: https://github.com/RVC-Project/Retrieval-based-Voice-Conversion-WebUI/issues/1053

In Preparing the environment, it states this:

The following commands need to be executed in the environment of Python version 3.8 or higher.

However, if I try to install dependencies (pip install -r requirements-dml.txt) with 3.8.17, I get this error:

ERROR: Ignored the following versions that require a different python version: 1.11.0 Requires-Python <3.13,>=3.9; 1.11.0rc1 Requires-Python <3.13,>=3.9; 1.11.0rc2 Requires-Python <3.13,>=3.9; 1.11.1 Requires-Python <3.13,>=3.9; 1.11.2 Requires-Python <3.13,>=3.9; 1.25.0 Requires-Python >=3.9; 1.25.0rc1 Requires-Python >=3.9; 1.25.1 Requires-Python >=3.9; 1.25.2 Requires-Python >=3.9; 1.26.0b1 Requires-Python <3.13,>=3.9; 3.8.0rc1 Requires-Python >=3.9
ERROR: Could not find a version that satisfies the requirement onnxruntime-directml (from versions: none)
ERROR: No matching distribution found for onnxruntime-directml

This leads me to believe that it works on 3.9-3.12, but not on 3.8.

Now if I try the latest of this range (3.11.4), I get this error:

RuntimeError: Cannot install on Python version 3.11.4; only versions >=3.7,<3.11 are supported.

The range of possible versions was diminished to 3.9-3.10.

Now if I try the latest of this range (3.10.12), I get these errors:

DEPRECATION: omegaconf 2.0.6 has a non-standard dependency specifier PyYAML>=5.1.*. pip 23.3 will enforce this behaviour change. A possible replacement is to upgrade to a newer version of omegaconf or contact the author to suggest that they release a version with a conforming dependency specifiers. Discussion can be found at https://github.com/pypa/pip/issues/12063
ERROR: Could not find a version that satisfies the requirement onnxruntime-directml (from versions: none)
ERROR: No matching distribution found for onnxruntime-directml

If I try with the last version remaining (3.9.17), I get this:

ERROR: Ignored the following versions that require a different python version: 0.52.0 Requires-Python >=3.6,<3.9; 0.52.0rc3 Requires-Python >=3.6,<3.9
ERROR: Could not find a version that satisfies the requirement onnxruntime-directml (from versions: none)
ERROR: No matching distribution found for onnxruntime-directml

So now it wants 3.7-3.8. But we already determined that 3.9-3.12 was required earlier.

In short, it's physically impossible to install dependencies on any and all versions of Python currently in existence.

One workaround is to xargs each requirement into pip install.

cat requirements-dml.txt | xargs -I _ pip install _

Works with Python 3.10.13.

For windows users, you can achieve a similar result with powershell using
Get-Content requirements-dml.txt | ForEach-Object { pip install $_ }

You can update the code to the latest main branch, where this install issue has already been resolved.
