[BUG] AssertionError: Unable to pre-compile ops without torch installed. Please install torch before attempting to pre-compile ops.

When I run pip install deepspeed on my Windows 11 machine in a virtual environment with Python 3.12.4, PyTorch 2.4.1 and CUDA 12.4 installed, I get the below error:

Hi @umarbutler - looks like you're on Windows. The wheel we publish on Windows has a specific set of requirements, and it looks like you are pulling down the linux wheel.

See the Windows version here, you may need to modify your python version to get it to grab this

https://pypi.org/project/deepspeed/0.15.0/#files

Hi @umarbutler - did that resolve your issue?
