      The installation of cudf-cu12 for version 24.6.1 failed.

      This is a special placeholder package which downloads a real wheel package
      from https://pypi.nvidia.com. If https://pypi.nvidia.com is not reachable, we
      cannot download the real wheel file to install.

      You might try installing this package via

  $ pip install --extra-index-url https://pypi.nvidia.com cudf-cu12
  ```

  Here is some debug information about your platform to include in any bug
  report:

  Python Version: CPython 3.9.20
  Operating System: Windows 10
  CPU Architecture: AMD64
  Driver Version: 556.12
  CUDA Version: 12.5

note: This error originates from a subprocess, and is likely not a problem with pip. error: metadata-generation-failed

× Encountered error while generating package metadata. ╰─> See above for output.

note: This is an issue with the package mentioned above, not pip. hint: See above for details.

A simple solution is to install using recommended command, thus losing out on the version specified and installing older version. 

is there an alternate solution to this

Hi @adiv5, Cucim for Windows isn't available on PyPI yet. You can try following the manual installation steps described here. However, please note that the HEST library will still work even if you don't have Cucim installed; it will default to using OpenSlide instead.

Thanks @pauldoucet.
