[BUG] installation not working on windows

[Wiilly-B]

• PyTorch-Forecasting version: 1.0.0
• PyTorch version: 2.3.0+cpu
• Python version: 3.10
• Operating System: Windows 11

Expected behavior

I executed code pip install pytorch-forecasting to install pytorch forecasting and expected to get result of being able to use pytorch forecasting

Actual behavior

I receive an error when pip installing

However, the result was

      [end of output]

  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.

Code to reproduce the problem

pip install pytorch-forecasting

Paste the command(s) you ran and the output. Including a link to a colab notebook will speed up issue resolution. If there was a crash, please include the traceback here. The code used to initialize the TimeSeriesDataSet and model should be also included.

Cython.Compiler.Errors.CompileError: sklearn\svm\_liblinear.pyx

Looks like a problem with installation of sklearn actually.

@Wiilly-B Did you figure out a way around this? Facing the same issue while installing pytorch-forecasting

[fkiraly]

Windows was not supported on version 1.0.0 (at least, it was not tested), and there are some remaining compatibility issues: https://github.com/jdb78/pytorch-forecasting/issues/1623.

This should be, hopefully, resolved with the next release.
