Can not install with conda.

[YAETHeryk]

I have a conda env with python 3.11.10, and I use the command
conda install -c conda-forge neuralforecast
Then I get:

Platform: win-64
Collecting package metadata (repodata.json): done

LibMambaUnsatisfiableError: Encountered problems while solving:

Hey. Are you able to install just ray-tune?

[YAETHeryk]

Sorry for the late reply after the weekend. I fixed the issue by installing Ray with pip instead. Looks like the Conda support for Ray isn't as good.
Since the official Ray docs say: the Conda packages are maintained by the community, not the Ray team. So when using a Conda environment, it’s better to install Ray from PyPI using pip install ray.
