Windows installation

Hello, when installing darts libary using conda as per instructions with python 3.7 i get the following error:

PS C:\Users\XXXX> conda install -c conda-forge u8darts-all
Collecting package metadata (current_repodata.json): done
Solving environment: failed with initial frozen solve. Retrying with flexible solve.
Solving environment: failed with repodata from current_repodata.json, will retry with next repodata source.

UnsatisfiableError: The following specifications were found to be incompatible with each other:

Output in format: Requested package -> Available versions

Do you have any ideas why this is happening?

I can install prophet on it’s own but not the darts libary.

Thanks,

Adam

@GitHunter0 glad that worked!

Regarding the size: darts itself is very small, but some of the dependencies of u8darts-all might not be. PyTorch on Windows should take about 1.6 GB, so I’m not sure where the rest comes from. Maybe CUDA and other dependencies? You could also try to install u8darts-torch if you’re not using Prophet and pmdarima.

I imagine that might be because you are reinstalling PyTorch using pip. Could you try recreating the conda environment and reinstalling the prerequisites using conda, but using pip install u8darts instead of pip install darts?
