Installation issue of empanada

[bpavie]

I followed te instruction to install empanada on windows 11 with GPU support but got a error during the last step:

conda create -y -n empanada -c conda-forge python=3.9
conda activate empanada
conda install pyqt
pip install "napari[all]"
conda install pytorch torchvision torchaudio pytorch-cuda=11.8 -c pytorch -c nvidia
pip install empanada-napari=1.2

And got the following error:

This is not mentioned in the documenetation (to my knowledge) that you need to have Microsoft Visual C++ 14.0 or greater installed.

Also, there is a typo on the documentation, it should be with == and not = in pip install empanada-napari==1.2 instead of pip install empanada-napari=1.2

Best,
