# CUDA only: Add LAPACK support for the GPU if needed
conda install -c pytorch magma-cuda110 # or the magma-cuda* that matches your CUDA version from https://anaconda.org/pytorch/repo
在MacOS上
# Add these packages if torch.distributed is needed
conda install pkg-config libuv
在Windows上
# Add these packages if torch.distributed is needed.# Distributed package support on Windows is a prototype feature and is subject to changes.
conda install -c conda-forge libuv=1.39
