PyTorch will stop publishing Anaconda packages that depend on Anaconda’s default packages due to the high maintenance costs for conda builds which are not justifiable with the ROI we observe today (as seen in download discrepancies between PyPI vs. conda). We are directing users to utilize our official wheel packages from download.pytorch.org or PyPI, or switch to utilizing conda-forge (pytorch-cpu, pytorch-gpu) packages if they would like to continue to use conda.
