What happened?

Dear team conda,

I noticed that the nightly builds for pytorch are out of date. Trying to install the latest version with conda (uninstalled and re-installed just to be sure) only got me version 2.6 (pytorch-2.6.0.dev20241112-py3.12_0). I notice this is the latest version in the conda repo here: https://conda.anaconda.org/pytorch-nightly/osx-arm64.

I then used pip and requested the most recent nightly (yesterday), and I received this version torch-2.7.0-cp312-none-macosx_11_0_arm64.whl, and it included the nightly fixes I was expecting.

From the timestamp on the conda version, it looks like it was last updated on November 11 of last year, so over 5 months out of date.

Expected behavior or outcome

I expect that conda will install the latest version of pytorch, especially considering that it is the package manager suggested by many projects that use pytorch.

Conda list

torch                     2.7.0                    pypi_0    pypi
torchaudio                2.7.0                    pypi_0    pypi

This list was massive, so I'm only showing the relevant bits for pytorch. It shows pypi because I updated it with pip to get the latest nightly, unavailable through conda.
