To my surprise, I wasn’t able to install Pytorch for a project on my Macbook Pro M1 today (MacOS Sequoia 15.2). I kept getting this error when running pip3 install -r requirements.txt:

ERROR: Ignored the following versions that require a different python version: 1.21.2 Requires-Python >=3.7,<3.11; 1.21.3 Requires-Python >=3.7,<3.11; 1.21.4 Requires-Python >=3.7,<3.11; 1.21.5 Requires-Python >=3.7,<3.11; 1.21.6 Requires-Python >=3.7,<3.11; 1.26.0 Requires-Python <3.13,>=3.9; 1.26.1 Requires-Python <3.13,>=3.9
ERROR: Could not find a version that satisfies the requirement torch==2.7.0.dev20250116 (from versions: none)
ERROR: No matching distribution found for torch==2.7.0.dev20250116

I tried it manually: pip3 install torch, no luck:

pip install torch
Looking in indexes: https://pypi.org/simple, https://pypi.ngc.nvidia.com
ERROR: Could not find a version that satisfies the requirement torch (from versions: none)
ERROR: No matching distribution found for torch

Solution

This is what I came up with and it works fine:

pip3 install --pre torch torchvision torchaudio --index-url https://download.pytorch.org/whl/nightly/cpu
