No matching distribution found for torch: 5 causes, tested

PyTorch only publishes ready-made builds (wheels), never source code pip could build. So when no wheel matches your Python, your operating system and the index you’re using, pip has nothing at all to offer, and says so: from versions: none. The empty list is the clue. If the list in brackets isn’t empty, jump to cause 4.

Start by checking your Python version and whether it’s 64-bit:

python -c "import sys, platform; print(sys.version, platform.architecture()[0])"

I reproduced every cause below on Windows 11 with pip 26:

1. Your Python is newer than PyTorch

Python 3.15 came out on October 9, 2026. PyTorch 2.14.1, the latest release then, had wheels up to 3.14, so on 3.15.0 pip found none:

ERROR: Could not find a version that satisfies the requirement torch (from versions: none)
ERROR: No matching distribution found for torch

The same happened on Linux. torch 2.15.0 fixed it: it ships wheels for 3.15 on Windows, Linux and macOS. The same thing will happen again with each new Python until PyTorch catches up.

pip install --upgrade torch

py -V:3.14 -m venv .venv
.venv\Scripts\activate
pip install torch

2. 32-bit Python

PyTorch has no 32-bit Windows builds. If the check above ends in 32bit, pip gives exactly the same error, even on a supported version like 3.14.8.

py install 3.14
py -V:3.14 -m venv .venv

3. An old CUDA index URL

For GPU builds, the PyTorch site gives a command with --index-url https://download.pytorch.org/whl/cu…. A command copied from an old tutorial points to an index that has nothing for current Pythons. I checked each index for Python 3.14:

pip install torch --index-url https://download.pytorch.org/whl/cu130

4. A pinned version that’s too old for your Python

When the brackets aren’t empty, pip found torch but not the version you asked for. torch==2.1.2 and torch==2.3.1 are common pins in older projects. On Python 3.14:

ERROR: Could not find a version that satisfies the requirement torch==2.1.2 (from versions: 2.9.0, 2.9.1, 2.10.0, 2.11.0, 2.12.0, 2.12.1, 2.13.0, 2.14.0, 2.14.1, 2.15.0)

That list is every torch release with a wheel for your Python. 2.9.0 is the first one built for 3.14.

pip install "torch==2.14.1"

5. pip install pytorch

pytorch is not PyTorch’s package name. There is a pytorch package on PyPI, version 1.0.2, but it’s a 689-byte placeholder that only exists to stop you:

Exception: You tried to install "pytorch". The package named for PyTorch is "torch"

pip install torch

How this was tested

Windows 11 Pro, on October 12 and 13, 2026, with Python 3.14.5 (64-bit), 3.14.8 (32-bit), 3.14.8 free-threaded and 3.15.0, all from python.org through the Python install manager, each in a fresh virtual environment. The 3.15 Linux check ran on GitHub Actions’ ubuntu-latest (workflow). Every error above is the real output. Re-tested October 30 with torch 2.15.0 on Python 3.15.0 and 3.14.5 (Windows, pip 26); every 2.15.0 and cu132 result above is from that run.
