Python 3.14t free-threading installation instructions. Windows server 2025.

It's simple, just install Python.

in the console

python3.14t -m venv venv314t
cd venv314t
Scripts\activate
python.exe -m pip install --upgrade pip
pip install numpy
pip install matplotlib
pip install psutil
pip install cma
pip install cmaes
pip3 install --pre torch --index-url https://download.pytorch.org/whl/nightly/cpu
pip list
Very good!

Next, the pyzmq library was a hurdle previously. But now there's a wonderful new version where everything works.
pip install pyzmq
pip install tornado
pip install platformdirs
Very good!

All that's left to do is fix it:
pip install jupyter-core
pip install jupyter-client
pip install spyder-kernels

All hope is in your hands.
