Secondly, find out if you are running 64-bit or 32-bit Python. The building
command depends on the architecture of the Python interpreter. You can check
the architecture by running the following in ``cmd`` or ``powershell``
console:
Build scikit-learn by running the following command in your `sklearn-env` conda environment
or virtualenv:

.. prompt:: bash $

python -c "import struct; print(struct.calcsize('P') * 8)"

For 64-bit Python, configure the build environment by running the following
commands in ``cmd`` or an Anaconda Prompt (if you use Anaconda):

.. sphinx-prompt 1.3.0 (used in doc-min-dependencies CI task) does not support `batch` prompt type,
.. so we work around by using a known prompt type and an explicit prompt text.
..
.. prompt:: bash C:\>

SET DISTUTILS_USE_SDK=1
"C:\Program Files (x86)\Microsoft Visual Studio\2022\BuildTools\VC\Auxiliary\Build\vcvarsall.bat" x64

.. note::
The previous command is for the 2022 version of Visual Studio. If you
have a different version, you will need to adjust the year in the path accordingly.

Replace ``x64`` by ``x86`` to build for 32-bit Python.

Please be aware that the path above might be different from user to user. The
aim is to point to the "vcvarsall.bat" file that will set the necessary
environment variables in the current command prompt.

Finally, build scikit-learn with this command prompt:

.. prompt:: bash $

pip install --editable . \
--verbose --no-build-isolation \
--config-settings editable-verbose=true
pip install --editable . --verbose --no-build-isolation --config-settings editable-verbose=true
