# This file contains step-by-step instructions on how to build the Python API for CNTK

|
|
|
# no support yet for python 2.7
|
|
# recommended python version is 3.4 (with numpy & scipy)
|
|
# supported platform: 64 bit
|
|
|
|
# Set up compiler and its variant

# Generate .cxx and .py out of .i. Please check the path to the SwigWin binaries inside swig.bat
|
|
# run swig.bat from within swig folder
|
|
swig.bat
|
|
|
|
|
|
# a) If you are just building to use it locally:
|
|
# Build -> generate .pyd
|
|
|
|
# 1) go two levels up
|
|
# 2) run the following:
|
|
python .\setup.py build_ext -if -c msvc --plat-name=win-amd64
|
|
|
|
# 3) add to PATH the path to cntk dlls (e.g. e:\CNTK\x64\Release)
|
|
SET PATH=%PATH%;<your CNTK release path e.g., e:\CNTK\x64\Release
|
|
# 4) add to PYTHONPATH the path to the python examples (e.g. e:\CNTK\bindings\python\examples)
|
|
SET PYTHONPATH=e:\CNTK\bindings\python\examples
|
|
# 5) test by running any of the examples or running py.test from the inside bindings\python directory
|
|
|
|
# b) If you want to package it:
|
|
# 1) install the following:
|
|
pip install twine
|
|
pip install wheel
|
|
|
|
# 2) go two levels up & run:
|
|
python .\setup.py build_ext -if -c msvc --plat-name=win-amd64 bdist_wheel
|
|
|
|
# 3) put the wheel file on some http server
|
|
|
|
# 4) from your machine, run pip install
|
|
pip install http://your-url:your-port/cntk-0.0.0-cp34-cp34m-win_amd64.whl
|
|
|
|
# 5) check that it is loaded correctly
|
|
python
|
|
>>> import cntk
|
|
|
|
# 6) Running examples:
|
|
# Clone the python examples folder from the CNTK repository and add its path to PYTHONPATH
|
|
# (e.g. setx PYTHONPATH %PYTHONPATH%;C:\work\cntk\bindings\python\examples in an Admin shell,
|
|
# or rather setx PYTHONPATH C:\work\cntk\bindings\python\examples if no PYTHONPATH defined yet).
|
|
# Try to run any of the examples, some examples come up with s script that fetches and prepares the data,
|
|
# other examples use data files that are checked in inside the cntk repository.
