Build a TensorFlow pip package from the source and install it on Windows.
Setup for Windows
Install the following build tools to configure your Windows development environment.
Install Python and the TensorFlow package dependencies
Install a
Python 3.9 64-bit release for Windows.
Select pip as an optional feature and add it to your %PATH%
environmental
variable.
Install the TensorFlow pip package dependencies:
pip3 install -U pip
pip3 install -U six numpy wheel packaging
pip3 install -U keras_preprocessing --no-deps
The dependencies are listed in the
setup.py
file under REQUIRED_PACKAGES
.
Install Bazel
Install Bazel, the build tool used to compile TensorFlow. For Bazel version, see the tested build configurations for Windows. Configure Bazel to build C .
Add the location of the Bazel executable to your %PATH%
environment variable.
Install MSYS2
Install MSYS2 for the bin tools needed to
build TensorFlow. If MSYS2 is installed to C:\msys64
, add
C:\msys64\usr\bin
to your %PATH%
environment variable. Then, using cmd.exe
,
run:
pacman -Syu (requires a console restart) pacman -S git patch unzip pacman -S git patch unzip rsync
Install Visual C Build Tools 2022
Install the Visual C build tools 2022. This comes with Visual Studio Community 2022 but can be installed separately:
- Go to the Visual Studio downloads,
- Select Tools for Visual Studio or Other Tools, Framework and Redistributables,
- Download and install:
- Build Tools for Visual Studio 2022
- Microsoft Visual C Redistributables for Visual Studio 2022
Install LLVM
- Go to the LLVM downloads,
- Download and install Windows-compatible LLVM in C:/Program Files/LLVM e.g., LLVM-17.0.6-win64.exe
Install GPU support (optional)
See the Windows GPU support guide to install the drivers and additional software required to run TensorFlow on a GPU.
Download the TensorFlow source code
Use Git to clone the
TensorFlow repository
(git
is installed with MSYS2):
git clone https://github.com/tensorflow/tensorflow.git
cd tensorflow
The repo defaults to the master
development branch. You can also check out a
release branch
to build:
git checkout branch_name # r1.9, r1.10, etc.
Optional: Environmental Variable Set Up
Run the following commands before running the build command to avoid issues with package creation:
(If the below commands were set up while installing the packages, please ignore them). Run set
to check if all the paths were set correctly, run echo %Environmental Variable%
e.g., echo �ZEL_VC%
to check the path set up for a specific Environmental Variable
Python path set up issue tensorflow:issue#59943,tensorflow:issue#9436,tensorflow:issue#60083
set PATH=path/to/python;%PATH% # [e.g. (C:/Python311)] set PATH=path/to/python/Scripts;%PATH% # [e.g. (C:/Python311/Scripts)] set PYTHON_BIN_PATH=path/to/python_virtualenv/Scripts/python.exe set PYTHON_LIB_PATH=path/to/python virtualenv/lib/site-packages set PYTHON_DIRECTORY=path/to/python_virtualenv/Scripts
Bazel/MSVC/CLANG path set up issue tensorflow:issue#54578
set BAZEL_SH=C:/msys64/usr/bin/bash.exe set BAZEL_VS=C:/Program Files/Microsoft Visual Studio/2022/BuildTools set BAZEL_VC=C:/Program Files/Microsoft Visual Studio/2022/BuildTools/VC set Bazel_LLVM=C:/Program Files/LLVM (explicitly tell Bazel where LLVM is installed by BAZEL_LLVM, needed while using CLANG) set PATH=C:/Program Files/LLVM/bin;%PATH% (Optional, needed while using CLANG as Compiler)
Optional: Configure the build
TensorFlow builds are configured by the .bazelrc
file in the repository's
root directory. The ./configure
or ./configure.py
scripts can be used to
adjust common settings.
If you need to change the configuration, run the ./configure
script from
the repository's root directory.
python ./configure.py
This script prompts you for the location of TensorFlow dependencies and asks for
additional build configuration options (compiler flags, for example). The
following shows a sample run of python ./configure.py
(your session may
differ):
Build and install the pip package
The pip package is built in two steps. A bazel build
command creates a
"package-builder" program. You then run the package-builder to create the
package.
Build the package-builder
tensorflow:master repo has been updated to build 2.x by default.
Install Bazel and use
bazel build
to create the TensorFlow package-builder.
bazel build //tensorflow/tools/pip_package:wheel
CPU-only
Use bazel
to make the TensorFlow package builder with CPU-only support:
Build with MSVC
bazel build --config=opt --repo_env=TF_PYTHON_VERSION=3.11 //tensorflow/tools/pip_package:wheel --repo_env=WHEEL_NAME=tensorflow_cpu
Build with CLANG
Use --config=win_clang
to build TenorFlow with the CLANG Compiler:
bazel build --config=win_clang --repo_env=TF_PYTHON_VERSION=3.11 //tensorflow/tools/pip_package:wheel --repo_env=WHEEL_NAME=tensorflow_cpu
GPU support
To make the TensorFlow package builder with GPU support:
bazel build --config=opt --config=cuda --define=no_tensorflow_py_deps=true //tensorflow/tools/pip_package:build_pip_package
Commands to clean the bazel cache to resolve errors due to invalid or outdated cached data, bazel clean with --expunge flag removes files permanently
bazel clean bazel clean --expunge
Bazel build options
Use this option when building to avoid issues with package creation: tensorflow:issue#22390
--define=no_tensorflow_py_deps=true
See the Bazel command-line reference for build options.
Building TensorFlow from source can use a lot of RAM. If your system is
memory-constrained, limit Bazel's RAM usage with: --local_ram_resources=2048
.
If building with GPU support, add --copt=-nvcc_options=disable-warnings
to suppress nvcc warning messages.
Build the package
To build a pip package, you need to specify the --repo_env=WHEEL_NAME flag. Depending on the provided name, the package will be created. For example:
To build tensorflow CPU package:
bazel build //tensorflow/tools/pip_package:wheel --repo_env=WHEEL_NAME=tensorflow_cpu
To build nightly package, set tf_nightly
instead of tensorflow
, e.g.
to build CPU nightly package:
bazel build //tensorflow/tools/pip_package:wheel --repo_env=WHEEL_NAME=tf_nightly_cpu
As a result, generated wheel will be located in
bazel-bin/tensorflow/tools/pip_package/wheel_house/
Install the package
The filename of the generated .whl
file depends on the TensorFlow version and
your platform. Use pip install
to install the package, for example:
pip install bazel-bin/tensorflow/tools/pip_package/wheel_house/tensorflow-version-tags.whl
Build using the MSYS shell
TensorFlow can also be built using the MSYS shell. Make the changes listed
below, then follow the previous instructions for the Windows native command line
(cmd.exe
).
Disable MSYS path conversion
MSYS automatically converts arguments that look like Unix paths to Windows
paths, and this doesn't work with bazel
. (The label //path/to:bin
is
considered a Unix absolute path since it starts with a slash.)
export MSYS_NO_PATHCONV=1
export MSYS2_ARG_CONV_EXCL="*"
Set your PATH
Add the Bazel and Python installation directories to your $PATH
environmental
variable. If Bazel is installed to C:\tools\bazel.exe
, and Python to
C:\Python\python.exe
, set your PATH
with:
# Use Unix-style with ':' as separatorexport PATH="/c/tools:$PATH"
export PATH="/c/path/to/Python:$PATH"
For GPU support, add the CUDA and cuDNN bin directories to your $PATH
:
export PATH="/c/Program Files/NVIDIA GPU Computing Toolkit/CUDA/v11.0/bin:$PATH"
export PATH="/c/Program Files/NVIDIA GPU Computing Toolkit/CUDA/v11.0/extras/CUPTI/libx64:$PATH"
export PATH="/c/tools/cuda/bin:$PATH"
