intel平台优化
TensorFlow *是深度学习领域中主要使用的机器学习框架，要求高效利用计算资源。 为了充分利用英特尔架构和提高性能，TensorFlow *库已经使用英特尔MKL-DNN原语进行了优化，该原语是深度学习应用的流行性能库。
已进行优化的平台
有三种安装方式。
1. 使用pip
pip install -i https://pypi.anaconda.org/intel/simple tensorflow
2. anaconda 安装
video
3. 自己编译
前两种方式可能不支持最新的指令集。
首先安装 dnf Bazel
安装 Bazel
pushd /var/tmpURL=https://github.com/bazelbuild/bazel/releases/latest LASTURL=$(curl $URL -s -L -I -o /dev/null -w '%{url_effective}') BZ_VERSION=${LASTURL##*/} wget https://github.com/bazelbuild/bazel/releases/download/$BZ_VERSION/bazel-$BZ_VERSION-installer-linux-x86_64.shchmod +x bazel-* ./bazel-* export PATH=/usr/local/bin:$PATHpopd
centos 7.4 can not install `dnf`from epel
WARNING: EPEL 7 DNF is very old and has issues to include security flaws. This appears to be the reason it was removed. That said here is the work around to get it working on Centos 7.
cat > /etc/yum.repos.d/dnf-stack-el7.repo << EOF [dnf-stack-el7] name=Copr repo for dnf-stack-el7 owned by @rpm-software-management baseurl=https://copr-be.cloud.fedoraproject.org/results/@rpm-software-management/dnf-stack-el7/epel-7-\$basearch/ skip_if_unavailable=True gpgcheck=1 gpgkey=https://copr-be.cloud.fedoraproject.org/results/@rpm-software-management/dnf-stack-el7/pubkey.gpg enabled=1 enabled_metadata=1 EOFyum install dnf
centos 7会出现这个bug:
dnf copr plugin not present in dnf-plugins-core
因为EPEL 7 DNF 已经被移除了centos 7 install dn，还需要：
wget http://springdale.math.ias.edu/data/puias/unsupported/7/x86_64/dnf-plugins-core-0.1.5-3.sdl7.noarch.rpm
dnf install copr-cli
sudo dnf update
dnf copr enable vbatts/bazel
centos 可以直接安装bazel下：
wget https://copr.fedorainfracloud.org/coprs/vbatts/bazel/repo/epel-7/vbatts-bazel-epel-7.repo -P /etc/yum.repos.d/ yum install dnf-plugins-core-0.1.5-3.sdl7.noarch.rpm yum install bazel
install tf:
git clone https://github.com/tensorflow/tensorflow tensorflow cd tensorflow
Compiling TensorFlow with Intel C Compiler
CC=icc bazel build --verbose_failures --config=mkl --copt=-msse4.2 --copt="-DEIGEN_USE_VML" -c opt //tensorflow/tools/pip_package:build_pip_package
bazel build --config=mkl -c opt --copt=-mavx --copt=-mavx2 --copt=-mfma --copt=-mavx512f --copt=-mavx512dq --copt=-mavx512cd --copt=-mavx512bw --copt=-mavx512vl --copt="-DEIGEN_USE_VML" //tensorflow/tools/pip_package:build_pip_package

# The script set the following environment variables for tf docker: export TF_DOCKER_BUILD_TYPE=mkl # export TF_DOCKER_BUILD_TYPE=CPU # CPU or GPU imageexport TF_DOCKER_BUILD_IS_DEVEL=YES # Is this developer imageexport TF_DOCKER_BUILD_DEVEL_BRANCH=r1.99 # export TF_DOCKER_BUILD_DEVEL_BRANCH=master # (Required if TF_DOCKER_BUILD_IS_DEVEL is YES) # Specifies the branch to checkout for devel docker images# export TF_DOCKER_BUILD_CENTRAL_PIP # (Optional) # If set to a non-empty string, will use it as the URL from which the # pip wheel file will be downloaded (instead of building the pip locally).# export TF_DOCKER_BUILD_CENTRAL_PIP_IS_LOCAL # (Optional) # If set to a non-empty string, we will treat TF_DOCKER_BUILD_CENTRAL_PIP # as a path rather than a url.export TF_DOCKER_BUILD_IMAGE_NAME=native-mkl-tf # (Optional) # If set to any non-empty value, will use it as the image of the # newly-built image.
