RHEL7下安装使用TensorFlow和kcws

0.安装依赖包

#用pip安装python科学计算库numpy,sklearn,scipy
su -
wget http://dl.fedoraproject.org/pub/epel/7/x86_64/e/epel-release-7-8.noarch.rpm
yum install epel-release--.noarch.rpm
yum install python2-pip.noarch
yum install gcc-c++.x86_64
pip install --upgrade pip
pip install numpy
pip install sklearn
pip install scipy

1.安装bazel

Bazel是一个类似于Make的工具，是Google为其内部软件开发的特点量身定制的工具，2015年开源。

cd ~
wget https://github.com/bazelbuild/bazel/archive/0.4.0.tar.gz
tar xzvf 0.4..tar.gz
cd bazel-0.4./
./compile.sh
sudo cp output/bazel /usr/bin/
which bazel
#配置bash_completion
bazel build //scripts:bazel-complete.bash
sudo cp bazel-bin/scripts/bazel-complete.bash /etc/bash_completion.d/

2.安装TensorFlow

#下载TensorFlow源代码
git clone https://github.com/tensorflow/tensorflow
cd tensorflow/
./configure
#Create the pip package and install
bazel build -c opt //tensorflow/tools/pip_package:build_pip_package
bazel-bin/tensorflow/tools/pip_package/build_pip_package /tmp/tensorflow_pkg
sudo pip install /tmp/tensorflow_pkg/tensorflow-*-cp27-none-linux_x86_64.whl 

3.安装kcws - 97.5%准确率的深度学习中文分词（字嵌入+Bi-LSTM+CRF）https://github.com/koth/kcws

git clone https://github.com/koth/kcws.git
cd kcws/
#下载语料库people2014.tar.gz
tar xzvf people2014.tar.gz # 解压到~/kcws/
./configure
#编译后台服务
bazel build //kcws/cc:seg_backend_api
python kcws/train/process_anno_file.py ./ chars_for_w2v.txt
bazel build third_party/word2vec:word2vec
#使用word2vec 训练 chars_for_w2v (注意-binary ),得到字嵌入结果vec.txt
./bazel-bin/third_party/word2vec/word2vec -train chars_for_vec.txt -output kcws/models/vec.txt -size  -sample 1e- -negative  -hs  -binary  -iter
bazel build kcws/train:generate_training
./bazel-bin/kcws/train/generate_training kcws/models/vec.txt ./ all.txt
python kcws/train/filter_sentence.py all.txt
python kcws/train/train_cws_lstm.py --word2vec_path ./kcws/models/vec.txt --train_data_path ./train.txt --test_data_path test.txt --max_sentence_len  --learning_rate 0.001
