protobuf安装

安装
1、从 https://github.com/protocolbuffers/protobuf/releases 获取Protobuf编译器protoc
wget https://github.com/protocolbuffers/protobuf/releases/download/v3.6.0/protobuf-all-3.6.0.tar.gz
tar zxvf protobuf-all-3.6.0.tar.gz
cd protobuf-3.6.0/

安装完毕，测试是否安装成功
protoc —version
可能报错：
protoc: error while loading shared libraries: libprotoc.so.17: cannot open shared object file: No such file or directory
解决办法：
export LD_LIBRARY_PATH=/usr/local/lib/
然后再protoc —version，可以看到
libprotoc 3.6.1

conda activate tensorflow
pip install -i https://pypi.tuna.tsinghua.edu.cn/simple tensorflow==1.5.0
