在使用C++編譯的Tensorflow和Opencv4.0.0的時候，出現以上錯誤，屬於protobuf的版本衝突問題。
主要問題就是，編譯安裝的Tensorflow中的protobuf是3.6的，其中的libprotobuf.so.17,在Opencv中使用的是protobuf2.6.1
的/usr/lib/x86_64-linux-gnu/ 中出現的是libprotobuf.so.9。
在編譯安轉Opencv的時候，使用的GTK3，而GTK3依賴於protobuf2.6.1，而GTK2不會這樣。
所以在編譯opencv的時候，將GTK選項去掉，使用GTK_2_X。
重新編譯安裝，解決問題。
