1. paddle version git version: commit 29c16e22 paddle compiled from source, with the options: cmake .. -DWITH_GPU=ON -DWITH_DOC=ON -DWITH_SWIG_PY=ON -DCMAKE_INSTALL_PREFIX=/data/user/program/pddl_build/ make and make install success.
2. protoc --version libprotoc 2.5.0
3. run the sentiment demo: cd /demo/sentiment/data/ ./get_imdb.sh cd .. ./preprocess.sh the above steps are good. However, run ./train.sh, I get the following error msg:
