最近在学习 image tagging 的问题，获取模型时使用 wget 链接网址超时的问题，请教各位大神，不知道能不能我自己下好解压

原文件如下：是 get_word2vec_model.sh 文件。
source common.ini

if [ ! -d "$rootpath" ]; then
echo "rootpath $rootpath does not exit"
exit
fi


DIR="$( cd "$(dirname "$0")" ; pwd -P )"
cd $DIR

echo "Downloading..."

wget http://www.mmc.ruc.edu.cn/research/hierse/flickr4m.word2vec.tar.gz

echo "Unzipping..."

tar -xf flickr4m.word2vec.tar.gz -C $rootpath && rm -f flickr4m.word2vec.tar.gz

echo "Done."

出错结果如下：
f@f-Lenovo:~/workspace/zero-shot/hierse-master$ ./get_word2vec_model.sh
