异常解决:cococaption包出现找不到edu.stanford.nlp.semgraph.semgrex.SemgrexPattern错误

前言

在视频字幕、图像字幕任务中，必然用到的一个依赖包是coco-caption。该依赖主要作用是用来评价模型所生成的描述的准确性，其中spice.py文件中，执行以下命令时会报错：

java -jar -Xmx8G spice-1.0.jar coco-caption/pycocoevalcap/spice/tmp/tmp1wdsxtug -out coco-caption/pycocoevalcap/spice/tmp/tmpkj4h9o4j -subset -silent

spice 错误

raise CalledProcessError(retcode, cmd)
subprocess.CalledProcessError: Command '['/home/ubuntu/jdk1.8.0_333/bin/java', '-jar', '-Xmx8G', 'spice-1.0.jar', '/home/chenzw/code/SMAN/coco-caption/pycocoevalcap/spice/tmp/tmp98_yx34s', '-cache', '/home/chenzw/code/SMAN/coco-caption/pycocoevalcap/spice/cache/1658759575.7687752', '-out', '/home/chenzw/code/SMAN/coco-caption/pycocoevalcap/spice/tmp/tmpicxj0dmv', '-subset', '-silent']' returned non-zero exit status 1.

解决方法

执行coco-caption项目目录下的get_stanford_models.sh文件即可。

bash get_stanford_models.sh

该文件的具体过程其实就是 下载我们所缺的那个包。其内容为：

#!/usr/bin/env sh
# This script downloads the Stanford CoreNLP models.

CORENLP=stanford-corenlp-full-2015-12-09
SPICELIB=pycocoevalcap/spice/lib
JAR=stanford-corenlp-3.6.0

DIR="$( cd "$(dirname "$0")" ; pwd -P )" cd $DIR if [ -f $SPICELIB/$JAR.jar ]; then echo "Found Stanford CoreNLP." else echo "Downloading..." wget http://nlp.stanford.edu/software/$CORENLP.zip echo "Unzipping..." unzip $CORENLP.zip -d $SPICELIB/ mv $SPICELIB/$CORENLP/$JAR.jar $SPICELIB/ mv $SPICELIB/$CORENLP/$JAR-models.jar $SPICELIB/ rm -f $CORENLP.zip rm -rf $SPICELIB/$CORENLP/ echo "Done."
fi

完美解决。
