我使用Python3在Ubuntu 14.04,和我對67頁的原始文本的文章語料庫運行斯坦福POSTagger,thje節錄python腳本如下:斯坦福POSTagger,Java堆SPCE內存
from nltk.tag.stanford import POSTagger
with open('the_file.txt','r') as file:
G=file.readlines()
stan=[]
english_postagger = POSTagger('models/english-bidirectional-distsim.tagger', 'stanford-postagger.jar')
for line in g:
stan.append(english_postagger.tag(tokenize_fast(line)))
經過多次迭代其中,我得到以下錯誤:

我也運行在命令行斯坦福postagger爲:
java -mx300m -classpath stanford-postagger.jar edu.stanford.nlp.tagger.maxent.MaxentTagger -model models/wsj-0-18-bidirectional-distsim.tagger -textFile sample-input.txt > sample-tagged.txt
也有類似的錯誤。我甚至通過了Java 2 GB的內存,但仍然沒有運氣。
任何想法/想法或哈克式解決方案非常受歡迎!
好看準@nsanglar,所以我嘗試:
java -Xmx2g -classpath stanford-postagger.jar edu.stanford.nlp.tagger.maxent.MaxentTagger -model models/wsj-0-18-bidirectional-distsim.tagger -textFile raw_text.txt > sample-tagged.txt
我得到一個錯誤日誌消息,與下面的頭:
# There is insufficient memory for the Java Runtime Environment to continue.
# Native memory allocation (malloc) failed to allocate 283639808 bytes for committing reserved memory.
# Possible reasons:
# The system is out of physical RAM or swap space

# Reduce memory load on the system

我從來沒有見過這樣的錯誤日誌,但似乎您試圖分配太多的內存應用程序(例如2go的)。你能少嘗試嗎?試試-Xmx512m或-Xmx1024m,它可能會更好。 – nsanglar 2014-10-20 14:13:37
感謝您的幫助,我按照您的建議做了,並再次得到:異常在線程「主」java.lang.OutOfMemoryError:Java堆空間 – laila 2014-10-20 15:34:26
