次のテストコードを使用して、IntelliJ IDEA を使用して実行された Jython 2.7.1 から実行された CoreNLP を使用しようとしています。
from edu.stanford.nlp.simple import *
s = Sentence("This is a test.")
ss = s.nerTags()
print(s)
print(ss)

IDE を使用して CoreNLP ディレクトリを CLASSPATH に追加したところ、Jython がそれを見つけられるようです。エラーに関する SO に関するいくつかの同様の質問がありますが、それらの解決策 (もしあれば) は実際には私にとってはうまくいきませんでした。他の誰かがこの問題の解決策を見つけましたか? (記録として、CoreNLP はコマンド ラインから実行すると正常に動作します。)
