    <p>First of all, I'm using Eclipse on MacBook for Java coding. I wrote a Python code that uses NLTK "for natural language processing" and it worked nicely. I tried to call a simple Python code from Java and it also worked as expected.</p> <p><em>BUT when I tried to call the Python code that uses the NLTK, the import statement fails:</em> <strong>"ImportError: No module named nltk"</strong></p> <p>It seems that Python was able to locate the NLTK library, but from Java it couldn't.</p> <p>I tried to have the import statement in both the Python code and the Java code but with no luck.</p> <p><strong>Here is the Python code:</strong></p> <pre><code>#!/usr/local/bin/python # coding: UTF-8 import os, sys from nltk.tokenize import word_tokenize # Tokenizer class RTE: def WordPhraseRate(self, Text): T_tokens = word_tokenize(Text) . . . </code></pre> <p><strong>And Here is the Java Code:</strong></p> <pre><code>import org.python.util.*; import org.python.core.*; import org.python.util.PythonInterpreter; public class NLU_RTE { public PythonInterpreter interpreter = null; public NLU_RTE() { PythonInterpreter.initialize(System.getProperties(), System.getProperties(), new String[0]); this.interpreter = new PythonInterpreter(); } void execfile( final String fileName ) { this.interpreter.execfile(fileName); } PyInstance createClass( final String className, final String opts ) { return (PyInstance) this.interpreter.eval(className + "(" + opts + ")"); } public static void main( String gargs[] ) { NLU_RTE ie = new NLU_RTE(); ie.execfile("/Users/Desktop/nlu.py"); ie.interpreter.exec("from nltk.tokenize import word_tokenize # Tokenizer"); String T="About two weeks before the trial started, I was in Shapiro's office in Century City."; // Text ie.interpreter.set("T", T); PyObject answer = ie.interpreter.eval("RTE('None').WordPhraseRate(T)"); System.out.print(answer.toString()); } } </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
