Error in Python NLTK

[subhabangalore]

Dear Group,

I was using a package named NLTK in Python.

I was trying to write a code given in section 3.8 of

http://docs.huihoo.com/nltk/0.9.5/guides/tag.html.

Here, in the >>> test = ['up', 'down', 'up'] if I put more than 3 values and trying to write the reciprocal codes, like,

sequence = [(t, None) for t in test] and print '%.3f' % (model.probability(sequence))

I am getting an error as,

Traceback (most recent call last): File "", line 1, in model.probability(sequence) File "C:\Python27\lib\site-packages\nltk\tag\hmm.py", line 228, in probability return 2**(self.log_probability(self._transform.transform(sequence))) File "C:\Python27\lib\site-packages\nltk\tag\hmm.py", line 259, in log_probability alpha = self._forward_probability(sequence) File "C:\Python27\lib\site-packages\nltk\tag\hmm.py", line 694, in _forward_probability alpha[0, i] = self._priors.logprob(state) + \ File "C:\Python27\lib\site-packages\nltk\probability.py", line 689, in logprob elif self._prob_dict[sample] == 0: return _NINF ValueError: The truth value of an array with more than one element is ambiguous. Use a.any() or a.all()

If any learned member may kindly assist me how may I solve the issue.

Regards,
Subhabrata.

Dear Group,

This 'and' operator is going to try to interpret the previous list as a
boolean. Could that be your problem? Why aren't you putting these two
statements on separate lines? And what version of Python are you using?
If 2.x, you should get a syntax error because print is a statement.
If 3.x, you should get a different error because you don't put parens
around the preint expression.

I am getting an error as,

Traceback (most recent call last): File "", line 1, in model.probability(sequence) File "C:\Python27\lib\site-packages\nltk\tag\hmm.py", line 228, in probability return 2**(self.log_probability(self._transform.transform(sequence))) File "C:\Python27\lib\site-packages\nltk\tag\hmm.py", line 259, in log_probability alpha = self._forward_probability(sequence) File "C:\Python27\lib\site-packages\nltk\tag\hmm.py", line 694, in _forward_probability alpha[0, i] = self._priors.logprob(state) + \ File "C:\Python27\lib\site-packages\nltk\probability.py", line 689, in logprob elif self._prob_dict[sample] == 0: return _NINF ValueError: The truth value of an array with more than one element is ambiguous.

Your code is also sparse. Why do you point us to fragments on the net,
when you could show us the exact code you were running when it failed?
I'm guessing you're running it from the interpreter, which can be very
confusing once you have to ask for help. Please put a sample of code
into a file, run it, and paste into your text email both the contents of
that file and the full traceback. thanks.
