Exceptions Running HermiT and Pellet

[Jean]

Hi,

1) I tested the reasoner sync_reasoner() (HermiT) with the code described in "Owlready Documentation" (1.0) "1.8.2 Setting up everything". But, I still get this exception:

UnicodeDecodeError: 'utf-8' codec can't decode byte 0xe7 in position 720: invalid continuation byte
 Has anyone ever solved this problem?

2) I updated Owlready (0.10 > 0.11) and I tested the same code with sync_reasoner_pellet(). Everything worked well, but  in this example ("1.8.4 Results of the automatic classification"), drug1, drug2 and drug3 Classes have not changed!

Thanks for your feedback.
Jean.

Hi,

Ithink those problem might be related to your configuration. Can you give me the version of Python and Java you are using ?

Could you also give me the entire traceback for the UnicodeDecodeError obtained with HermiT ?

Best regards,

Hi,

Here are the versions of Python and Java:

Python 3.6.6 :: Anaconda custom (64-bit)

java version "1.8.0_181"
Java(TM) SE Runtime Environment (build 1.8.0_181-b13)
Java HotSpot(TM) 64-Bit Server VM (build 25.181-b13, mixed mode)

I put a screenshot of the exception in an attached file.

Thanks .

Jean.

Hi,

For HermiT, it seems that HermiT produced some non-UTF8 characters. Is there such character in you classname?

Could you run the reasoner with the keep_tmp_file = 1 option as follows:

    sync_reasoner(keep_tmp_file = 1)

and send me the generated temporary file ? The name of the file appears at the end of the java command line.

Best regards,

- There is no such character type, I used the reasoning example of the "Owlready2 Documentation, Release 0.10". The OS is Win. 10 in Portuguese  

2. I uploaded the requested temporary file. tmpp21wu4w6.tmpp21wu4w6 [the content is quite different online]. The same file with a.txt extension tmpp21wu4w6.txt

Thanks.

Hi,

I think the problem is there:

<http://test.org/onto.owl#clavulanic_acid > <http://www.w3.org/1999/02/22-rdf-syntax-ns#type> <http://www.w3.org/2002/07/owl#NamedIndividual> .

There is a space at the end of "clavulanic_acid", and space is not a valid character in identifiers.

Perhaps you created the individual with a space at the end of its name?

Hi,
Yes, you're right, that's exactly what caused the problem (fig. attached). Now, the reasoner's results match to what is expected.
Thank you.
Jean.
