Thanks, good to know, we should deprecate these old readers/writers in
maxent,
I will open a jira for it.

Well, I was not able to fix my problem with the

works fine.
Thanks!

Ahh, you are using the SuffixSensitiveGISModelReader, but is the file you
read the same
as you write, below you write to foo and read from foo.txt.
You can also try to use the BinaryGISModelWriter/Reader, that should work
if its a problem related
to the readers, usually the plain text ones are not used much anymore.

Which model reader do you use to read the model back in?
As far as I see in the code you need to use the PlainTextGISModelReader,
either directly or again via the SuffixSensitiveGISModelReader.
HTH,

Looks like you are getting an IOException while writing the model,
is that correct?
Not while writing the model, but when calling close on the writer (after
the call to persist returned nil). This means that the writer somehow is
already closed during the call to persist I guess? Perhaps there is some
interaction with Clojure's lazyness? (just guessing)
Hello,
we need to have a look at the exception to be able to identify the
problem,
please post it here.

Dear Jörn,
Below you can see a complete trace of my clojure interaction leading up
to
the exception. s you can see, an exception is already thrown when I try
to
close the SuffixSensitiveGISModelWriter. The model is however written to
file. When I try to read that file, the "NumberFormatException" is
thrown.
The input string "my_30" is one of the features on which the classifier
was trained.
