load model from word2vec:PythonShell-ParseError

[yuetianluo]

Hi~
I have just run the word2vec model by using genesis module and save the model. And I want to call python in my sails app and load the model I have generated. And I got the following error. I have spending so much time on that but still couldn't figure out what's run.
Thanks ahead for your help!

here is my code:
word2vec.py
import collections
import gensim, logging
logging.basicConfig(format='%(asctime)s : %(levelname)s : %(message)s', level=logging.INFO)
model = gensim.models.Word2Vec.load('course_word2vec')

CourseController.js
var PythonShell = require('python-shell');
var courseid=req.param('courseid');
sails.log.debug(coursed);
var options = {
args: [courseid]
};
PythonShell.run('word2vec.py', options, function (err, results) {
if (err) throw err;
console.log('results: %s', results[0]);
});
return res.ok();
and the error is

`/Users/luoyuetian/Desktop/junior/summerproject/course_recommendation_interface/api/controllers/SimilarcourseController.js:41
if (err) throw err;

It looks like this Python script is writing to stderr for logging, which is not unusual. Some programs prefer tracing to stderr to suppress noise from stdout and keep the output clean. However, python-shell sees that as an error and throws whatever was read from stderr.

I see two options:

• Refactor your Python script to prevent it from logging, keeping stderr strictly for normal errors
• Override PythonShell.prototype.parseError to ignore content from stderr, but you will lose detailed error handling such as the Python traceback. PythonShell will still fail if a real error is encountered by reading the exit code.

Thank you so much. There is no error after I remove the logging
