File not found in wordrank wrapper

[mohammad1234]

I've been trying to train a wordrank model with the provided text8 data with the workrank package using gensim wrapper, but getting No such file or directory error, which is unusual cause I've verified my wordrank installation by running the demo script provided with wordrank package which runs without any issue. Also i checked the permission on the wordrank installation directory, which should not be any problem.

Is that a bug in the gensim package or something i'm missing here ?

test_model = Wordrank.train(wr_path = '/mnt/wordrank', corpus_file = '/mnt/wordrank/scripts/text8', out_path = '/mnt/word_rank_out/', iter=6)

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/local/lib64/python2.7/site-packages/gensim/models/wrappers/wordrank.py", line 105, in train

@mohammad1234 Can you run command from utils.check_output(w, args=command, stdin=r), you need command

@parulsethi Can you please add logging running command before run utils.check_output here

For example

The out_path is actually a directory that is created inside the wordrank directory to save all the meta data and embedding dumps. It has to be at first level in wordrank directory for handling further file creations/processing, ex. it can be word_rank_out/, not /mnt/word_rank_out/ (hence results in the reported error).

I think out_path is a misleading parameter name, out_name could be a better option to indicate just the directory name input. I'll send the PR for this

Fixed in #1332
