Synthesis: AttributeError

[Hanzhang X]

I am building a naive system for Jinhua dialect using msc_demo_02 according to msc_ossian_notes.txt. In the last step (synthesis), there is a warning saying:

Traceback (most recent call last):

AttributeError: ‘NNAcousticPredictor’ object has no attribute ‘model’

P.S. When I trained the models, there was a warning message saying:
/usr/lib64/python2.7/site-packages/matplotlib/__init__.py:1173: UserWarning: This call to matplotlib.use() has no effect
because the backend has already been chosen;
matplotlib.use() must be called *before* pylab, matplotlib.pyplot,
or matplotlib.backends is imported for the first time.

warnings.warn(_use_error_msg)

I don’t know whether it matters or not.

The first problem is solved. It turned out that I got the path of the output files wrong.

However, there is still an error message during synthesis:

f = open(outfile, “w”)
IOError: [Errno 13] Permission denied: u’/tmp/tmp.mgc’

I checked the “output” folder, there are files in folder “dnn_lab” and “lab_dur”, but nothing is in “utt” or “wav”.

I did not figure the problem out, but when I ran the scripts again, it worked…
