Problem running modified run_lstm.py locally

[Eoin M]

For my project I need to modify the run_lstm.py script. When I try to run my own modified version locally on one of the (formerly) Appleton Tower macs (PPLS-ATLab-008), I get the following error message.

File “run_lstm.py”, line 18, in <module>
from frontend.label_normalisation import HTSLabelNormalisation, XMLLabelNormalisation
File “/Users/s1205542/dnn_tts/frontend/label_normalisation.py”, line 9, in <module>
from lxml import etree

ImportError: dlopen(/Volumes/Network/courses/ss/dnn/lib/python2.7/site-packages/lxml/etree.so, 2): no suitable image found. Did find:
/Volumes/Network/courses/ss/dnn/lib/python2.7/site-packages/lxml/etree.so: mach-o, but wrong architecture

It seems like running the script involves importing a package which has binary for the wrong architecture.

Is there a way to overcome this on the Appleton Tower machines?

Currently libxml isn’t working on the lab machines. But it’s not needed – comment out all lxml (or modules from lxml) imports. These will be in

frontend/label_composer.py
frontend/label_normalisation.py

Or, if you want to be more future-proof (you might need the libxml functions if you want to integrate with Ossian), wrap the imports in try...except such as

try:
    from lxml import etree
except:
    print "Failed to import etree from lxml"

or

try:
    import lxml
    from lxml import etree
    from lxml.etree import * 
    MODULE_PARSER = etree.XMLParser()
except:
    print "Failed to import lxml"

A similar import problem, during generation, this time for

import bandmat as bm
import bandmat.linalg as bla

in mlpg_fast.py. Is there any way to get this package on the PPLS Macs?

[Simon]

You can take a copy of bandmat from /Volumes/Network/courses/ss/dnn/dnn_tts/bandmat, or add that to your PYTHONPATH
