SoxNotInstalled exception raised when importing pyaudioconvert

enter image description hereAs can be seen in the traceback the exception occurs when pyaudioconvert is imported. How can this be fixed?
Traceback below:
Traceback (most recent call last):
File "C:\Users\320052863\PycharmProjects\Test\venv\lib\site-packages\pyaudioconvert\__init__.py", line 43, in <module>

During handling of the above exception, another exception occurred:
Traceback (most recent call last):
File "C:/Users/320052863/PycharmProjects/Test/hello.py", line 1, in <module>

raise SoxNotInstalled()
pyaudioconvert.SoxNotInstalled

As the error message says, you need to install SoX.
It is also listed as a requirement for pyaudioconvert.

Python tests pass on cmd and fail on VS2012

I'm setting up Python (CPython 3.4, 64-bit) on a new machine (Windows 10). I installed numpy & nose, and ran numpy.test() through the interpreter prompt to make sure everything's working as expected:
Running unit tests for numpy

So far so good, but when I do the same thing through PTVS on VS2012 (my team uses TFS for source control), there are errors and test failures (below):

Press any key to continue . . .
I ran the script that I wrote in VS through the command line, and the results were the same as running the test through the interpreter directly, so I'm confident there's something amiss in my VS/Python setup rather than the script itself. What could the problem be?

There's nothing amiss in your setup. It's just that numpy tests seem to be fragile in a sense that they don't tolerate debuggers. I'm not sure what's going on there, but it seems that tests involving sys.getrefcount, and semantics that depend on it being something specifically (usually just having a single reference to an array) are what's failing.
You can repro this when running the interpreter directly by registering your own trace function with sys.settrace, e.g.:
import sys
def trace_func(f, e, a):
return trace_func
sys.settrace(trace_func)
import numpy
numpy.test()
Note that you can run the script from VS without debugging it via Debug -> Start Without Debugging. This will give you results identical to running the interpreter directly.

Memory error in iGraph Python when adding large number of edges

Regarding this thread : http://goo.gl/uEyFua
I am experiencing a quite similar issue with the following code, trying to import a large Graph :
for (edge_id) in cursorSQL:
L.add((edge_id[2], str(edge_id[1])))
g = igraph.Graph.TupleList(L)
I get the following errors :
Traceback (most recent call last):
File "C.py", line 707, in __getitem__ return self._ids[item]
KeyError: '184840900'
During handling of the above exception, another exception occurred:
Traceback (most recent call last):
g = igraph.Graph.TupleList(L)
File "C:\Python34\lib\site-packages\igraph\__init__.py", line 2473, in TupleList
edge_list.append((idgen[item[0]], idgen[item[1]]))
File "C:\Python34\lib\site-packages\igraph\datatypes.py", line 709, in __getitem__
self._ids[item] = next(self._generator)
MemoryError
Just to make it clear. This code works perfectly until number of edges is too large (~4millions.)
Thanks.

Switched to python-64bits, and problem is now solved.
Problem was the 2GB-per-process limit in win7 for python-32bits.
