Re: Beginning question #compilersetup, #windows7, #vs2010
Thanks to both of you for the info. It'll take me a while to dig through
it and make sense of it all.
Today I was able to install visual studio community 2015 for use with
python 3.5. Then I tried using pip to install python-pptx and xlwings. I
believe on xlwings I got the following error (in part) didn't know if the
whole thing would be useful. Thinking about this I'm not sure if this a
compiler issue or a situation where lxml isn't supported in 3.5 yet.
Might someone be able to shed some insight?
Thanks,
Jeff

I don't know of any product named "pywin3.5". There's 'pywin32' (as in 'Python interface to Win32', available from http://pywin32.sourceforge.net/) and Python 3.5 (as in 'CPython 3.5.0 for Windows', available from https://www.python.org/). > even pip is not installed if I run pip its shows like pip command not found. Installing pip is an option in the Python 3.5 (and 3.4, and 2.7.10) installer. If you didn't select it, it won't be installed. You can try running 'python -m ensurepip' to install pip after the main installation of Python. > From which path I have to run this python -m pip install pypiwin32 Doesn't matter; as long as the 'python' command can be found and that Python has pip installed, this command will install pywin32 into the global site-packages directory of that Python. Also, I should have directed you to `py -m pip install pypiwin32` to make use of the Python Launcher, which is always on PATH (if it was installed, it's also an option in the installer). -- Zach -- https://mail.python.org/mailman/listinfo/python-list

Partially invalid sys.path - how can I fix it (not append to it)?
Hi, On a OS/X 101.10.5 (Yosemite) system, the system Python just got updated to 2.7.10 but it sys.path is partially invalid. How can I fix that? I don't want to add something in PYTHONPATH. I know I can create a softlink at the invalid location to where the real files are located.I just want to understand why that sys.path[6] (see below) is invalid and fix it to point to the valid directory. Details follow: I am running Python 2.7.10: [~]$ python Python 2.7.10 (default, Jul 14 2015, 19:46:27) [GCC 4.2.1 Compatible Apple LLVM 6.0 (clang-600.0.39)] on darwin Type "help", "copyright", "credits" or "license" for more information. >>> First, see when I get the sys.path before site.py is imported:: [~]$ python -S -c "import sys, pprint; print sys.prefix; pprint.pprint(sys.path)" /usr ['', '/usr/lib/python27.zip', '/usr/lib/python2.7/', '/usr/lib/python2.7/plat-darwin', '/usr/lib/python2.7/plat-mac', '/usr/lib/python2.7/plat-mac/lib-scriptpackages', '/usr/lib/python2.7/../../Extras/lib/python', '/usr/lib/python2.7/lib-tk', '/usr/lib/python2.7/lib-old', '/usr/lib/python2.7/lib-dynload'] [~]$ python -c "import sys, pprint; print sys.prefix; pprint.pprint(sys.path)" /usr ['', '/usr/lib/python27.zip', '/usr/lib/python2.7', '/usr/lib/python2.7/plat-darwin', '/usr/lib/python2.7/plat-mac', '/usr/lib/python2.7/plat-mac/lib-scriptpackages', '/usr/Extras/lib/python', '/usr/lib/python2.7/lib-tk', '/usr/lib/python2.7/lib-old', '/usr/lib/python2.7/lib-dynload', '/Library/Python/2.7/site-packages'] [~]$ Notice sys.path[6]. It is '/usr/lib/python2.7/../../Extras/lib/python', which when going through site gets normalized to '/usr/Extras/lib/python'. That directory is invalid on my system. It should either be: - The real location: /System/Library/Frameworks/Python.frameworks/Versions/2.7/Extras/lib/python or - the corresponding softlink to that: /usr/lib/python2.7/Extras/lib/python Also note that the sys.prefix is "/usr" I think it should be "/usr/lib/python2.7" or "/System/Library/Frameworks/Python.framework/Versions/2.7" Other Python installed on that system include Python 3.5 (installed via the Python 3.5 DMG installer) and Python 2.7.9 installed with homebrew. For these versions of Python I see something that matches the content of the system storage: - Python 3.5: sys.prefix = '/Library/Frameworks/Python.framework/Versions/3.5' - Python 2.7.9: sys.prefix = '/usr/local/Cellar/python/2.7.9/Frameworks/Python.framework/Versions/2.7' Does anyone know how to fix the path generated in sys.path without adding the real directory path in PYTHONPATH?

I'll also note that step 2) is completely unnecessary in most cases (in fact, I have never set PYTHONPATH on Windows, except where venv did it for me), and in fact is likely to break things if you have more than one version of Python installed. Only set PYTHONPATH once you've determined that it's actually necessary. -- Zach -- https://mail.python.org/mailman/listinfo/python-list
multiprocessing speedup
I am using the multiprocessing with apply_async to do some work. Each task takes a few seconds but I have several thousand tasks. I was wondering if there is a more efficient method and especially when I plan to operate on a large memory arrays (numpy) Here is what I have now import multiprocessing as mp import random def f(x): count=0 for i in range(x): x=random.random() y=random.random() if x*x + y*y<=1: count+=1 return count def main(): resultObj=[] n=1 P=mp.Pool(2) for arg in xrange(n): resultObj.append(P.apply_async(f,(arg,))) P.close() P.join() result = [ i.get() for i in resultObj ] print sum(result)/(n) if __name__=="__main__": main() 1) Does multiprocessing do a fork for each task? 2) If so, I assume thats costly due to setup and teardown. Would this be the case? 3) I plan to pass large arrays to function,f, therefore is there a more efficient method to achieve this? -- --- Get your facts first, then you can distort them as you please.-- -- https://mail.python.org/mailman/listinfo/python-list

You have found out that the execution of "site.py" inserts the invalid entries to "sys.path". I remember that there is a document (it was somewhere on "python.org", when I last read it, but this was years ago) which describes what "site.py" does. In particular, it interprets "*.pth" files it finds via "sys.path" and extends "sys.path" according to the content of those files. I find it quite likely, that one of those "*.pth" files might cause the wrong entry in your "sys.path". > Also note that the sys.prefix is "/usr" > I think it should be "/usr/lib/python2.7" or > "/System/Library/Frameworks/Python.framework/Versions/2.7" I think this is correct: Python expects the directory corresponding to "prefix" to have subdirectories "bin", "lib/python" and "include". -- https://mail.python.org/mailman/listinfo/python-list
