Just install Python 2.6 instead of Python 2.7. When i tried with Python 2.7 i got also the same error. Then i removed Python 2.7 and installed Python 2.6. And all worked finely.

I have downloaded Add-on SDK and executed activate. Python 2.7 is installed. PATH variable is configured properly and py files can run from anywhere. However, when i am trying to execute cfx (from Far command prompt, using the full path), i get the message: 'python' is not recognized as an internal or external command. How do i make it run?

I need to record 24-bit audio (because it's the archival standard for audio digitization). However, the wave library seems to only go up to 16-bit. It looks like pyaudio can work with 24-bit audio but every example I've found shows pyaudio using the wave library, meaning it has to save 16-bit. Is it possible to record and playback 24-bit audio with pyaudio?

I have some C# code that needs to call a Python script several thousand times, each time passing a string, and then expecting a float back. The python script can be run using ANY version of Python, so I cannot use Iron python. It's been recommended that I use IPC named pipes. I have no experience with this, and am having trouble figuring out how to do this between C# and Python. Is this a simple process, or am I looking at a decent amount of work? Is this the best way to solve my problem?

If speed is a concern, a good approach would be to choose an EC2 instance fairly close to your S3 bucket (in the same region) and use that instance to unzip/process your zipped files. This will allow for a latency reduction and allow you to process them fairly efficiently. You can remove each extracted file after finishing your work. Note: This will only work if you are fine using EC2 instances.

For 1), if you don't want to do a separate route for every single route on your website, you'll need middleware that implements process_exception and outputs an HttpResponseRedirect. For 2 and 3, those are rules that are presumably limited to specific routes, so you can do them without middleware. 2 might be doable in urls.py with a RedirectView, but since the relevant bit is a query string argument, I would probably make that an actual view function that looks at the query string. Putting a ? character in a url regex seems strange because it will interfere with any other use of query strings on that endpoint, among other reasons. For 3, that's a straightforward RedirectView and you can do it entirely in urls.py.

Need a little help with my urls.py and other stuff. How can I replicate this in Django? 1) When user requests a non-existent page it will redirect to one up the directory level. Ex: example.com/somegoodpage/somebadpage should be redirected to example.com/somegoodpage. 2) When user requests page example.com/foo/bar/?name=John it will make url to example.com/foo/bar/name=John 3) When user requests page example.com/foo/bar/John it will change url to example.com/foo/bar/name=John. Any help is greatly appreciated. Thank You.

if your using applescript, just save it as a bundle by save as, and click the drop down saying script, change that to bundle i think. after that, click on the bundle icon in apple script and drag the script to the folder you want. to run it put your run command in and drag the script that you placed in the bundle folders before in the directory slot of the run command. i can not give you anything exact due to the fact that i am not on my mac, but i am giving you the best i know.

I have a script (Shell, chmod-ed to 755. Python is in the script, meaning not run from an outside .py file) that is executable. It works when I run it. How can I make a .app that executes said script on runtime? I have a simple .app that has this structure: APPNAME.App>Contents>MacOS>script This does not run. Is there any way I can piggyback a script onto another application, The Powder Toy, for example? I'm not new to OSX, I just don't have root privileges and can't install XCode.

If your server is does not receive packets often, it will not improve much - only gain some tiny overhead on inter server communication. Still it is a very good design idea, because it scales well and once you finally get many packets you will just add an instance of data processing server.

I am developing a tcp/ip server whose purpose is receive packets from client, parse them, do some computation(on data arriving in packet) and store it in database. Till now, everything was being done by single server application written using twisted python. Now I am across RabbitMQ so my question is, if it is possible and if it will lead to better performance if my twisted server application just receives the packets from clients and pass it another c++ application using RabbitMQ. The c++ application will in turn parse packets, do computation on it etc.. Everything will be done on single server.

PyCharm does not check the syntax inside strings and comments. It checks spelling. You can find the settings of the spell-checker under the Settings... page. There is a Spelling page inside Project Settings. Inside this page, at the bottom of the Dictionaries tab you can enable/disable dictionaries. If you don't want spell checking simply disable all of them. Note that it is possible to add custom words in the spell checker, or, if you already have a dictionary on your computer, you can add it. This can turn out useful if you want to spell check different languages (for example Italian). In particular if you are using a Linux system and you have installed the Italian language pack, you probably have the Italian dictionary under: /usr/share/dict/italian. You can add the /usr/share/dict directory to the directories searched for dictionaries and enable the italian dictionary. It seems like PyCharm only checks files with the .dic extension. If you want to use /usr/share/dict/italian you should probably either copy it into an other directory renaming it italian.dic or you could create a symbolic link.

I am trying to deploy my django on a server, but this server has an extra tag for the url like this. http://john.example.com/mywebsite instead of http://john.example.com so whenever I want to redirect from the homepage to other pages, I got error messages because the redirected pages are missing the extra tag /mywebsite for example I want to direct to http://john.example.com/mywebsite/apple but when I choose on link on the template it direct me to http://john.example.com/apple so I just wonder if there is a way to fix this by setting default home directory to http://john.example.com/mywebsite instead of http://john.example.com/ so I don't have to fix all my code Thanks you

Yes you can do this, but mostly people do multiple blocking sockets with threads or multiple non-blocking sockets with event loops. But it should be no problem in switching in-between, as long as you don't switch between buffered and unbuffered I/O.

I would like to start the conversation in blocking mode and later switch to non-blocking. Is that a stupid idea? The python docs are kind of ambiguous about it, there it says: ... You do this [setblocking(0)] after creating the socket, but before using it. (Actually, if you’re nuts, you can switch back and forth.) I read this as 'please don't do that', so I was wondering if there are reasons as to why it is discouraged. Is there some kind of undefined behavior, what problems could I run into?

You will need to do this in several steps (at least in Python - .NET languages can use a regex engine that has more capabilities): First, match a part of a string starting with not, no or never. The regex \b(?:not?|never)\b([^.,:;!?]+) would be a good starting point. You might need to add more punctuation characters to that list if they occur in your texts. Then, use the match result's group 1 as the target of your second step: Find all words (for example by splitting on whitespace and/or punctuation) and prepend NEG_ to them. Join the string together again and insert the result in your original string in the place of the first regex's match.

You can think of it this way: "Duck Typing" applies to the type of a variable, not of the variable's contents. A string variable is something that can for example be indexed with [] or added to other strings with + and even repeated several times with * {some integer}, but you can't add a string to an integer, even if the string happens to be a number. The number-ness of a string has nothing to do with the type.

I'm new to using Python (and dynamically typed languages in general) and I'm having trouble with the my variables being incorrectly-typed at run time. The program I've written accepts 6 variables (all should be integers) and performs a series of calculations using them. However, the interpreter refuses to perform the first multiplication because it believes the variables are type 'str'. Even when I enter integers for all values it breaks at run-time and claims I've entered strings. Shouldn't Python treat anything that walks and quacks like an int as if it were an int? Thanks in advance. PS: I'm running Python 3.4.0, if that helps.

I'm trying to use the data collected by a form I to a sqlite query. In this form I've made a spin button which gets any numeric input (ie. either2,34 or 2.34) and sends it in the form of 2,34 which python sees as str. I've already tried to float() the value but it doesn't work. It seems to be a locale problem but somehow locale.setlocale(locale.LC_ALL, '') is unsupported (says WinXP). All these happen even though I haven't set anything to greek (language, locale, etc) but somehow Windows does its magic. Can someone help? PS: Of course my script starts with # -*- coding: utf-8 -*- so as to have anything in greek (even comments) in the code.

Yes, potentially you might want to skip the immediate superclass method, but still call the methods further up the hierarchy. This might happen for example when you know you have replaced the logic with your own, and calling the superclass method would be pointless or even harmful.

I know that in Python 3, you can write super() and Python automatically passes the correct arguments to super. It's also possible to introduce subtle bugs by accidentally writing super(Parent, self). Are there any scenarios where you wouldn't want to pass the current class as the first argument to super?

Would you ever pass anything other than (MyClass, self) to super()?

The principled way to do this is to assign probabilities to different model types and to different parameters within a model type. Look for "Bayesian model estimation".

My problem is as follows: I am given a number of chi-squared values for the same collection of data sets, fitted with different models. (so, for example, for 5 collections of points, fitted with either a single binomial distribution, or both binomial and normal distributions, I would have 10 chi-squared values). I would like to use machine learning categorization to categorize the data sets into "models": e.g. data sets (1,2,5 and 7) are best fitted using only binomial distributions, whereas sets (3,4,6,8,9,10) - using normal distribution as well. Notably, the number of degrees of freedom is likely to be different for both chi-squared distributions and is always known, as is the number of models. My (probably) naive guess for a solution would be as follows: Randomly distribute the points (10 chi-squared values in this case) into the number of categories (2). Fit each of the categories using the particular chi-squared distributions (in this case with different numbers of degrees of freedom) Move outlying points from one distribution to the next. Repeat steps 2 and 3 until happy with result. However I don't know how I would select the outlying points, or, for that matter, if there already is an algorithm that does it. I am extremely new to machine learning and fairly new to statistics, so any relevant keywords would be appreciated too.

The scoped session manager will by default return the same session object for each connection. Accordingly, one can replace .commit with .flush, and have that change persist across invocations to the session manager. That will prevent commits. To then rollback all changes, one should use session.transaction.rollback().

I'm using fixtures with SQLAlchemy to create some integration tests. I'd like to put SQLAlchemy into a "never commit" mode to prevent changes ever being written to the database, so that my tests are completely isolated from each other. Is there a way to do this? My initial thoughts are that perhaps I could replace Session.commit with a mock object; however I'm not sure if there are other things that might have the same effect that I also need to mock if I'm going to go down that route.

the "report generating" methods of dircmp.filecmp don't accept a file object, they just use the print statement (or, in the Python 3 version, the print() function) You could create a subclass of dircmp.filecmp which accepts a file argument to methods report, report_full_closure and report_partial_closure (if needed), at each print ... site writing print >>dest, .... Where report_*_closure call recursively, pass the dest argument down to the recursive call. The lack of ability to print output to a specific file seems to me to be an oversight, so having added an optional file argument to these methods and tested it thoroughly you may wish to offer your contribution to the Python project. If your program is single threaded, you could temporarily replace sys.stdout with your destination file before calling the report methods. But this is a dirty and fragile method, and it is probably foolish to imagine your program will be forever single threaded.

I'd like to output a series of dircmp report_full_disclosure()'s to a text file. However the report_full_disclosure() format is one blob of text, it doesn't play nicely with file.write(comparison_object.report_full_disclosure()) because file.write() expects a single line to write to the file. I've tried iterating through the report_full_disclosure() report but it doesn't work either. Has anyone else had this particular problem before? Is there a different method to write out to files?

How do write filecmp's report_full_disclosure() to a text file?

In short "you cannot". This task is far beyond simple text processing which is provided with NLTK. Such objects relations sentiment analysis could be the topic of the research paper, not something solvable with a simple approach. One possible method would be to perform a grammar analysis, extraction of the conceptual relation between objects and then independent sentiment analysis of words included, but as I said before - it is rather a reasearch topic.

I'm using NLTK to extract named entities and I'm wondering how it would be possible to determine the sentiment between entities in the same sentence. So for example for "Jon loves Paris." i would get two entities Jon and Paris. How would I be able to determine the sentiment between these two entities? In this case should be something like Jon -> Paris = positive

I guess it depends on how deep down the rabbit hole you want to go. If you're building a test for the functional side from the user's perspective, and your GET action results in changes on the webpage, then trigger the submit with selenium, then wait for the changes to propagate to the webpage (like waiting for one/more elements to change value or waiting for an element to appear) If you want to build an unit test, then all you should be testing is the ability to Submit the data, not also the ability of the javascript code to do a POST request, then a GET then display the data. If you want to build an integration test, then you will need to check that each individual action in the sequence you described is performed correctly in whatever scenario you deem appropriate and then check that the total result of those actions is as expected. The tricky part will be chaining all those checks together. If you want to build an end to end test, then you need to check for all of the above, plus changes to any permanent storage locations that the code you test changes (like databases or in-memory structures) plus whatever stress/security/usability/performance checks your software needs to pass in your specific context.

I'm using Selenium (python bindings, with Django) for automated web app testing. My page has a form with a button, and the button has a .click() handler that captures the click (i.e. the form is not immediately submitted). The handler runs function2(), and when function2() is done, it submits the form. In my test with Selenium, I fill in the form, then click the Submit button. I want to verify that the form is eventually submitted (resulting in a POST request). The form POSTs and then redirects with GET to the same url, so I can't check for a new url. I think I need to check that the POST request occurs. How do I check for successful form submission? Alternatively I could check at the database level to see that some new object is created, but that would make for a bad "unit" test.

How to detect POST after form submit in Selenium python?

I am pulling the answer out of the comments. Point your PATH system variable to the correct version of Python. This is accomplished (on Windows) by going to System Properties -> Advanced -> Environment Variables. If you already have a Python directory in there, modify it to the correct, new path. Otherwise, append it to the end of the existing string. Do not remove what is already present.

As Pawel said, IronPython uses a complex build system to handle all of the platforms it supports and make it easy-ish to add new ones (at least until IronPython and the DLR can be refactored into portable libraries ... sometime around 2016). In this case you need to dig through a couple of levels of imports to find where it's defined (Build/Common.proj). The reason this happen is that even though the Reference is conditional (and handled correctly) in MSBuild, VS ignores the conditional check and displays any Reference elements it finds. Moving the Reference into Build/net35.props instead should fix the display, since VS does a much better job of handling imports.

I am building ironpython3 with Visual Studio 2013. In the references Visual Studio shows a yellow triangle on Microsoft.Scripting.Core reference. Since I read this reference has been moved to System.Core I simply removed the reference to Microsoft.Scripting.Core. The project builds just fine without this reference. But after ending Visual Studio and opening the project again, the reference is just back. I removed all references I found (Strg-Shift-F) from the sources, but still no change. I had a look in the .csproj file but did not find any references there. I simply cannot remove the reference permanently. Any ideas where to look to permanently remove the reference? Thank you.

There are a couple of approaches. The first is to just create all of the panels that you need and hide them as you've been doing. Another approach would be to create the sizers with the widgets laid out appropriately and just hide the sizers as needed. This way you would only ever have one or two panels, but different layouts.

I do not have any code to show with this question because I am just seeking advice. I have a functional piece of code and through the execution of which I create approx 20 - 30 unique panels. I only use one at any given time (with a few small exceptions) and I use show/hide to manage which panels are displayed at a given time. My question is this: Is it best that I create all 30 panels at the inception point of the code, hide the 29 that are not needed and move on, and then show/hide between the 30 panels as the code runs, or should I only create the one or two that are needed at the start and create the others as they are called for and then hide/destroy the ones that have served their purpose.

wxpython create multiple panels at start or as the program progresses

You can call QApplication::setStyle("windows") before creating QApplication object to set a style by name. However, Qt on Linux is usually built without modern Windows styles, so it's possible that the best you will accomplish is the classic (old) Windows style, which is not very attractive. You can also try to use "fusion" style or other values that QStyleFactory::keys() returns.

I finally managed to write a little app that reads from a sqlite database and show the results to a treeview. Another form (in another module) gives the ability to write new or update existing records. After writing to the database it closes the window What I'm trying to do now is to update the "main" window (containing the treeview) to show the new dataset. I have managed so far to do this but a) the initial mainwindow stays there while a new instance of it opens on top of it showing the desired (new) dataset. How would I make this work? Can someone give me suggestions/example? Perhaps I need to say that the __init__ function of my mainwindow module does everything upon running: creates the gui, reads from the database and show all. I suspect that this may be the problem but having tryed almost any combination of breaking it into pieces (functions), I had no success --EDIT-- OK I have many different functions __init__ now creates the main gui while others read the data from the DB and place it on a treeview. I tried to use a timer but also this option doesn't seem to be apropriate as gtk.TreeView doesn't have such a method.

It is possible that you have already thought of this and have decided against it, but it would obviously run far better in real time if the polygons were pre-drawn. Presuming there aren't very many different types of polygons, you could even resize them however you need and you would be saving CPU. Also, assuming that all of the polygons are regular, you could just have several different equilateral triangles with gradients going in various directions on them to produce the necessary shapes. Another thing you could do is define the polygon you are drawing, than draw an image of a gradient saved on your computer inside that shape. The final thing you could do is to build your program (or certain, CPU intensive parts of your program) in C or C++. Being compiled and automatically optimized during compiling, these languages are significantly faster than python and better suited to what you are trying to do.

I have a scene, and I need to be able to overlay the scene with translucent polygons (which can be done easily using pygame.gfxdraw.filled_polygon which supports drawing with alpha), but the catch is that the amount of translucency has to fade over a distance (so for example, if the alpha value is 255 at one end of the polygon, then it is 0 at the other end and it blends from 255 to 0 through the polygon). I've implemented drawing shapes with gradients by drawing the gradient and then drawing a mask on top, but I've never come across a situation like this, so I have no clue what to do. I need a solution that can run in real time. Does anyone have any ideas?

If this function doesn't exist it would be a huge drawback for me... Because for my data analysis I very often only need to run the last few lines of my code.

Than you very much! I have fixed it! If somebody will have the same problem you must change OnDelete code (The first code in question) for this: def OnDelete(self, event): sel = self.listbox.GetSelection() f = open("Save/savegame.txt", "r") read = f.readlines() f.close() name = self.listbox.GetStringSelection() newfile = """""" for i in read: if name in i: pass else: newfile += i n = open("Save/savegame.txt", "w") one = str(newfile) n.write(one) n.close self.listbox.Delete(sel)

I have very complicated problem. I´ve search whole internet and tried everything, but nothing worked. I want get string from listbox and than delete line in file with word from listbox. Can please somebody help me? Here is code: def OnDelete(self, event): sel = self.listbox.GetSelection() if sel != -1: self.listbox.Delete(sel) subor = open("Save/savegame.txt", "r") lines = subor.readlines() subor.close() subor = open("Save/savegame.txt", "w") selstring = self.listbox.GetString(self.listbox.GetSelection()) for line in lines: if line!=selstring: subor.write(line) subor.close() And this is code for saving file: def OnNewGame(self,event): nameofplr = wx.GetTextFromUser('Enter your name:', 'NEW GAME') subor=open("Save/savegame.txt","a") subor.write( "\n" + nameofplr) subor.close() savegame=open("Save/" + nameofplr + ".prjct", "w+") savegame.close() It shows this error: Traceback (most recent call last): File "D:\Python\Python Projects\Project\Project.py", line 106, in OnDelete selstring = self.listbox.GetString(self.listbox.GetSelection()) File "D:\Python\lib\site-packages\wx-3.0-msw\wx_core.py", line 12962, in GetString return core.ItemContainer_GetString(*args, **kwargs) wx._core.PyAssertionError: C++ assertion "IsValid(n)" failed at ....\src\msw\listbox.cpp(387) in wxListBox::GetString(): invalid index in wxListBox::GetString Thank you very much for help!

You shouldn't be able to bind more than once to the same port number, either from the same process or another. ZMQ should give a failure when you issue bind with a port number already in use. Are you checking return codes?

I have a ZMQ server listening on port 12345 TCP. When another server connects on that port locally or via VM it works fine, but if I try from a remote server that has to go through port forwarding on my Fios firewall it just bombs. The packets are showing up in Wireshark but ZMQ just ignores them. Is there anyway to get past this?

As stated by Guntram Blohm, it is not possible to delete object classes on existing objects because doing that would invalidate the schema checks that the server did when creating the object. So the way to do it will be to delete the object and create a new one. This is a property of the server and the client libraries cannot do anything about it.

When I generated a modlist with modlist.modifyModlist({'objectClass':'inetLocalMailRecipient},{'objectClass' : ''}) , it just generates (1, 'objectClass', None) which obviously doesn't seem correct.

Your solution is really going to be specific to each website page you want to scrape, so, without knowing the websites of interest, the only thing I could really suggest would be to inspect the page source of each page you want to scrape and look if the article is contained in some html element with a specific attribute (either a unique class, id, or even summary attribute) and then use beautiful soup to get the inner html text from that element

I have built a program for summarization that utilizes a parser to parse from multiple websites at a time. I extract only <p> in each article.

Best practice is to never do this kind of thing. If you are giving sudo access to your pi from internet and then executing user input you are giving everyone in the internet the possibility of executing arbitrary commands in your system. I understand that this is probably your pet project, but still imagine someone getting access to your computer and turning camera when you don't really expect it.

I have created a web-app using Python Flask framework on Raspberry Pi running Raspbian. I want to control the hardware and trigger some sudo tasks on the Pi through web. The Flask based server runs in non-sudo mode listening to port 8080. When a web client sends request through HTTP, I want to start a subprocess with sudo privileges. (for ex. trigger changes on gpio pins, turn on camera etc.). What is the best practice for implementing this kind of behavior? The webserver can ask for sudo password to the client, which can be used to raise the privileges. I want some pointers on how to achieve this.

I'd suggest you to use composition instead of inheritance. Then you design class's interface and decide which methods are available.

I am making a programming framework (based on Django) that is intended for students with limited programming experience. Students are supposed to inherit from my base classes (which themselves are inherited from Django models, forms, and views). I am testing this out now with some students, and the problem is that when they write code in their IDE (most of them are using PyCharm), autocomplete gives them a ton of suggestions, since there are so many inherited methods and attributes, 90% of which are not relevant to them. Is there some way to hide these inherited members? At the moment I am primarily thinking of how to hide them in auto-complete (in PyCharm and other IDEs). They can (and probably should) still work if called, but just not show up in places like auto-complete. I tried setting __dict__, but that did not affect what showed up in autocomplete. Another idea I have is to use composition instead of inheritance, though I would have to think this through in more detail. Edit: This framework is not being used in CS classes; rather, students will be using it to build apps for non-CS domain. So my priority is to keep it simple as possible, perhaps even if it's not a "pure" approach. (Nevertheless, I am considering those arguments as they do have merit.)

In Python, can I hide a base class's members?

There's no hard limit to the number of iterations for LogisticRegression; instead it tries to detect convergence with a specified tolerance, tol: the smaller tol, the longer the algorithm will run. From the source code, I gather that the algorithms stops when the norm of the objective's gradient is less than tol times its initial value, before training started. This is worth documenting. As for random forests, training stops when n_estimators trees have been fit of maximum depth max_depth, constrained by the parameters min_samples_split, min_samples_leaf and max_leaf_nodes. Tree learning is completely different from iterative linear model learning.

No, the PyObjects don't generate code -- it is just a c struct that holds the information of that particular Python object. You can inspect them in your C++ debugger. I'm experienced with py embedding. The docs seem clear. Don't really get what your problem is.

I'm publishing a few Python packages internally and I would like to include API documentation, currently in .rst form, but might go for Sphinx-generated HTML in the future. I need more details than I can reasonably put into a docstring (background info, tutorial examples, etc), so I've written it out long-hand. I have a simple distutils-based setup.py where I pull in the text files, but I'm not sure where to put them on the target system (I target Windows, Linux and Mac.) Is there a convention in the Python world for installing API docs alongside packages? Or are docs generally assumed to only be available online? Any ideas welcome, thanks!

This is something you should fix at the web application level, not at the Mercurial level. If you're fine with having people wait you set up a distributed locking scheme where the web worker thread tries to acquire a repository-specific lock from shared memory/storage before taking any actions. If it can't acquire the lock you respond with either a status-code 503 with a retry-after header or you have the web-worker thread retry until it can get the lock or times out.

Our Django project provides interfaces to users to create repository create new repo add new changes to existing repo Any user can access any repo to make changes directly via an HTTP POST containing changes. Its totally fine if the traffic is less. But if the traffic increases up to the point that multiple users want to add changes to same repo at exactly same time, how to handle it?

I have a bunch of clients connecting to a server via 0MQ. I have a Manager queue used for a pool of workers to communicate back to the main process on each client machine. On just one client machine having 250 worker processes, I see a bunch of EOFError's almost instantly. They occur at the point that the put() is being performed. I would expect that a lot of communication might slow everything down, but that I should never see EOFError's in internal multiprocessing logic. I'm not using gevent or anything that might break standard socket functionality. Any thoughts on what could make puts to a Manager queue start raising EOFError's?

The underlying file handle generated when opening a file can be used for reading at one point of the file only. You cannot read multiple offset with the same file handle. So you should use one thread reading the file while other threads read a kind of queue generated by the first thread with the file buffers.

Not the answer you expected, but i have been down that road and advise KISS: First make it work in the most simple way possible. Only than look into speeding things up later / complicating the design. There are lots of other ways to phrase this such as "do not fix hypothetical problems unless resources are unlimited".

Use the ecosystem. For matrices, using numpy and scipy can provide approximately the same range of functionality as tools like Matlab. If you learn to write idiomatic code with these modules, the inner loops can take place in the C or FORTRAN implementations of the modules, resulting in C-like overall performance with Python expressiveness for most tasks. You may also be interested in numexpr, which can further accelerate and in some cases parallelize numpy/scipy expressions. If you must write compute-intensive inner loops in Python, think hard about it first. Maybe you can reformulate the problem in a way more suited to numpy/scipy. Or, maybe you can use data structures available in Python to come up with a better algorithm rather than a faster implementation of the same algorithm. If not, there’s Cython, which uses a restricted subset of Python to compile to machine code. Only as a last resort, and after profiling to identify the absolute worst bottlenecks, should you consider writing an extension module in C/C++. There are just so many easier ways to meet the vast majority of performance requirements, and numeric/mathematical code is an area with very good existing library support.

cython support for c++ is much better than what it was. You can use most of the standard library in cython seamlessly. There are up to 500x speedups in the extreme best case. My experience is that it is best to keep the cython code extremely thin, and forward all arguments to c++. It is much easier to debug c++ directly, and the syntax is better understood. Having to maintain a code base unnecessarily in three different languages is a pain. Using c++/cython means that you have to spend a little time thinking about ownership issues. I.e. it is often safest not to allocate anything in c++ but prepare the memory in python / cython. (Use array.array or numpy.array). Alternatively, make a c++ object wrapped in cython which has a deallocation function. All this means that your application will be more fragile than if it is written only in python or c++: You are abandoning both RAII / gc. On the other hand, your python code should translate line for line into modern c++. So this reminds you not to use old fashioned new or delete etc in your new c++ code but make things fast and clean by keeping the abstractions at a high level. Remember too to re-examine the assumptions behind your original algorithmic choices. What is sensible for python might be foolish for c++. Finally, python makes everything significantly simpler and cleaner and faster to debug than c++. But in many ways, c++ encourages more powerful abstractions and better separation of concerns. When you programme with python and cython and c++, it slowly comes to feel like taking the worse bits of both approaches. It might be worth biting the bullet and rewriting completely in c++. You can keep the python test harness and use the original design as a prototype / testbed.

I realise this question may already exist, but the answers I've found haven't worked and I have a slightly different setup.

Obviously one solution would be to give these resources absolute paths, but the python program also calls other python programs in its directory that also have relative paths, and I don't want to go changing all them.

Rather than change your current working directory, in yourfrontend.pyscript you could use the value of the predefined__file__module attribute, which will be the absolute pathname of the script file, to determine absolute paths to the other files in the same directory. Functions in theos.pathmodule, such assplit()andjoin(), will make doing this fairly easy.

Only an uncaught exception will terminate a program. If you raise an exception that your 3rd-party software is not prepared to catch and handle, the program will terminate. Raising an exception is like a soft abort: you don't know how to handle the error, but you give anyone using your code the opportunity to do so rather than just calling sys.exit(). If you are not prepared for the program to exit, don't raise an exception. Just log the error instead.

Does invoking a raise statement in python cause the program to exit with traceback or continue the program from next statement? I want to raise an exception but continue with the remainder program. Well I need this because I am running the program in a thirdparty system and I want the exception to be thrown yet continue with the program. The concerned code is a threaded function which has to return . Cant I spawn a new thread just for throwing exception and letting the program continue?

Does raising a manual exception in a python program terminate it?

apt-get update updates packages from Ubuntu package catalog, which has nothing to do with mainstream versions. LTS in Ubuntu stands for Long Term Support. Which means that after a certain period in time they will only release security-related bugfixes to the packages. In general, major version of packages will not change inside of a major Ubuntu release, to make sure backwards-compatibility is kept. So if then only thing you can do is apt-get update, you have 2 options: find a PPA that provides fresher versions of packages that you need, add it and repeat the update/install exercise find those packages elsewhere, download them in .deb format and install.

I'm trying to install pip and virtualenv on a server (running Ubuntu 12.04.4 LTS) on which I have access, but I can only do it with sudo apt-get install (school politics). The problem is that althought I have run the sudo apt-get update command to update the packages list, I think it keeps installing old ones. After doing sudo apt-get install python-pip python-virtualenv, I do pip --version on which I get the 1.0, and virtualenv --version on which I get 1.7.1.2. These two version are quite old (pip is already in 1.5.5 and virtualenv in 1.11.5). I read that the problem is that the packages list is not up-to-date, but the command sudo apt-get update should solve this, but I guess no. How can I solve this? Thanks a lot!

It looks like your application is using zmq to bind to some port. As you have suspected already, each request can be run as independent process, thus competing in access to the port to bind to. There can be so called workers, each running one process processing http/wsgi requests, and each trying to bind. You shall redesign your app not to use bind, but connect, this will probably require having another process with zeromq serving something you do with that (but this last line is dependent on what you do in your app).

I have a python web application running on apache2 deployed with mod_wsgi. The application has a thread continuously running. This thread is a ZeroMQ thread and listening to a port in loop. The application is not maintaining session. Now if I open the browser and sends a request to the apache server the data is accepted for the first time. Now when second time I send the request It shows Internal server error. When I checked the error log file for traceback, It shows the ZMQError:- The address already in use. Does apache reloads the application on each request sent from the browser since so that the ZeroMQ thread is being created everytime and being assigned the port but since the port has already been assigned it shows error....

How does apache runs a application when a request comes in?

Approach #3: Compute the QR decomposition of AT In general, to find an orthogonal basis of the range space of some matrix X, one can compute the QR decomposition of this matrix (using Givens rotations or Householder reflectors). Q is an orthogonal matrix and R upper triangular. The columns of Q corresponding to non-zero diagonal entries of R form an orthonormal basis of the range space. If the columns of X=AT, i.e., the rows of A, already are orthogonal, then the QR decomposition will necessarily have the R factor diagonal, where the diagonal entries are plus or minus the lengths of the columns of X resp. the rows of A. Common folklore has it that this approach is numerically better behaved than the computation of the product A*AT=RT*R. This may only matter for larger matrices. The computation is not as straightforward as the matrix product, however, the amount of operations is of the same size.

I can test the rank of a matrix using np.linalg.matrix_rank(A) . But how can I test if all the rows of A are orthogonal efficiently? I could take all pairs of rows and compute the inner product between them but is there a better way? My matrix has fewer rows than columns and the rows are not unit vectors.

I've decided it would be better if I still do the HTTP request, but depending on what the request returned, I could have the client send a packet to the server telling it to give the specific user a notification. For example, if I tried adding user ID #323095643, I send the HTTP request and everything turns out okay and I get an OK response, the flash client sends a packet to the server basically saying "Hey, give user ID #323095643 a notification saying '_ wants you to be their friend'" and it sends it to that user.

I'm working on a game that allows you to add other users as your friend. The game is in Flash AS2 and the server is Python. I'm currently hoping to make it so the game sends an HTTP request to an API server that will then verify everything, such as if they're already friends, if they can be friends, etc, and then if everything's okay, I'd then insert the request into a request able. Anyway, if the user is currently online, I would like to send the user a notification through the server. The only way I could see this happening is if I opened up a socket connection through the add friend script and then sent a special packet letting the server know that it needs to send the notification. Right now that seems like it would take a while to do and not so efficient if a lot of users used it daily. How would I best approach this and is there any other efficient ways?

One way to do it is the append the new data at the end of the existing file. If you catch an error , delete all that you appended. If no errors, delete everything that you had before appending so the new file will have only the appended data. Create a copy of your file before starting capturing the data in a new file.

Any attempt to restore on error will be fragile; what if your program can't continue or encounters another error when attempting to restore the data? A better solution would be to not replace the original file until you know that whatever you're doing succeeded. Write whatever you need to to a temporary file, then when you're ready, replace the original with the temporary.

If you are using logrotate for log rotation then it has options to remove old files, if not you could run something as simple as this once a day in your cron: find /path/to/log/folder -mtime +5 -type f -exec rm {} \; Or more specific match a pattern in the filename find . -mtime +5 -type f -name *.log -exec ls -l {} \; Why not set up logrotate for syslog to rotate daily then use its options to remove anything older than 5 days. Other options involve parsing log file and keeping certain aspect etc removing other bits etc which involved writing to another file and back etc and when it comes to live log files this can end up causing other issues such as a requirement to restart service to relog back into files. so best option would be logrotate for the syslog

I'm running into a few issues on my Emacs + Org mode + Python setup. I thought I'd put this out there to see if the community had any suggestions. Virtualenv: I'm trying to execute a python script within a SRC block using a virtual environment instead of my system's python implementation. I have a number of libraries in this virtual environment that I don't have on my system's python (e.g. Matplotlib). Now, I set python-shell-virtualenv-path to my virtualenv's root directory. When I run M-x run-python the shell runs from my virtual environment. That is, I can import Matplotlib with no problems. But when I import Matplotlib within a SRC block I get an import error. How can I have it so the SRC block uses the python in my virtual environment and not my system's python? Is there any way I can set the path to a given virtual environment automatically when I load an org file? HTML5 Export: I'm trying to export my org-files in 'html5', as opposed to the default 'xhtml-strict'. The manual says to set org-html-html5-fancy to t. I tried searching for org-html-html5-fancy in M-x org-customize but I couldn't find it. I tried adding (setq org-html-html5-fancy t) to my init.el, but nothing happened. I'm not at all proficient in emacs-lisp so my syntax may be wrong. The manual also says I can set html5-fancy in an options line. I'm not really sure how to do this. I tried #+OPTIONS html5-fancy: t but it didn't do anything. How can I export to 'html5' instead of 'xhtml-strict' in org version 7.9.3f and Emacs version 24.3.1? Is there any way I can view and customize the back-end that parses the org file to produce the html? I appreciate any help you can offer.

If you will only ever have one connection, you can call IOLoop.current().stop() from your WebSocketHandler's on_close method. If you need more than one you can increment a counter in open(), decrement it in on_close(), and stop the IOLoop when it reaches zero.

If by ssh you mean actually running the ssh process, try tornado.process.Subprocess. If you want something more integrated into the server, twisted has an asynchronous ssh implementation. If you're using something like paramiko, threads are probably your best bet.

Scenario: My server/application needs to handle multiple concurrent requests and for each request the server opens an ssh link to another m/c, runs a long command and sends the result back. 1 HTTP request comes → server starts 1 SSH connection → waits long time → sends back the SSH result as HTTP response This should happen simultaneously for > 200 HTTP and SSH connections in real time. Solution: The server just has to do one task, that is, open an SSH connection for each HTTP request and keep the connection open. I can't even write the code in an asynchronous way as there is just one task to do: SSH. IOLoop will get blocked for each request. Callback and deferred functions don't provide an advantage as the ssh task runs for a long time. Threading sounds the only way out with event driven technique. I have been going through tornado examples in Python but none suit my particular need: tornado with twisted gevent/eventlet pseudo multithreading python threads established HTTP servers like Apache Environment: Ubuntu 12.04, high RAM & net speed Note: I am bound to use python for coding and please be limited to my scenario only. Opening up multiple SSH links while keeping HTTP connections open sounds all asynch work but I want it to look like a synchronous activity.

This is not a question about Django REST, but about Django itself. The problem with extending the User object directly is that it is already a concrete model, so extending it will use multi-table inheritance. That's not usually a good idea - especially if you're further extending it. AbstractUser is an abstract model, but (unlike AbatractBaseUser) contains all the fields that User defines. You should use that.

I am using Django REST to create users for my app. Everywhere i look at, for users they extend AbstractBaseUser. I tried extending the User model, and it seems to work just fine. I have an PersonalAbstractUser that extends the Django User. Then, Worker and Client extends PersonalAbstractUser. Login and custom permissions seem to work just fine up until now, but i am getting concerned when i see that no one else is extending User... Why is that? Did i miss something?

This is not really suited for StackOveflow; but the suggestion I would make is to take the parts of your code that are subject to audit; write them as a Python C module which is then imported. You can ship the compiled module along with your normal, unmodified django application. This would only work if certain parts of your code are subject to this audit/restriction and not the entire application. Your only other recourse is to host it yourself and provide your own audit/controls on the source.

Here's the deal: I have a Python application for business written in Django. It's not in Cloud, customers should install them at their own servers. However, Brazil IT laws for tax payment calculation softwares forces me to homologate every piece of code (in this case, every file.py). They generate a MD5 hash and if a customer of mine is running a modified version, I have to pay a fine and should even be sued by Government. I really don't care if my source code is available to everyone. Really. I just want to guarantee no changes at the source code. Does anyone have an idea to protect the code? Customers should have root access to servers, so a simple "statement of compliance" should not guarantee anything...

Celery actually makes this pretty simple, since you're already putting the tasks on a queue. All that changes with more workers is that each worker takes whatever's next on the queue - so multiple workers can process at once, each on their own machine. There's three parts to this, and you've already got one of them. Shared storage, so that all machines can access the same files A broker that can hand out tasks to multiple workers - redis is fine for that Workers on multiple machines Here's how you set it up: User uploads file to front-end server, which stores in your shared storage (e.g. S3, Samba, NFS, whatever), and stores the reference in the database Front-end server kicks off a celery task to process the file e.g. def my_view(request): # ... deal with storing the file file_in_db = store_file(request) my_process_file_task.delay(file_in_db.id) # Use PK of DB record # do rest of view logic... On each processing machine, run celery-worker: python manage.py celery worker --loglevel=INFO -Q default -E Then as you add more machines, you'll have more workers and the work will be split between them. Key things to ensure: You must have shared storage, or this gets much more complicated Every worker machine must have the right Django/Celery settings to be able to find the redis broker and the shared storage (e.g. S3 bucket, keys etc)

Currently we have everything setup on single cloud server, that includes: Database server Apache Celery redis to serve as a broker for celery and for some other tasks etc Now we are thinking to break apart the main components to separate servers e.g. separate database server, separate storage for media files, web servers behind load balancers. The reason is to not to pay for one heavy server and use load balancers to create servers on demand to reduce cost and improve overall speed. I am really confused about celery only, have anyone ever used celery on multiple production servers behind load balancers? Any guidance would be appreciated. Consider one small use case which is currently how it is been done on single server (confusion is that how that can be done when we use multiple servers): User uploads a abc.pptx file->reference is stored in database->stored on server disk A task (convert document to pdf) is created and goes in redis (broker) queue celery which is running on same server picks the task from queue Read the file, convert it to pdf using software called docsplit create a folder on server disk (which will be used as static content later on) puts pdf file and its thumbnail and plain text and the original file Considering the above use case, how can you setup up multiple web servers which can perform the same functionality?
