This revealed that the label ID for my label was something else ("Label_1" -- the name was "handler_gmail"). So I will make a support method that gets me a label ID by name, and add the label to the message (via modify) using the ID.
Thanks! | 1 | 9 | 0 | I created a label, "handler_gmail", in Gmail's web interface via the typical approach.
When I try to set that label for a message via the Gmail API (Python client library), I get the response HttpError 400, returned "Invalid label: handler_gmail".
I am sure the label exists (I've checked multiple times – no typos).
I am trying to set it like so:
gs.users().messages().modify(userId=username, id=m['id'], body={"addLabelIds": ['handler_gmail']}).execute()
I tried adding a "removeLabelIds": [] key/value pair to the dictionary (thinking maybe it was required), but got the same "Invalid label" error.

Part of the problem was that I was trying to find a solution for moving a sqlite3 database to a server, but it turns out that sqlite3 is only intended for use in simpler local situations. So I decided to migrate to MySQL. The following are the major steps:
I took an old computer that has XP and installed Lubuntu 14.04 as the default OS.
Installed MySQL on Lubuntu: sudo apt-get install mysql-server.
Edit the etc/mysql/my.cnf document's bind-address to match the computers network address.
On the client computer with Python 2.7 installed PyMySQL: easy_install PyMySQL
Works great. Now I'm in the process of making sure the program watches for changes to the database and updates the GUI accordingly. | 1 | 0 | 0 | I wrote a database program using SQLAlchemy. So far, I've been using FreeFileSync to sync the database file over the network for two computers when necessary. I want to learn how to set things up so that the file stays in one place and allows multiple user access but I don't know where to begin.
Is it possible to open and read/write to a SQLAlchemy database on another computer over a network? I couldn't find information on this (or maybe I just don't understand the terminology)?
Are there any courses or topics I should look into that I will be able to apply with Python and SQLAlchemy?
Or would making a web-based program be the best solution? I'm good at algorithms and scientific programming but I'm still a novice at network and web programming. I appreciate any tips on where to start. | SQLAlchemy, how to transition from single-user to multi-user | 1.2 | 1 | 0 | 321 |

The plan is to run this command hourly with cron, and also have it run on user command from a view (i.e. when they add a new item that needs data, I don't want them to wait for the next hour to roll around to see results). The question is:
How can I set up this command such that if it is already currently running, it won't execute? Is there some place where I can stash a variable that can be checked by the script before execution? My current best idea is to have the command monitor stdout for a while to make sure nothing else is executing, but that seems like a hack at best.

My advice, but just to make it simpler, is to define the database schema through migrations in your rails app and build it like the python script doesn't exist.
Once you have completed it, simply start the python script so it can start populating the Database (could be necessary to rename some table in the python script, but no more than this).
If you want to test in your local machine you can one of this:
run the python script in your local machine
configure the database.ymlin your rails app to point to the remote DB (can be difficult if you don't have administration access to the host server, because of port farwarding etc)
The only thing you should keep in mind is about concurrent accesses.
Because you have 2 application that both read and write in your DB, would be better if the python script makes its job in a single and atomic transaction, to avoid your rails app finding the DB in an half-updated state.
You can see the database like a shared box, it doesn't matter how many applications use it. | 1 | 0 | 0 | I have built an application in python that is hosted on heroku which basically uses a script written in Python to store some results into a database (it runs as a scheduled task on daily basis). I would have done this with ruby/rails to avoid this confusion, but the application partner did not support Ruby.
I would like to know if it will be possible to build the front-end with Ruby on Rails and use the same database.
My rails application will need to make use MVC and have its own tables on the database, but it will also use the database that python sends data to just to retrieve some data from there.
Can I create the Rails app and reference the details of the database that my python application uses?

NOTE: I'm a beginner in Python, and I'm using v2.7.8.

b = 0

I know that I can just open Anaconda's version of Python in the command prompt and manually import it, but I'd like to set things us so that I can just double-click on a .py file and Anaconda's version of Python is automatically used. | How can I execute Python scripts using Anaconda's version of Python? | 0 | 0 | 0 | 158,665 |

On click of a button on my website, running on server1, I make a request to run a python script. The python script uses paramiko to make SSH connections to server2, runs the necessary command and writes a response to a plain/text file. This plain/text file is rendered back to the request through django form as a response.
This looks a little dirty now and there are more things to look into like, what happens if the command took very long time to execute or it erred out for some reason.

numpy has lots of useful function handles, such as numpy.fft for Fourier Tranformation, or numpy.conv to do the convolution. This could be critical for image processing.

Microsoft always said that on its system the file extension determined the type of file and its usage. There are already many cross platfomr programs, for example firefox in named firefox on Unix-like systems and firefox.exe on Windows system.
EDIT
That being said, Windows accepts what you give it as command, provided it is in a correct executable format. So if you create a program HelloWorld.exe and rename it HelloWorld.joe :
cmd.exe will start the program when you type HelloWorld.joe at the prompt (tested on Windows XP and Windows 7)
Python 2.7 and 3.4 should start it either using os.system or with the subprocess module (confirmed by eryksun)
You cannot use os.system call with a badly named file (in Microsoft's sense) because under the hood, os.system uses cmd.exe. It is a Microsoft program that looks at the file extension to know what to do with it, and will never execute (as an exe) a file that do not have the exe extension.
You will not be able to use the subprocess module with shell=True for exactly the same reason.

Looking around, os.system is often used to execute .exe files, but I haven't been able to get it working without the .exe extension.

My directory structure looks something like this:

several .py files
logging
com1several .py filescom2several .py files

When using setuptools find_package() function, it finds the "project" package, but it doesn't install any of the folders (implicit sub-packages) inside of "project". When I unzip the .egg file, all I see is the __init__.py file inside, none of the subdirectories or files.
I could just put an __init__.py in every directory, but since those files would all be empty and I don't like the way it makes the structure work, I'm trying to avoid that.
If I move to just outside of my "project" directory, and run the following, it works
python -m project.logging.com1.myfile
but anywhere else it doesn't work, because setuptools isn't installing the sub-directories (implicit namespaces) that don't have __init__.py in them.

I may have to issue corrections on the data, so I am considering versioning the whole directory= 1 toplevel contains 10 level1 dirs, each contain 10 level2 dirs, each containing 200 csv files.
The data is written to files by python processes( pandas frames ).
The question is about performance of writes where the deltas are small like this compared to the entire data.
svn and git come to mind, and they would have python modules to use them.
What works best?

If MIB is available, Manager would be able to perform any SNMP operation knowing either symbolic name or OID of the Agent's variable it is interested in. All required details would be gathered from the MIB.
If MIB is not available, Manager would still have to figure out more or less of the additional details (some are listed above) so those can be hardcoded to the Manager.
For example, a GET operation could be performed having just an OID, however without MIB Manager may have troubles making response value looking human friendly.
Another example is a SET operation that requires Manager to properly encode value -- its type can be dynamically looked up at the MIB or hardcoded into the Manager for specific OIDs.
More complex scenarios involve dynamically building OIDs (for addressing SNMP table entries) using indices structure formally defined by the MIB.
The purpose of the GETNEXT/GETBULK queries is to let Manager be unaware of the exact set of OIDs provided by the Agent. So Manager could iterate over Agent's variables starting from a well known OID (or even its prefix). One of the uses of this feature is SNMP table retrieval.
MIBs are written in a subset of ASN.1 language. Unlike ASN.1, MIBs are very specific to SNMP domain.
To use MIBs with pysnmp you need to pass ASN.1 MIBs to the build-pysnmp-mib shell script (from pysnmp distribution) which would invoke smidump and other tools to convert ASN.1 MIBs into a collection of Python classes representing pysnmp-backed MIB objects. | 1 | 0 | 0 | I am fairly new to the SNMP protocol and have only been introduced to it recently in my computer networking course.
I understand how the manager sends Gets, Sets, GetNext, GetBulk and all that, it will catch Traps and such. One thing I don't entirely understand is the MIB
From what I gather, the MIB is chillen on an agent and the Manager will query for the MIB tree. That is fine, although the Manager needs the OID to be able to properly query. One question I have regards if these are hardcoded or not. Are the OIDs hardcoded in the manager or not?
Other than that, I'm not sure how to build the MIB file, apparently there is some special file type that defines the MIB structure and I don't really get how to use pySNMP to build that. I feel like I would run that on the agent side of things upon startup

The ipcs command can be used to get the information about all ipc objects. It shall provide information about currently active message queues, shared memory segments and semaphores. This is available as part of util-linux.
Another option is to look for shm folder in /proc/ to view the list of currently active shared memory that are in use before and after running your program.
FIFO are special files that are created using mkfifo which you can determine from file type p in ls-l output. Also, you can use the -p option to test whether a file is a pipe.
/proc/<pid>/fd can help to gather more info. The lsof is a very handy tool that can give you the list of open files and the processes that opened them. It can list the PID, PGID, PPID, owner of process, the command that is being executed by the process and the files that are in use by the process.
fuser can provide your the list of PIDs that use the specific files or file systems.
top/htop gives you the list of processes that run in your system. This can give wide range of information ranging from priority of the processes in the form of NI to memory usage via REM or MEM.
iotop can provide a table of current I/O usage by processes or threads on the system by monitoring the I/O usage information output by the kernel.
mpstat can give 'the percentage of time that the CPU or CPUs were idle during which the system had an outstanding disk I/O request' via 'iowait' argument.

Typical hash functions are designed to minimize collision mapping near duplicates to very different hash keys. In cryptographic hash functions, if the data is changed with one bit, the hash key will be changed to a completely different one.
The goal of similarity hashing is to create a similarity hash function. Hash based techniques for near duplicate detection are designed for the opposite intent of cryptographic hash algorithms. Very similar documents map to very similar hash keys, or even to the same key. The difference between bitwise hamming distance of keys is a measure of similarity.
After calculating the hash keys, keys can be sorted to increase the speed of near duplicate detection from O(n2) to O(nlog(n)). A threshold can be defined and tuned by analysing accuracy of training data.
Simhash, Minhash and Local sensitive hashing are three implementations of hash based methods. You can google and get more information about these. There are a lot of research papers related to this topic... | 1 | 3 | 1 | I have 80,000 documents that are about a very vast number of topics. What I want to do is for every article, provide links to recommend other articles (something like top 5 related articles) that are similar to the one that a user is currently reading. If I don't have to, I'm not really interested in classifying the documents, just similarity or relatedness, and ideally I would like to output a 80,000 x 80,000 matrix of all the documents with the corresponding distance (or perhaps correlation? similarity?) to other documents in the set.
I'm currently using NLTK to process the contents of the document and get ngrams, but from there I'm not sure what approach I should take to calculate the similarity between documents.
I read about using tf-idf and cosine similarity, however because of the vast number of topics I'm expecting a very high number of unique tokens, so multiplying two very long vectors might be a bad way to go about it. Also 80,000 documents might call for a lot of multiplication between vectors. (Admittedly, it would only have to be done once though, so it's still an option).
Is there a better way to get the distance between documents without creating a huge vector of ngrams? Spearman Correlation? or would a more low-tech approach like taking the top ngrams and finding other documents with the same ngrams in the top k-ngrams be more appropriate? I just feel like surely I must be going about the problem in the most brute force way possible if I need to multiply possibly 10,000 element vectors together 320 million times (sum of the arithmetic series 79,999 + 79,998... to 1).

I've been trying to use Hough Line Transform where I was supposed to use Hough Probabilistic Transform. The moment I got it, I grouped lines drawn along similar functions, sorted them by length, and used arcsine as well as locations of their ends to find precise degrees at wchich hands stood. | 1 | 4 | 1 | I've been trying to write a program that locates clock's face on picture and then proceeds to read time from it. Locating works fairly well, reading time - not so much.
The cv2.HoughLines function returns angles at which lines lay (measuring from the top of the image) and their distance from upper-left corner of the image. After a bit of tweaking I've managed to convince my code to find a single line for each of clock's hands, but as for now I remain unable to actually read time from it.
Using appropriate formulas I could find intersection of those lines (middle of the clock) and then iterate along the hands in both directions at once. This could tell me the length of each hand (allowing me to tell them apart) as well as at which direction are they pointing. I'm fairly hesitant about implementing this solution though - not only does it seem somehow ugly but also creates certain risks. For example: problems with rounding could cause the program to check the wrong pixel and find the end of line prematurely.

Secondly, before doing any changes to your code I would ask myself the following questions:
What are the improvements/new requirements I want to implement that I can't easily do with the current structure?
Do I have a test suite of the current solution, so that I can regression-test any refactoring? When re-implementing something it is easy to overlook some specific behaviors which are not very well documented but that you/users rely on.
Do those improvements warrant an SQL database? For instance:
Do you need to often run reports out of an SQL database without walking the directory structure?
Is there a problem with walking the directories?
Do you have network or performance issues?
Are you facing an increase in usage?
When implementing an SQL solution, you will need a new task to update the SQL data. If I understand correctly, the reports are currently generated on-the-fly, and therefore are always up-to-date. That won't be the case with SQL reports, so you need to make sure they are up-to-date too. How frequently will you update the SQL database:
a) In real-time? That will necessitate a background service. That could be a operational hassle.
b) On-demand? Then what would be the difference with the current solution?
c) At scheduled times? Then your data may be not up-to-date between the updates.
I don't have any packages or technical approaches to recommend to you, I just thought I'd give you those general software management advices.
In any case, I also have extensive C++ and Python and SQL experience, and I would just stick to Python on this one.
On the SQL side, why stick to traditional SQL engines? Why not MongoDB for instance, which would be well suited to storing structured data such as file information. | 1 | 0 | 0 | I'm looking for open-ended advice on the best approach to re-write a simple document control app I developed, which is really just a custom file log generator that looks for and logs files that have a certain naming format and file location. E.g., we name all our Change Orders with the format "CO#3 brief description.docx". When they're issued, they get moved to an "issued" folder under another folder that has the project name. So, by logging the file and querying it's path, we can tell which project it's associated with and whether it's been issued.
I wrote it with Python 3.3. Works well, but the code's tough to support because I'm building the reports while walking the file structure, which can get pretty messy. I'm thinking it would be better to build a DB of most/all of the files first and then query the DB with SQL to build the reports.
Sorry for the open-ended question, but I'm hoping not to reinvent the wheel. Anyone have any advice as to going down this road? E.g., existing apps I should look at or bundles that might help?

I've narrowed this down to:
When I run "python" in a terminal in my /Home/UsrName/ directory it is version 2.7.5
However when I run "python" in a terminal in /Home/UserName/Downloads/Ipython directory I get 2.6.6
I went into the Ipython folder to run the Ipython Setup file. I think I need to add python27 to a system path so that when I am inside the /Home/UserName/Downloads/Ipython directory and run the install file Ipython knows I am using a required version of python.

timeout: timed out
After importing my modules, the result of socket.getdefaulttimeout() is None (note that this isn't the same situation as what produced the above, since getting those requires an 8-hour stress run on the system).
My code is not setting any timeout values (default or otherwise) AFAICT. I have not yet been able to find any hint that 3rd party libraries are doing so either.
Obviously there's some timeout somewhere in the system. I want to know the numeric value, so that I can have the system back off as it is approached.
This is python 2.7 under ubuntu 12.04.
Edit:
The connection is to localhost (talking to CouchDB listening on 127.0.0.1), so NAT shouldn't be an issue. The timeout only occurs when the DB is under heavy load, which implies to me that it's only when the DB is getting backed up and cannot respond quickly enough to requests, which is why I would like to know what the timeout is, so I can track response times and throttle incoming requests when the response time gets over something like 50% of the timeout. | Python socket.getdefaulttimeout() is None, but getting "timeout: timed out" | 0 | 0 | 0 | 536 |

I developed a widget and I have a button who opens a new window for some settings. The program works fine, but, at a some point, totally randomly, pythonw.exe stops working. It's only when I use the window for settings. The problem happens totally randomly, but more often when I open the window. I tried to make my window with OWW.OWBaseWidget, OWW.OWWidget and OWW.QDialog. I tried too with pythonw.exe and python.exe. I did the same thing that Set Colors of the widget Data Table in Data. But this one crashed too after a moment.
So where is the problem? Orange? Python? Anything else? I have no error message.

If the application uses *.glade or *.ui files you can - depending on how well it is designed re-arrange certain elements and swap out container types.
If there are no such files, you are out of luck. Then the ui is "hard"-coded (as hard as python code can get..) and you have to modify the widget hirarchy by modifying python code yourself.
There is no such editor being able to extract a layout/ui file from code itself.
gtkinspector or formerly known as gtkparasite can modify properties of widgets on the fly but nothing that really modifies the python code of the running application. They sneak around the application code and modify the widget tree from back behind through means of the gtk module lib interface (correct me if I am wrong here, not totally sure). | 2 | 0 | 0 | I want to change the interface of a written application. this application is written in python and GTK .

Glade had code generation features removed years ago, because that leads to unmaintainable code when it's patched by hand after generation, to add the program's internal logic. So either you:
use Glade to generate a ui file, and have to change the python code anyway to use it
or you'll have manually write some code to change the user interface
In either way, you'll have some code to write. If you have lots of changes in the user interface, then convert your program to use Glade ui files. It will take some time, but changes will be easier afterwards. If you only have a couple of changes to do, just do them in the code, it will be faster to do. | 2 | 0 | 0 | I want to change the interface of a written application. this application is written in python and GTK .

viewsets.py | 1 | 0 | 0 | Hi there so my question is probably about best practices when organizing ViewSets and the corresponding Routers in Django Rest Framework.
According to the official documentation, the routers should be stored in the urls.py and the viewsets should be stored in views.py.
My idea of an approach would be having the viewsets in a separate file like for example viewsets.py so that we don't end up mixing the normal Django views and the DRF Viewsets in the same file, improving readability.
The same would go for the routers where we would creaate a file called routers inside each app and register then with the main Default router instance.
These are my thoughts, but i am not sure how to:
1º Do this the proper way (the registering of the viewsets routers and all, should i place DefaultROuter in the __init__.py ?)
2º Is there a better approach?
