Instead of adding django package as external library, add the containing folder of django. For example if folder hierarchy is something like /site-package/django than add site-package as external library and not django.

I am creating my first Django project from docs.djangoproject.com. After completing tutorial 4, I tried to import my project in LiClipse. But LiClipse is showing error of Unresolved Import however my projects works perfectly fine. I have added django in external library. Please help me with this issue. LiClipse shows error only with django libraries and not with any other python library

You can probably feed the data. You will need to use MXNet Iterators to get the data out of the records, and then each record you will need to cast to something that Tensorflow understands.

There is no need for sudo if you want to install packages locally. Generally, you should always use a virtualenv; once that is activated, all packages install within that virtualenv only, with no need for admin privileges.

I want to install some python packages on a remote server where I can actually log in and work on some existing python packages. Sometimes I need new python packages like easydict, then I have to install it. However, since I don't have access to the root (I mean I cannot sudo). How to solve this problem? Is it impossible to debug on someone else's computer where you cannot even "sudo"?

I'm usually a huge proponent for DRF. It's simple to implement an easy use case, yet INCREDIBLY powerful for more complex uses. However, if you are not using Django models for all your data, I think JsonResponse might be easier. Running queries and manual manipulation (especially if it is only a single endpoint) might be the way to go. Sorry for not weighing in on the other part of the question.

I’m currently working on improving a Django project that is used internally at my company. The project is growing quickly so I’m trying to make some design choices now before it’s unmanageable to refactor. Right now the project has a two really important models the rest of the data in the database that supports the each application in the project is added into the database through various separate ETL processes. Because of this the majority of data used in the application is queried in each view via SQLAlchemy using a straight up multiline string and passing the data through to the view via the context param when rendering rather than using the Django ORM. Would there be a distinct advantage in building models for all the tables that are populated via ETL processes so I can start using the Django ORM vs using SQLAlchemy and query strings? I think it also makes sense to start building an API rather than passing a gigantic amount of information through to a single view via the context param, but I’m unsure of how to structure the API. I’ve read that some people create an entirely separate app named API and make all the views in it return a JsonResponse. I’ve also read others do this same view based API but they simply include an api.py file in each application in their Django project. Others use the Django REST API Framework, which seems simple but is slightly more complicated than just returning JsonResponse via a view. There is really only one place where a users interaction does anything but GET data from the database and that portion of the project uses Django REST Framework to perform CRUD operations. That being said: Which of these API structures is the most typical, and what do I gain/lose by implementing JsonResponse views as an API vs using the Django REST Framework? Thanks you in advance for any resources or advice anyone has regarding these questions. Please let me know if I can add any additional context.

Would there be a distinct advantage in building models for all the tables that are populated via ETL processes so I can start using the Django ORM vs using SQLAlchemy and query strings? Yes, a centralized, consistent way of accessing the data, and of course, one less dependency on the project. Which of these API structures is the most typical, and what do I gain/lose by implementing JsonResponse views as an API vs using the Django REST Framework? In general terms, JSON is used for data, and REST for APIs. You mentioned that Django-REST is already in use, so if there's any tangible benefit from having a REST API, I'd go with it

I'm currently using django and putting python code in my views.py to run them on my webpages. There is an excerpt of code that requires a certain class from a python file to work sort of like a package but it is just a python file I was given to use in order to execute a certain piece of code. How would I be able to reference the class from my python file in the django views.py file? I have tried putting the python file in my site packages folder in my Anaconda3 folder and have tried just using from [name of python file] import [class name] in the views.py file but it does not seem to recognize that the file exists in the site packages folder. I also tried putting the python file in the django personal folder and using from personal import [name of file] but that doesn't work either

I'm making a web.py app. I'm using a unloadhook function to check if a certain var is in the session for each call. I need to redirect (to index) if it's not there. However, firefox gives me the message that the redirect will never terminate when I call web.seeother in the unloadhook function. I can correctly detect both cases in the unloadhook and treat the case with the var in the session, but not the second. def xCheck(): if 'x' in session: print >> sys.stderr, "x in" print >> sys.stderr, str(dict(session)) return else: print >> sys.stderr, "x out" return web.seeother('/') app.add_processor(web.unloadhook(sessionCheck))

Store one at a time until you absolutely cannot anymore, then design something else around your specific problem. SQL is a declarative language, meaning "give me all records matching X" doesn't tell the db server how to do this. Consequently, you have a lot of ways to help the db server do this quickly even when you have hundreds of millions of records. Additionally RDBMSs are optimized for this problem over a lot of years of experience so to a certain point, you will not beat a system like PostgreSQL. So as they say, premature optimization is the root of all evil. So let's look at two ways PostgreSQL might go through a table to give you the results. The first is a sequential scan, where it iterates over a series of pages, scans each page for the values and returns the records to you. This works better than any other method for very small tables. It is slow on large tables. Complexity is O(n) where n is the size of the table, for any number of records. So a second approach might be an index scan. Here PostgreSQL traverses a series of pages in a b-tree index to find the records. Complexity is O(log(n)) to find each record. Internally PostgreSQL stores the rows in batches with fixed sizes, as pages. It already solves this problem for you. If you try to do the same, then you have batches of records inside batches of records, which is usually a recipe for bad things.

I am writing a Django application that will have entries entered by users of the site. Now suppose that everything goes well, and I get the expected number of visitors (unlikely, but I'm planning for the future). This would result in hundreds of millions of entries in a single PostgreSQL database. As iterating through such a large number of entries and checking their values is not a good idea, I am considering ways of grouping entries together. Is grouping entries in to sets of (let's say) 100 a better idea for storing this many entries? Or is there a better way that I could optimize this?

I was able to write a conversion script, and it's working now, thanks!

So I am currently working on a project that involves the google maps API. In order to display data on this, the file needs to be in a geojson format. So far in order to accomplish this, I have been using two programs, 1 in javascript that converts a .json to a CSV, and another that converts a CSV to a geojson file, which can then be dropped on the map. However, I need to make both processes seamless, therefore I am trying to write a python script that checks the format of the file, and then converts it using the above programs and outputs the file. I tried to use many javascript to python converters to convert the javascript file to a python file, and even though the files were converted, I kept getting multiple errors for the past week that show the converted program not working at all and have not been able to find a way around it. I have only seen articles that discuss how to call a javascript function from within a python script, which I understand, but this program has a lot of functions and therefore I was wondering how to call the entire javascript program from within python and pass it the filename in order to achieve the end result. Any help is greatly appreciated.

Peewee will use either the standard library sqlite3 module or, if you did not compile Python with SQLite, Peewee will look for pysqlite2. The problem is most definitely not with Peewee on this one, as Peewee requires a SQLite driver to use the SqliteDatabase class... If that driver does not exist, then you need to install it.

This is a great question Arnaud, in the past Ive done the following: Create a text project parameter, and populate it with XML (yes you can have line breaks in a text parameter). This is similar to what Ideate BIM Link does (check the project parameters of any project that has used BIM Link). This is a long-winded method for keeping data persistent between commands. The second part (saving a walls IDs) is more difficult I think, as I understand it every time you open a project the IDs are reassigned. You could test this to see if its the case? Another method could involve using an External command that lingers after you have finished selecting walls. Could you go into a little more info about what youre wanting to achieve?

I'm currently using Revit Python Shell 2017 and I'd like let's say to make "communicate" different canned commands. For instance, let's say I load a house model, and I create some additional walls on it, via a canned command that I would have previously created. While creating these walls, I could store all these new walls IDs in a variable, as a list. Now, if I want to delete exactly these walls afterwards, I'd like to identify them using their IDs that I stored in the list, then delete them. If I was in an interactive Python Shell session, well the "IDs list" variable would still be accessible (as long as I don't close the shell), and I could just retrieve the IDs from it, then delete the walls. But what if I'm using canned commands? The first command would be "create the walls", and the 2nd would be "erase these walls". But that "IDs list" variable doesn't exists in the second canned command environment, so that I can't use it to erase the walls. So, what would be the approach? Of course in this example I could identify the walls in the second command using a different methodology, such as asking the user to select them etc etc.. But the idea I'm going for would be the store that list from the first command "somewhere in Revit", and retrieve it when calling the second command. I could write the list to an external text file, and read the file in the second command... but is there a cleaner way? I'm sorry for the beginner's language used here, and hope that my question is clear enough! And that somebody can help ;) Best, Arnaud.

Is it possible to keep a variable active with Revit Python Shell, using canned commands?

After querying using 'condor_q -analyse jobNo.' the error message is "Hold reason: Error from Ubuntu: Failed to execute '/var/lib/condor/execute/dir_12033/condor_exec.exe': (errno=8: 'Exec format error'). I am unsure how to resolve this error, any help would be much appreciated. As I am relatively new to HTCondor and Ubuntu could any guidance be step wise and easy to follow I am running Ubuntu 16.04 and the latest release of HTCondor

socket.SOCK_STREAM should be passed in the type field. Using it in the proto field probably has a very random effect, which is what you're seeing. Proto only takes the IPPROTO constants. For a raw socket, you should use type = socket.SOCK_RAW. I'm not sure getaddrinfo supports that though, it's mostly for TCP and UDP. It's probably better to have some actual code in your questions. It's much easier to see what's going on then.

I'm busy trying to use socket.getaddrinfo() to resolve a domain name. When I pass in: host = 'www.google.com', port = 80, family = socket.AF_INET, type = 0, proto = 0, flags = 0 I get a pair of socket infos like you'd expect, one with SocketKind.SOCK_DGRAM (for UDP) and and the other with SocketKind.SOCK_STREAM (TCP). When I set proto to socket.IPPROTO_TCP I narrow it to only TCP as expected. However, when I use proto = socket.SOCK_STREAM (which shouldn't work) I get back a SocketKind.SOCK_RAW. Also, Python won't let me use proto = socket.IPPROTO_RAW - I get 'Bad hints'. Any thoughts on what's going on here?

It's possible for the value of any cell to be null if the cell has never had any value set (e.g. if you add a value to a cell in a new row, all the other cells will be null). I'm guessing that's what you're seeing. If you check one of those checkbox cells, save, then uncheck it, you should see its value as false in the API. For the purposes of your program logic, you can treat any null checkbox cells as unchecked.

Whenever I retrieve a SmartSheet row and loop through the cells within it, all cells of type CHECKBOX always have a displayValue or value of Null, regardless of the status of the checkbox on the sheet. Has anyone else experienced this? (I am using their python sdk)

If you want to do this with only manipulating your Python program, you would have to run it all day. This would waste CPU resources. It's best to use cron to schedule your unix system to run a command for you every 2 hours. In this case, it'd be your python program.

I'm trying to read from a Google sheet say every 2 hours. I have looked at both the API for Google sheets and also the Google Apps Script. I'm using Python/Flask, and what I'm specifically confused about is how to add the time trigger. I can use the Google Sheets API to read from the actual file,but I'm unsure of how to run this process every x hours. From my understanding, it seems like Google Apps Script, is for adding triggers to doc, sheets, etc, which is not really what I want to do. I'm pretty sure I'm looking in the wrong area for this x hour read. Should I be looking into using the sched module or Advanced Python Scheduler?Any advice on how to proceed would be very appreciated.

Extract the zip file to the site-packages folder. Find the qpyplus folder in that Lib/python3.2/site-packages extract here that's it.Now you can directly use your module from REPL terminal by importing it.

I found this great module on within and downloaded it as a zip file. Once I extracted the zip file, i put the two modules inside the file(setup and the main one) on the module folder including an extra read me file I needed to run. I tried installing the setup file but I couldn't install it because the console couldn't find it. So I did some research and I tried using pip to install it as well, but that didn't work. So I was wondering if any of you could give me the steps to install it manually and with pip (keep in mind that the setup.py file needs to be installed in order for the main module to work). Thanks!

You can pass a string to SAS using the -sysparm command line option, and this string will be available in SAS as the &sysparm automatic variable. E.g. (from the command line:) sas myprogram.sas -sysparm myparam If you need to parse the string inside SAS, the %scan() macro function will probably be useful.

I will admit that I have no experience in this, but maybe a sort of watchdog timer could work? A timer would count up to your desired time, but anytime an element is activated it would reset the counter. This concept is used in micro-controllers a lot but I'm not sure how you would apply it to python.

Short answer is no. Google deepdream is an iPython notebook with dependencies on caffe which itself has several dependencies. There is however no reason why someone couldn't develop a similar tool for Android. There is an app called dreamscope for producing these kinds of images that is available for android, but I would presume they do all of their image computation in the cloud.

I'm a student, I am a beginner with beaglebones. I have a project and in the project we have a BeagleBone Black connected to a battery and solar panels. It will work autonomously, and the beagle will send datas by the 3G network through an 3G usb. What I want to do is to save as more energy as it's possible. What I thought first was to switch on hibernation or sleep mode the beaglebone. To switch on hibernate/sleep mode and then wake up the Beagle every x seconds or minutes or anything else. So I want to know if it's possible and if there is an OS more adapted for that use. I succeeded to disable the usb chipset and then to reactivate it several minutes later. Thank you if you can help me !

I'm in a similar situation. We've done most of our development in Python (primarily Pandas) and now we're moving into Spark as our environment has matured to the point that we can use it. The biggest disadvantage I see to PySpark is when we have to perform operations across an entire DataFrame but PySpark doesn't directly support the library or method. For example, when trying to use the Lifetimes library, this is not supported by PySpark so we either have to convert the PySpark Dataframe to a Pandas Dataframe (which takes a lot of time and loses the advantage of the cluster) or convert the code to something PySpark can consume and parallelize across the PySpark DataFrame.

Recently I've been working a lot with pySpark, so I've been getting used to it's syntax, the different APIs and the HiveContext functions. Many times when I start working on a project I'm not fully aware of what its scope will be, or the size of the input data, so sometimes I end up requiring the full power of distributed computing, while on others I end up with some scripts that will run just fine on my local machine. My question is, is there a disadvantage to coding with pySpark as my main language as compared to regular Python/Pandas, even for just some exploratory analysis? I ask mainly because of the cognitive work of switching between languages, and the hassle of moving my code from Python to pySpark if I do en up requiring to distribute the work. In term of libraries I know Python would have more capabilities, but on my current projects so far don't use any library not covered by Spark, so I'm mostly concerned about speed, memory and any other possible disadvantage; which would perform better on my local machine?

After a couple of days of some tests, I was able to figure out how to work around this problem. Instead of os.system, I am using subprocess.call("script.py arg1 arg2 ..., shell=True) for each script I need to run. Also, I used chmod +x (in linux) before transferring the scripts to windows to ensure they're an executable (someone can hopefully tell me if this was really necessary). Then without having to install python a colleague was able to run the program, after I compiled it as a single file with pyInstaller. I was also able to do the same thing with blast executables (where the user did not have to install blast locally - if the exe also accompanied the distribution of the script). This avoided having to call bipython ncbiblastncommandline and the install.

I'm using tkinter and pyinstaller/py2exe (either one would be fine), to create an executable as a single file from my python script. I can create the executable, and it runs as desired when not using the bundle option with py2exe or -F option with pyinstaller. I'm running third party python scripts within my code with os.system(), and can simply place these scripts in the 'dist' dir after it is created in order for it to work. The command has several parameters: input file, output file, number of threads..etc, so I'm unsure how to add this into my code using import. Unfortunately, this is on Windows, so some colleagues can use the GUI, and would like to have the single executable to distribute. **EDIT:**I can get it to bundle into a single executable, and provide the scripts along with the exe. The issue still however, is with os.system("python script.py -1 inputfile -n numbthreads -o outputfile..") when running the third party scripts within my code. I had a colleague test the executable with the scripts provided with it, however at this point they need to have python installed, which is unacceptable since there will be multiple users.

How about writing scripts outputs to files ,and construct a web interface that consumes this files and displays them in read-only mode? For example in R you can use sink() to route the output messages to a file, you then construct a web interface that simply displays this file.

Reading the file serially is your best option since (hardware wise) it gives you the best read throughout. Usually the slow part is not in the data reading but in its processing...

I have to read a file in chunks of 2KB and do some operation on those chunks. Now where I'm actually stuck is, when the data needs to be thread-safe. From what I've seen in online tutorials and StackOverflow answers, we define a worker thread, and override its run method. The run method uses data from a queue which we pass as an argument, and which contains the actual data. But to load that queue with data, I'll have to go through the file serially, which eliminates parallelism. I want that multiple threads read the file in parallel manner. So I'll have to cover the read part in the run function only. But I'm not sure how to go with that. Help needed.

I am currently working on my thesis, which involves dealing with quite a sizable dataset: ~4mln observations and ~260ths features. It is a dataset of chess games, where most of the features are player dummies (130k for each colour). As for the hardware and the software, I have around 12GB of RAM on this computer. I am doing all my work in Python 3.5 and use mainly pandas and scikit-learn packages. My problem is that obviously I can't load this amount of data to my RAM. What I would love to do is to generate the dummy variables, then slice the database into like a thousand or so chunks, apply the Random Forest and aggregate the results again. However, to do that I would need to be able to first create the dummy variables, which I am not able to do due to memory error, even if I use sparse matrices. Theoretically, I could just slice up the database first, then create the dummy variables. However, the effect of that will be that I will have different features for different slices, so I'm not sure how to aggregate such results. My questions: 1. How would you guys approach this problem? Is there a way to "merge" the results of my estimation despite having different features in different "chunks" of data? 2. Perhaps it is possible to avoid this problem altogether by renting a server. Are there any trial versions of such services? I'm not sure exactly how much CPU/RAM would I need to complete this task. Thanks for your help, any kind of tips will be appreciated :)

You seem to be misunderstanding what the TF-IDF vectorization is doing. For each word (or N-gram), it assigns a weight to the word which is a function of both the frequency of the term (TF) and of its inverse frequency of the other terms in the document (IDF). It makes sense to use it for words (e.g. knowing how often the word "pizza" comes up) or for N-grams (e.g. "Cheese pizza" for a 2-gram) Now, if you do it on lines, what will happen? Unless you happen to have a corpus in which lines are repeated exactly (e.g. "I need help in Python"), your TF-IDF transformation will be garbage, as each sentence will appear exactly once in the document. And if your sentences are indeed always similar to the punctuation mark, then for all intents and purposes they are not sentences in your corpus, but words. This is why there is no option to do TF-IDF with sentences: it makes zero practical or theoretical sense.

I'm trying to analyze a text which is given by lines, and I wish to vectorize the lines using sckit-learn package's TF-IDF-vectorization in python. The problem is that the vectorization can be done either by words or n-grams but I want them to be done for lines, and I already ruled out a work around that just vectorize each line as a single word (since in that way the words and their meaning wont be considered). Looking through the documentation I didnt find how to do that, so is there any such option?

In Java you can match a combination of Thai en English with: ^[\\p{L}\\p{javaUnicodeIdentifierPart}\\p{Blank}\\p{P}]*$ Breakdown: \\p{L} is an 'normal' letter \\p{javaUnicodeIdentifierPart} matches a Thai letter \\p{Blank} matches a space character \\p{P} matches punctuation. I'm not an expert in the Thai language (other than that I recognize it), but without the punctuation-match the string does not match.

I need to vectorize text documents in Thai (e.g Bag of Words, doc2vec). First I want to go over each document, omitting everything except the Thai characters and English words (e.g. no punctuation, no numbers, no other special characters except apostrophe). For English documents, I use this regular expression: [^a-zA-Z' ]|^'|'$|'' For Thai documents, I cannot find the right regular expression to use. I know that the Unicode block for Thai is u0E00–u0E7F. I tried [^ก-๛a-zA-Z' ]|^'|'$|'' and many other combinations but they don't succeed. For example: I want "ทรูวิชั่นส์ ประกาศถ่ายทอดสดศึกฟุตบอล พรีเมียร์ ลีก อังกฤษ ครบทุกนัดเป็นเวลา 3 ปี ตั้งแต่ฤดูกาล 2016/2017 - 2018/2019 พร้อมด้วยอีก 5 ลีกดัง อาทิ ลา ลีกา สเปน, กัลโช เซเรีย เอ อิตาลี และลีกเอิง ฝรั่งเศส ภายใต้แพ็กเกจสุดคุ้ม ทั้งผ่านมือถือ และโทรทัศน์ some, English words here! abc123" to be: "ทรูวิชั่นส์ ประกาศถ่ายทอดสดศึกฟุตบอล พรีเมียร์ ลีก อังกฤษ ครบทุกนัดเป็นเวลา ปี ตั้งแต่ฤดูกาล พร้อมด้วยอีก ลีกดัง อาทิ ลา ลีกา สเปน, กัลโช เซเรีย เอ อิตาลี และลีกเอิง ฝรั่งเศส ภายใต้แพ็กเกจสุดคุ้ม ทั้งผ่านมือถือ และโทรทัศน์ some English words here abc"

Executing the exe from the console works out fine. Thanks.

so I made that python program using several module including os, zipfile, time, datetime, shutil, shelve and ftplib. I froze it with cx_freeze, it won't run on the target machine (but it run on mine). I'm super new to cx_freeze, but I've poked around a bit and I suspect it's a module ot found error. Trouble is, when I execute the exe on the target machine the window doesn't stay open long enough for me to catch the error message so I can't even narrow down the issue to try and solve it. Any idea on how I could deal with it?

cx_freeze freezed python program doesn't run - no time to see the error message on executing

You just have to detect whenever the state of the button is toggled. When toggled if it's pushed down you will need to store the current time with pressedTime = time.time(). When released, to get how long the button have been pushed down, you just do : howLong = time.time() - pressedTime

I'm trying to write a little code that detects how long a button connected to my Raspberry Pi is pushed down, not just if it's pushed. Is there an easy way to do this with Python? Thanks!

This is because the attribute lookup searches all bases of type(a)(type(a).__mro__), rather than all types of type(a)(type(type(a))). Also, type(self) is not called continuously, so the lookup chain looks like this: a.__dict__['x'] type(a).__dict__['x'] b.__dict__[x] for b in type(a).__mro__ raise AttributeError As @jsbueno wisely pointed out in the comment, the second step is actually included in the third one. This is because for any class, let's say class C, C itself is exactly the first item in C.__mro__.

According to Python 2.7.12 documentation, 3.4.2.3. Invoking Descriptors¶: The default behavior for attribute access is to get, set, or delete the attribute from an object’s dictionary. For instance, a.x has a lookup chain starting with a.__dict__['x'], then type(a).__dict__['x'], and continuing through the base classes of type(a) excluding metaclasses. But why metaclasses are excluded? If you continuously call type(self), no matter what self is, an instance object or a type object, you'll eventually get <type 'type'>. So I can't understand why metaclasses enjoy this "privilege". By the way, I'm a little confused by this quotation: For instance objects, object.__getattribute__ are used, so I think the lookup chain should look like this: a.__dict__['x'] type(a).__dict__['x'] b.__dict__[x] for b in type(a).__mro__ type(b).__dict__[x] for b in type(a).__mro__ c.__dict__[x] for c in type(b).__mro__ ...... Am I right?

Why aren't metaclass's attributes searched in instance attribute lookups?

As for the how/why, sys is only imported once (when python starts up). When sys is imported, it's argv member gets populated with the commandline arguements. Subsequent import statements return the same sys module object so no matter where you import sys from, you'll always get the same object and therefore sys.argv will always be the same list no matter where you reference it in your application. Whether you should be doing commandline parsing in more than one place is a different question. Generally, my answer would be "NO" unless you are only hacking together a script to work for the next 2 or 3 days. Anything that you expect to last should do all it's parsing up front (probably with a robust argument parser like argparse) and pass the data necessary for the various functions/classes to them from it's entry point.

I recently discovered (Much to my surprised) you can call command line args in files other than the one that is explicitly called when you enter it. So, you can run python file1.py abc in command line, and use sys.argv[1] to get the string 'abc' from within file2.py or file3.py. I still feel like this shouldn't work, but I'm glad it does, since it saved me a lot of trouble. But now I'd really appreciate an answer as to why/how this works. I had assumed that sys.argv[1] would be local to each file.

Django channels gives to Django the ability to handle more than just plain HTTP requests, including Websockets and HTTP2. Think of this as 2 way duplex communication that happens asynchronously No browser refreshing. Multiple clients can send and receive data via websocket and django channels orchestrates this intercommunication example a group chat with simultaneously clients accessing at the same time. You can achieve background processing of long running code simliar to that of a celery to a certain extent, but the application of channels is different to that of celery. Celery is an asynchronous task queue/job queue based on distributed message passing. As well as scheduling. In layman's terms, I want to fire and run a task in the background or I want to have a periodical task that fires and runs in the back on a set interval. You can also fire task in a synchronous way as well fire and wait until complete and continue. So the key difference is in the use case they serve and objectives of the frameworks

Other answers, greatly explained the diff, but in facts Channels & Celery can both do asynchronous pooled tasks in common. Channels and Celery both use a backend for messages and worker daemon(s). So the same kind of thing could be implemented with both. But keep in mind that Celery is primary made for and can handle most issue of task pooling (retries, result backend, etc), where Channels is absolutely not made for.

The maven path for all the artifacts is not the same that gets generated when you run it or export the project. You can check this by exporting the project as Jar/War/Ear file and viewing it via winRAR or any other tool. The resources should be in jar parallel to com directory if its a jar project, but you can double check it.

I am building my Java project with Maven and I have a script file that ends up in the target/classes/resources folder. While I can access the file itself via this.getClass.getResource("/lookUpScript.py").getPath(), I cannot execute a shell command with "." + this.getClass.getResource("/lookUpScript.py").getPath(); this ultimately ends up being ./lookUpScript.py. To execute the shell command I am using a method that is part of my company's code that I can get to work fine with any command not involving a file. Is there a standard way of accessing files located in the resources area of a Maven build that may fix this?

Well, that's a simplification. The float type in Python is double-precision. The int type has integer precision, but only limited by memory. Large numbers can have far more significant digits than a double float. When using NumPy, you may choose the precision you want.

The same thing is happening with my shell. In the older versions, this does not happen. I've also noticed that when I press Python 3.5.2 Module Docs, I have my Internet browser open up and I see my directory being displayed onscreen. It looks like: C:\Users\mycomputername\AppData\Local\Programs\Python\Python35-32\DLLs. Is that suppose to happen? Is that secured? I don't know. I've also found that this prints out whenever I "imported" something. So if I use an import command, and put it right before the line of my random name, it will print out that "RESTART" thing. It's always at the beginning. Or what it reads as the beginning.

CIsForCookies, my guess is that you don't actually have a complete script; maybe you have just a function definition and you haven't included a line to run that function. (I had this problem and then remembered to call the function I defined; the problem went away.)

I have been looking for a feature where PyCharm notifies me that a script has finished running in the console after each run. At present, I have to add print('done') after each code. I got smarter so I defined d = 'done' once and after each run I simply add a d so it prints out 'done' which I thought to be more of a time saver. Now I am even more lazy and whenever I press F10 (my run command button), I want PyCharm to automatically run a small script with d = 'done' in it right after finishing running the main script. Is there a way to do this?

You can take a couple of approaches. If there are lots of possibilities, as you say, you can treat this as a machine learning problem and use approach 1. Otherwise 1, if the possibilities are limited (say, around 5), you can use the second approach. Approach 1: Consider it a machine learning problem. Classify each sentence in the text as 0 or 1 depending on if it contains the year of experience. This can be done by training some data manually. Against each training example, you will assign a label. For example: Job Experience: 3 years (Label 1) Studying for two years (Label 0) Working hard for years (Label 0) Two years of experience (Label 1) Experience: 2010-2014 (Label 1) Once you have a lot of examples, you can use skicit-learn or a similar package to train a model. Approach 2: 1- Search for years. Either, it could be the exact word (year or years), or a four digit number (e.g, 2014). 2- If 1 passes, search for the word experience (or something like that) in a close proximity. If both 1 and 2 pass, then you have years of experience. Then, depending on what you want, you can further extract.

In Python I have learnt that creating ints like 0b01101101 will create a binary literal. Say I have a string data type of "01101101" is there a way to convert this to a binary literal? The example usage is that I am going to create a data packet slowly building up the byte with relivant pices of data (Setting bits according to variables). Once I have the string, I'll need to write raw binary over a serial connection. Is it possible to convert the string "01101101" to 0b01101101 so it is a binary literal. Another exammple of my target for this, if it helps. is so I can dynamically create the binary data on the fly without having do do massive bitwise operations, I see it simpler just to make up a string of 1's and 0's as I collate data then convert it to a binary literal. Of course if there is a better way to go about it, improvements would be gladly accepted.

Is there a way of converting a string of 1's and 0's to its binary counterpart, i.e. not ASCII

When I want to save a Jupyter Notebook I right click the mouse, select print, then change Destination to Save as PDF. This does not save the analysis outputs though. So if I want to save a regression output, for example, I highlight the output in Jupyter Notebook, right click, print, Save as PDF. This process creates fairly nice looking documents with code, interpretation and graphics all-in-one. There are programs that allow you to save more directly but I haven't been able to get them to work.

The new release of IPython does not depend any more on readline but uses the pure Python library prompt-toolkit, solving maintenance problems on Apple's and Windows' systems. A new feature is the ability to edit a multi-line code block, using the cursor keys to move freely in the code block — with this power it comes, at least for me, a problem: because a ret inserts a new line in your code, to pass the whole block to the interpreter you have to use the shortcut alt+ret or possibly the less convenient key sequence esc followed by ret. I say, this is a problem, because my terminal emulator of choice is the XTerm and, on many Linux distributions, the shortcut alt+ret is not passed to the application but it is directly used by the XTerm in which IPython is running, to toggle the screen-fullness of the said terminal (@ThomasDickey, xterm's mantainer and co-author pointed out that, by default, xterm doesn't care to send to the application the modifier bit on Enter even when one unbinds the Fullscreen action). For this reason I'd like to modify at least this specific IPython key binding. I've found instructions (sort of) for the previouos versions, the readline based ones, of IPython that do not apply to the new, 5.0 version. What I would need are instructions that lead me to find, in IPython's user documentation, the names of the possible actions that I can bind, the names of the shortcuts to bind with the actions and the procedure to follow to configure a new key binding. Failing to have this type of canonical answer, I may be happy with a recipe to accomplish this specific keybinding, with the condition that the recipe still works in IPython 6.0

Use a layered approach: downloading, parsing, storage, analysis. Separate the layers. Most importantly, don't just download data and then store it in the final parsed format. You will inevitably realise you missed something and need to scrape it all over again. Use something like requests + requests_cache (I found that extending requests_cache.backends.BaseCache and storing it on the filesystem is more convenient examining scraped html than the default sqlite storage backend). For parsing you're already using beautiful soup which works fine. For storage & analysis use a database. Avoid the temptation to go with NoSQL -- as soon as you need to run aggregate queries you'll regret it.

I am scraping data of football player statistics from the web using python and Beautiful Soup. I will be scraping from multiple sources, and each source will have a variety of variables about each player which include strings, integers, and booleans. For example player name, position drafted, pro bowl pick (y/n). Eventually I would like to put this data into a data mining tool or an analysis tool in order to find trends. This will need to be searchable and I will need to be able to add data to a player's info when I am scraping from a new source in a different order. What techniques should I use to store the data so that I will best be able to add too it and the analyze it later?

I would like to use Jupyter/IPython notebooks for writing reports, but I would prefer to avoid the browser interface. Instead, I would like to be able to write the notebook in some text-based format, e.g. markdown, and export the notebook afterwards. Essentially I would like to use Jupyter in a Knitr-esque workflow. Is this currently possible? Thanks in advance.

Multithreading is not related to billing in any way - you still pay for one instance even if 10 threads are running in parallel on that instance.

I have an appserver that is getting painfully complicated in that it has to buffer data from incoming requests then push those buffers out, via pubsub, after enough has been received. The buffering isn't the problem, but efficient locking is... hairy, and I'm concerned that it's slowing down my service. I'm considering dropping thread safety in order to remove all the locking, but I'm worried that my app instance count will have to double (or more) to handle the same user load. My understanding is that a threadsafe app is one where each thread is a billed app instance. In other words, I get billed for two instances by allowing multiple threads to run in a process, with the only advantage being that the threads can share memory and therefore, have a smaller overall footprint. So to rephrase, does a multithreaded app instance handle multiple simultaneous connections, or is each billed app instance a separate thread - only capable of handling one request at a time? If I remove thread safety, am I going to need to run a larger pool of app instances?

What's the advantage of making your appengine app thread safe?

Refactor your code such that what you are drawing in your EVT_PAINT handler can be called passing it the wx.DC to be drawn upon, and then call that from your paint handler with the wx.PaintDC or whatever you are currently using. When you want to save it to an image call the same code passing a wx.MemoryDC with a wx.Bitmap selected into it. When it's done the bitmap will have the same contents as the window, and you can then save it to a file or whatever you need to do with it.

Resources are just a resource-based abstraction over the clients. They can't do anything the clients can't do, but in many cases they are nicer to use. They actually have an embedded client that they use to make requests. The downside is that they don't always support 100% of the features of a service.

Boto3 Mavens, What is the functional difference, if any, between Clients and Resources? Are they functionally equivalent? Under what conditions would you elect to invoke a Boto3 Resource vs. a Client (and vice-versa)? Although I've endeavored to answer this question by RTM...regrets, understanding the functional difference between the two eludes me. Your thoughts? Many, many thanks! Plane Wryter

Personally I do. Virtualenvs help you keep the dependencies required for a project organised and manageable. If you have a django 1.7 project, it will require django1.7 and thus install it in your virtualenv. Without a virtualenv, you might decide to take on a project that requires django1.10. This means your django1.7 project might break. To avoid such a scenario use a virtual environment.

Do you create a new virtualenv every time you start a new project? I'm going through some tutorials on the web and they create a virtualenv first then pip install django in the virtualenv. But there's one tutorial that i saw saying that you wouldn't create a project within the virtualenv and its only used for dependencies.

I just started trying out PyCharm, and while it is very nice, I found the interactive console in debugger (that can be activated with "Show Python Prompt" on a breakpoint) is unusably slow. If I keep pressing enter, for example, after 2-3 tries, I have to wait several seconds for the next prompt to show up. Is this a common experience? I'm running Pycharm with a pretty fast machine (with i7-3770 CPU) so I was wondering if something is wrong.

I solved my issue. The solution was Making my object really simple. In my case, I converted my object to array of simple stringified dictionaries. I used file.write(stringified_dictionaries) directly instead of using pickle. This reduced time for serializing python object to string. Since disk I/O does not require GIL in python, the only moment main thread blocked was the moment of converting my object, which was really short.

Currently I'm using python 3.4.3 and developing PyQt5 application. In my app, there's a QThread, and some large object(100MB) is being (pickle) dumped by the thread. However, dumping that object requires 1~2 seconds, and it blocks the main thread about 1~2 seconds because of GIL. How can I solve this issue(non-blocking the main thread)? I think that serializing my object to string takes time and it requires GIL, eventually blocks the main thread.(As I know, writing to file does not require GIL) I'm thinking about using Cython, but since I'm the beginner in cython, I'm not sure whether or not using Cython will solve this issue. Is there any way to work around this issue? Edit: I tried multiprocessing module, but the intercommunication time (passing shared memory variables across processes) also takes about 1~2 seconds, which eventually gives no advantages.

For a small scale like that, the map projection does not really matter. You can first make the latitude and longitude relative to the map by subtracting from them the latitude and longitude of the top-left-hand corner pixel of the image. To convert the resulting angles to distances, convert them to radians and then multiply them by the average radius of the Earth (about 6371000 m), or if you want to be more precise, multiply them by the radius of the Earth in the area (ranging from 6356752 m at the poles to 6378137 m at the Equator). To convert these distance offsets to points on the map image in pixel coordinates, simply divide them by 250.

When you have a representation of your Python source code as tree (parse tree or abstract syntax tree) you can convert this to a Rascal data type and use Rascal for further processing. This can be achieved by using and connecting an existing Python parser to generate the Rascal representation of your Python program. This could be done by simply dumping the parse tree in a format that can be read by Rascal. Why this complex solution: because the built-in parser generator of Rascal is not (yet) well equipped to parse indentation-sensitive languages like Python.

I can't advise how but I do know (one) why. Direct writing to registers allows one to set up a particular microcontroller. For example, configuring ports or peripherals. This is normally done in C (closer to hardware) but it would be a nice feature if you wanted to use Python for other reasons.

No magic solution here. You have to manage states on your model, specially when working with celery tasks. You might need another field called state with the states: NONE (no action is beeing done), PROCESSING (task was sent to celery to process) and DONE (image was rotated) NONE is the default state. you should set the POCESSING state before calling the celery task (and not inside the celery task, already had bugs because of that) and finally the celery task should set the status to DONE when finished. When the task is fast the user will not see any difference but when it takes some time you might want to add a message "image is being processed, please try again" or something like that At least that's how I do it... Hope this helps

So I've a Django model which has a FileField. This FileField, contains generally an image. After I receipt the picture from a request, I need to run some picture analysis processes. The problem is that sometimes, I need to rotate the picture before running the analysis (which runs in celery, loading the model again getting the instance by the id). So I get the picture, rotate it and save it with: storage.save(image_name, new_image_file), where storage is the django default storage (using AWS S3) The problem is that in some minor cases (lets say 1 in 1000), the picture is not already rotated when running the analysis process in celery, after the rotation process was executed, but after that, if I open the image, is already rotated, so it seems that the save method is taking some time to update the file in the storage, (asynchronously)... Have anyone had a similar issue? Is there a way to check if the file was already updated, like with a callback or a kind of handler? Many thanks!

You can add a script in the Google spreadsheet with an onsubmit trigger. Then you can do whatever you want with the submitted data.

I am creating a web project where I take in Form data and write to a SQL database. The forms will be a questionnaire with logic branching. Due to the nature of the form, and the fact that this is an MVP project, I've opted to use an existing form service (e.g Google Forms/Typeform). I was wondering if it's feasible to have form data submitted to multiple different tables (e.g CustomerInfo, FormDataA, FormDataB, etc.). While this might be possible with a custom form application, I do not think it's possible with Google Forms and/or Typeform. Does anyone have any suggestions on how to parse user submitted Form data into multiple tables when using Google Forms or Typeform?

Using Google Forms to write to multiple tables?

Maybe you can try the following. Find where both pip-s reside (whereis pip, I have it on ~/anaconda2/bin), then cd to the pip directory of the python version you want, and execute it from there.

Using pip with different Python version is a common problem, as I see when I search the Internet. There are a lot of answers around, also in this forum. However nobody seems to encounter the same problem that I have: I use Canopy python most and it was installed first. Later I installed Anaconda. Now when I try to install a program with pip it always install it in Canopy (or refuse to install it because it is already installed in Canopy. for example: $ pip install ipython gives: Requirement already satisfied... but there are no ipython in my Anaconda-folder, it is in the /Enthought/Canopy_64bit/... folder How can I overcome this problem? Both versions are 2.7 and even if one is 2.7.11 and the other 2.7.12, it did not work to distinguish between the two by this.

New point of view: pip dealing with multiple Python versions, Canopy, Anaconda on Linux

If you don't have vertex or edge attributes, your best bet is a simple edge list, i.e. Graph.Read_Edgelist(). The disadvantage is that it assumes that vertex IDs are in the range [0; |V|-1], so you'll need to have an additional file next to it where line i contains the name of the vertex with ID=i.

I have a very large network structure which I am working with in igraph. There are many different file formats which igraph Graph objects can write to and then be loaded from. I ran into memory problems when using g.write_picklez, and Graph.Read_Lgl() takes about 5 minutes to finish. I was wondering if anyone had already profiled the numerous file format choices for write and load speed as well as memory footprint. FYI this network has ~5.7m nodes and ~130m edges.
