I am looking to ingest and write Avro files in GCS with the Python SDK. Is this currently possible with Avro leveraging the Python SDK? If so how would I do this? I see TODO comments in the source regarding this so I am not too optimistic.

How to plot data while it's being processed

You can plot the data as it is being processed, but there's a couple of issues that come along with it in terms of efficiency. Gnuplot needs to do work each time to process your data Gnuplot needs to wait for your operating system to paint your screen whenever it updates Your program needs to wait for Gnuplot to do any of this in order to go to the next step All of these will greatly impact the amount of time you spend waiting for your data. You could potentially have it run every x iterations (eg. every 5 iterations), but even this wouldn't give you much of a speed-up.

I'm in the process of converting a large (several GBs) bin file to csv format using Python so the resulting data can be plotted. I'm doing this conversion because the bin file is not in a format that a plotting tool/module could understand, so there needs to be some decoding/translation. Right now it seems like Gnuplot is the way to go for such large data size. I'm wondering if instead of waiting for the whole file to finish converting and then running Gnuplot, is there a way to plot the data as it's being processed? Perhaps I could bypass the csv file altogether. Everything I've read so far points to plotting a file with data, but I have not seen any ways of plotting/appending individual data points.

How to install a library using homebrew

python,homebrew

As others mentioned already: It's not the best idea - at least not in general - to install python packages via your systems package manager. It's better to use pip (ideally in conjunction with virtualenvs). Apart from that, it should be possible to use the package you installed using homebrew from pycharm / python in general. In pycharm you can switch between different interpreters (Settings / Project / Interpreter). You need to to choose the one you installed the package for with homebrew (e.g. the one in /usr/local/Cellar/python//..). If you used brew link the currently active one should be symlinked to /usr/local/bin/python.

In pseudocode: Find all files in locations Source and Target. For each file in Source, calculate (checksum, size), and use this as a key in a dict, where the value is the filename. For each file in Target, calculate (checksum, size), and look it up in the dict created previously. If it exists, rename it.

Path a/b/c/d where folder d has a bunch of files and folders, something like this. Folder E which has abc.txt, def.jpg, and ghi.pst Folder D also has loose files like jkl.pst, mno.jpg, pqr.txt Path w/x/y/z where folder z has a bunch of folders named like a3cj85zblahblahblah asdfljklqwpeoriu833 Each of these folders contains a file, or files from one of the folders in path a/b/c/d. They are the same files except they've been renamed. So the file named abc.txt from a/b/c/d/FolderE is now in any folder in the path w/x/y/z renamed as bf6241b7c8b1.txt. I know it's the same file because I not only compared them but they also have the same modified date, type, and size. I was thinking about using os.rename and os.walk but I don't know where to start. I'm fairly new to Python and need to get this done ASAP in Windows.

Faster Google App Engine Managed VM deploys (Python compat env)?

Well, in general, 10 minute deployment isn't that bad. I use AWS Elastic Beanstalk and it's about the same for a full deployment of a production environment. However, this is totally unacceptable for your everyday development. Since you use docker, I really don't understand, why not to spin up the same container on your local machine and test it locally before releasing to staging? If that is not an option, for some reason, my second bet would be updating code directly inside the container. I've used that trick a lot. As Python a dynamic language, all you need just a fresh copy of your repo, so, you can ssh into your container and check out the code. That said, the feedback loop will be reduced to the time of committing and checking out the code. Additionally, if you set up some hooks on commit, you don't even need to check out the code manually. All in all, this is just my two cents and it would be nice to hear more opinions on that really important issue.

We're using Google App Engine (GAE) with Managed VMs for a Python compat environment, and deployments take too much time. I haven't done strict calculations, but I'm sure each deployment takes over 10 mins. What can we do to accelerate this? Is this more a GAE or a Docker issue? Haven't tried deploying Docker in other platforms so I'm not sure standard/acceptable deployment times. Having to wait so much to test an app in the staging servers damages our productivity quite a bit. Any help is appreciated. :)

Difference between os.mkdir(dirname) and os.mkdirs(dirname) mkdir() will create only neaded directory. If some of parent directories was not existing, mkdir() will return false. mkdirs() will create the last directory with all missing parent directories.so mkdirs() is more handy.

I use python 2.7 to create a spider in Pycharm to get data from website. In the first spider I create a spider in the project folder and use os.mkdir('home/img/') to create a folder to save data. There is no error. In the second spider I create the spider with RedisQueue which is in the project folder and put the Spider.py into /usr/lib/python2.7. when I use os.mkdir('home/img/') it reports the error 'no such file or dir' and I change it to os.makedirs() which works. May I know why the 1st one doesn't meet error? Thanks in advance

os.makedirs() : Recursive directory creation function. Like os.mkdir(), but makes all intermediate-level directories needed to contain the leaf directory. What this means is that you should not try to create nested directories with os.mkdir() but use os.makedirs() instead. In your case, I am guessing that you want to create a directory under your home directory, in which case you would need something like os.mkdir("/home/img"), which will fail if you do not have enough permissions. You could try and do something like: os.chdir('/home') and after that os.mkdir('img') so you create home/img in steps! Good luck!

You could create a cronjob that starts the script every 5 minutes (or whatever often you want it to run) and additionally modify the script such that it creates a .lock file which it removes on exiting, but if it encounters it at the beginning it won't do anything (this way you don't have a long-running script active multiple times).

Using CodeDeploy ValidateService Hook with Python Application

I would loop in the ValidateService hook, checking for the condition you expect, OR just sleep for 60 seconds, assuming that is the normal initialization time. The ValidateService hook should do just that: make sure the service is fully running before continuing/finalizing the deployment. That depends on your app of course. But consider a loop that pulls a specially designed page EG http://localhost/service-ready. In that URL, test and confirm anything and everything appropriate for your service. Return a -Pending- string if the service is not yet validated. Return a -OK- when everything is 100% Perhaps loop that 10-20 times with a 10 second sleep, and exit when it returns -OK- then throw an error if the service never validates.

I have an heavy app hosted on AWS. I use CodeDeploy & Code Pipeline (updating from github) to update the servers when a new release is ready (currently running 6 ec2 instances on production environment). I've setup the codedeploy to operate one-by-one and also defined a 300 seconds connection draining on the load balancer. Still, my application is heavy (it loads large dictionary pickle files from the disk to the memory), the process of firing up takes about ~60 seconds. In those 60 seconds CodeDeploy marks the process of deployment to an instance as completed, causing it to join back as a healthy instance to the load balancer - this might cause errors to users trying to reach the application. I thought about using the ValidateService hook, but i'm not sure how to in my case.. Any ideas on how to wait for a full load and readyness of the application before proceeding to the next instance? This is my current AppSpec.yml version: 0.0 os: linux files: - source: /deployment destination: /deployment - source: /webserver/src destination: /vagrant/webserver/src permissions: - object: /deployment pattern: "**" owner: root mode: 644 type: - directory - object: /webserver/src owner: root mode: 644 except: [/webserver/src/dictionaries] type: - directory hooks: ApplicationStop: - location: /deployment/aws_application_stop.sh BeforeInstall: - location: /deployment/aws_before_install.sh AfterInstall: - location: /deployment/aws_after_install.sh ApplicationStart: - location: /deployment/aws_application_start.sh

I compiled my Python GUI with Pyinstaller on Windows 10 but it seems like it cannot find my other script even though I provided the hard-coded absolute path to it (with r'"C:\Program Files...script path..."'). I even tried os.isfile (script path) but it returns False. The python script was compiled with pyinstaller --onefile --windowed --icon=iconimage.ico myscript.py from the command prompt. I use this same command on Ubuntu and the binary works just fine. I read something about Pyinstaller creating a temporary directory which I found, but I don't think it matters where it's running from as long as I give it the full path, so I'm thinking maybe I need more options when compiling? The GUI opens just fine. It's when it needs to call the script that it doesn't do anything. There are no errors when I run it from the command prompt. Please help!

I am debugging a Python code for Maya through the remote debugger in PyCharm. The remote debugger can catch breakpoints as expected if the code is run at the command line, but it fails to do that if the Python code is running inside Maya's Script Editor. The Python code is running on a Ubuntu machine while the PyCharm remote debugger is running on Windows. I launch Maya on the Ubuntu machine from the directory that contains the script. The path mapping of PyCharm is simply set to "." for the Windows path that contains the same python script. Can you help me with this problem? Thanks a lot.

How to control a Windows application from Python

python,windows,ui-automation

Normally, an application exposes a user interface (UI) for users, and an application programming interface (API) for programming. A human being uses keyboard and mouse to work with the user interface (UI) An application uses programming to work with the application programming interface (API) The UI is designed for humans, and the API is designed for computers. It is sometimes possible to use programming to control the user interface of another program -- so your program acts as if it were using the keyboard and mouse. This technique is often called "UI automation", and programs that do it are sometimes called "robots". It's a big topic, and it can be quite complex. It's almost always better to use an API instead if you can: it's faster, simpler, more reliable. If you do need to use UI automation, there are a few different tools that can help. You are asking about Python, so here are a few UI automation tools that work with Python: AutoIT is a standalone product, but you can use Python to script it. PyWinAuto is designed for use from Python. Sikuli uses computer vision to find parts of the screen. I believe it comes with a recording tool as well. Just to repeat: UI automation is weird and hard. If you can possibly use an API instead, your life will be much easier.

I wrote a PySide application that should run on python2.7, on window,Linux and Docker container. The application contains Qtooltip and specific eventFilter that catches HoverEnter\HoverLeave. The application works well on windows 10 and ubuntu 14.04 desktop but when trying to run it inside Ubuntu 14.04 container both features didn't work well: The tooltip - It would seem that the text is covered by other tooltip text or totally black. The eventFilter - The application can't get the hover event (didn't appear). The main difference that I saw was that when running on Ubuntu desktop, some GTk libraries are loaded to the python process (according to the maps files). I tried reproduce the problem by installing everything on Ubuntu server (without Gtk), and got the same effect as inside the container. Even after installing Gtk on the server, still no change. I think that I might have missed some dependencies, but can't find any documentation on the issue. Thanks in advance,

I'm using Tornado's AsyncHTTPClient to fetch a URL multiple times. I pass in a different callback with each request. If I send requests A, B (with associated callbacks Callback_A and Callback_B) to a URL, but the responses come back in the opposite order B, A. Should I expect the callbacks to be called in the order of Callback_A, Callback_B or will they get called in the opposite order? I'd like to have the callbacks called in the order of responses (so Callback_B, Callback_A). If that's not the default behavior is there a way to do that instead?

How to install pygame, cv2, anaconda, pip etc to any one version of python in ubuntu 14.04

python,pygame,ubuntu-14.04

First of all I want to thanks Bennet for responding to my question so that I was able to figure out what the problem was. Actually the problem was with aliasing. When I installed cv2 or pygame using apt-get, they were installed for default version but when I installed any package by downloading the installer first (like I installed anaconda), it was installed for python 2.7.11 because 'python' was aliased for this version(that is 2.7.11). So, basically make sure that the default version for which you want to install everything is the one which is aliased as 'python', and everything goes fine. I aliased 'python' for the default version and then installed anaconda via installer and now it has been installed default version.

I have Ubuntu 14.04 LTS. I guess different versions of python are pre-installed in Ubuntu 14.04. Right now when I type 'python' in terminal it opens python 2.7.11, but I guess the default version of Ubuntu 14.04 is 2.7.6. When I type /usr/bin/python it opens the default version. I know this can be done with making aliases. The real problem is, I have installed pygame, cv2 (that is for image processing) using apt-get. These are installed for default version of python i.e python 2.7.6. Also I have installed anaconda with python 2.7.11 using pip, but again 'pip' and anaconda are installed for 2.7.11. I know python 3 is also pre-installed there but I don't use it. Also I have no python version installed in user/local/bin.Now I want to know why this problem is occurring? How can I fix this now? Also how to import all the libraries for one python version(either default or another) and how to use it? How to configure my settings so that I would not have any problem in future?

python packages with dependencies in windows system

python,windows,pyffmpeg

You're basically asking how to quickly set up a development environment to compile a given project. You're generally at the mercy of the project developers and how well they documented the build process. On linux, you often have a package manager to make the installing and resolving of dependencies easy. Since Windows doesn't have a package manager, many popular projects with lots of dependencies will include a download link to a Libraries zip file that contains all the dependencies necessary to compile the source. Instead of running pip each time, it may be faster to just download the source to those python projects and run the setup.py manually, resolving dependencies until it succeeds. In general, for python libraries that wrap C/C++ libraries, you're not going to be able to build the python library if you can't build the corresponding C/C++ library. So, you may want to download the ffmpeg source and try compiling it first. Also, for some compiled python libraries, you may be able to find python wheels, which will contain pre-compiled binaries for your system, making the compile step unnecessary. If the python library wraps another C/C++ library, you'll still need to download and install the appropriate version of the library that it wraps (e.g. ffmpeg)

I am trying to work with python on a new project in my windows system. The project uses ffmpeg and pyrabin among others. I find it extremely difficult to move forward with pip installing these packages as they constantly keep on asking for missing dependencies. Following are some errors: ffvideo\ffvideo.c(254) : fatal error C1083: Cannot open include file: 'libavutil/rational.h': No such file or directory local\temp\pip-build-kvsijc\pyrabin\src\rabin_polynomial.h(38) : fatal error C1083: Cannot open include file: 'stdint.h': No such file or directory It is taking me forever to resolve each of them. Please advice on how to quickly resolve such missing dependencies. I tried google and it is full of options for linux systems. Any help would be highly appreciated.

Unfortunately you cannot do so directly at the moment. For the time being, you need to connect the Uno to some component which accepts messages from the Uno and can talk WAMP as well. We are working on a C library for lower-end devices, but as far as I can tell (I'm not directly involved) something with the specs of the Uno will remain out of the scope of WAMP even then since the initial plan is that the library itself will consume about 8k of RAM.

I am trying to install matplotlib into python27 but am running into issues with pip. As stated when I try any 'pip' command I get 'pip' is not recognized as an internal or external command. I checked my path variables and they point to the location of my OSGeo4W Python27 install. get-pip.py works and it even says I am up to date on my pip install. I am wondering if the issue is that I have more than one Python installed on my PC. Arc Desktop decided I needed C:\Python27 and C:\Python34 on top of the OSGeo4W install in the C:\OSGeo4W64\apps\Python27 Anyone know what the issue might be? Can I consolidate my python installs without breaking anything?

I have some packages installed under my ~/.local/lib/python2.7/site-packages/ subdir, which was for use with system python (/usr/bin/python). Now I have just installed Anaconda python (which is also python 2.7, but minor version 11). The whole idea of Anaconda distro is to have a self-containing python environment, such that EVERY module resides within anaconda install tree. But what annoys me is that for some reason I cannot disable inclusion of ~/.local/lib/python2.7/site-packages/ from sys.path although I did not have PYTHONPATH environment variable. Is it possible to run python executable (in this case, Anaconda's python executable) without having to implicitly add ~/.local/lib/python2.7/site-packages/ and the eggs underneath it in the python search path? Why this problem? Unfortunately the ~/.local/lib/python2.7/site-packages/easy-install.pth also contains a reference to /usr/lib/python2.7/dist-packages, which causes this system-wide dist-packages to still be searched for.

Depends on how and where you want to be able to access this cache in the future, and how you want to handle invalidation. If the CSV files don't change then this could be as simple as @functools.lru_cache or a global dict. If you need one cache shared across multiple processes then you could use something like memcached or redis, but then you'll still have some parsing overhead depending on what format you use. In any case, there's not really anything Tornado-specific about this.

I am running in Windows and have a git post-receive hook that calls a python 3 script. This Python script does a number of things. One of these is to output the username running the git hook. This username is MACHINENAME$ (where the machine name is MACHINENAME), which I think is the Network Service account, but I could be wrong here. After that it calls subprocess.run which execs a call to the ClearCase command clearfsimport. Note that I use the clearfsimport 'nsetevent' switch which does allow other users to check-in to this view, but this doesn't seem to work for the Network Service account. If I run the python command directly as the ClearCase view owner, the clearfsimport succeeds. If I run it as another user, the clearfsimport succeeds. If I run it as a git hook, however, it fails with the following error message: subprocess.CalledProcessError: Command '['clearfsimport', '-recurse', '-nsetevent', '-rmname', '-comment', "This is my comment", '/path/to/clearfsimport/source', '/path/to/ClearCase/view']' returned non-zero exit status 1 What can I do to get this git hook to work correctly? It does not matter if I have to adjust python, git, ClearCase, or Windows, or some combination.

I changed the environment variable PATH, to a new value and then back to what I believe was the original one. But now I can't open a .ipynb file through the Windows command line the was I was used to. After changing the directory in command line and running ipython notebook notebook_name.ipynb I get the following message: 'ipython' is not recognized as an internal or external command. My environment variable is set to a folder with python.exe, and this folder includes a subfolder with ipython.exe and jupyter-notebook.exe. When I open iPython command line and type %env, I can see the full path to the correct subfolder under PATH. Can someone point to a solution? Thanks.

Backing up and copying configs to server. Automate certain config changes to adhere to standards. Scripts to copy run start on all devices at will. Finding various config entries on all devices that may need to be altered. There are so many possibilities. Search github and pastebin and the overflow sites for anything using: Import netmiko Import paramiko Import ciscoconfparse Scripts using any of those libraries will be network related typically and offer up ideas.

I originally posted on his on Network Engineering but it was suggested that o post it on here. I've been learning Python and since I work in networking I'd like to start writing a few scripts that I can use in my day to day work tasks with switches. So my question is this, what network projects have you used python in? What sort of tasks have you written scripts for? I'm not asking for source code, I'm interested in what projects people have done to inspire my own coding adventures! Thanks all!

The simplest is to create a logic for a pool-of-ports manager ( rather avoid attempts to share / pass ZeroMQ sockets to / among other processes ) One may create a persistent, a-priori known, tcp://A.B.C.D:8765-transport-class based .bind() access-point, exposed to all client processes as a port-assignment service, to which client processes .connect(), handshake in whatever manner is needed to proof an identity/credentials/purpose/etc and .recv() in a coordinated manner one actually free messaging/signalling-service port number, that is system-wide guaranteed to not be used at the very moment / until returned to the port-manager ( a rotating pool of ports is centrally managed, under your code-control, whereas all the sockets, created locally in the distributed process(es)/thread(s) .connect() / .bind()-ing to the pool-manager announced port#, and thus will still remain, and ought remain, consistently within ZeroMQ advice, not to be shared per-se ).

I have a Python program which spawns several other Python programs as subprocesses. One of these subprocesses is supposed to open and bind a ZMQ publisher socket, such that other subprocesses can subscribe to it. I cannot give guarantees about which tcp ports will be available, so when I bind to a random port in the subprocess, my main program will not know what to tell the other subprocesses. Is there a way to bind the socket in the main process and then somehow pass the socket to my subprocess? Or either some other way to preregister the socket or a standard way to pass the port information from the subprocess back to my main process (stdout and stderr are already used by other data)? Just checking for a free port in the main process and passing that to the subprocess is not really optimal, because this could still fail if the socket is being assigned in the meantime. Also, since my program should work on Unix and Windows, I cannot really use ipc sockets, which would otherwise solve my problem.

I don't think keras is the only problem. If you are using theano as a backend, it will create $HOME/.theano/ as well. One dirty trick is to export HOME=/data/username/, but other program than keras or ipython will also treat /data/username/ as $HONE. To avoid that, you can do this locally by calling HOME=/data/username/ ipython or HOME=/data/username/ python kerasProgram.py.

When I'm in ipython and try to import keras, I get the error No space left on device: /home/username/.keras. How can I change this so that Keras does not use my HOME directory, and instead use /data/username/? I did the same for the directory ~/.ipython. I moved it to the desired location and then did export IPYTHONDIR=/data/username/.ipython, can I do something similar with Keras? More generally, how can I do this for any app that wants to use HOME? Note: Please don't give answers like "you can clean your home" etc. I am asking this for a reason. Thanks!

I got similar issue though I am not sure which platform you are using. Steps are: look for file _gdbm.cpython-"python version"-.so example file: _gdbm.cpython-39-darwin.so Once you find the path check which python version in directory path. Try creating same python venv. Execute your code. Before this make sure you have install appropriate gdbm version installed on host machine, for mac it's different for ubuntu it's different name.

In the Python 3 docs, it states that the dbm module will use gdbm if it's installed. In my script I use from dbm.gnu import open as dbm_open to try and import the module. It always returns with the exception ImportError: No module named '_gdbm'. I've gone to the gnu website and have downloaded the latest version. I installed it using ./configure --enable-libgdbm-compat, make; make check; make install, and it installed with no errors. I can access the man page for the library but I still can't import it into Python 3.5.2 (Anaconda). How do I install the Python module for gdbm?

python subprocess pipe unbuffered behaviour

python,pipe,subprocess,buffer

Answering to your questions: No, it will not be stored in memory. The child process will stuck on write operation after exceeding pipe-max-size limit (cat /proc/sys/fs/pipe-max-size); The child process will write about 1M before it will stuck, until the parent process read block of data. After this child process will write next 1024 bytes sequentualy as fast as they will be readed; Yes in case of blocking IO the process will be blocked by the OS when write syscall will be called. In case of non-blocking IO I hope write syscall will return EAGAIN or other system-specific error. So actually the application will stuck while calling write system call waiting for the pipe buffer will available. It doesn't mean that it will hang. For example if an application implements some kind of internal queue and it have more than one thread, it can continue to work and add any data to it's queue while the writting-out thread will wait for the buffer.

I've the below piece of code to read data from a child process as its generated and write to a file. from subprocess import Popen, PIPE proc = Popen('..some_shell_command..', shell=True, stdout=PIPE) fd = open("/tmp/procout", "wb") while True: data = proc.stdout.read(1024) if len(data) == 0: break fd.write(data) fd.close() 'Popen' default bufsize is 0 => unbuffered. What will happen if for some reason the write-to-file operation experiences a huge latency? Assuming that the child process is supposed to produce 500GB of data, do all those data get stored in memory until the parent reads them all? (OR) Will the child process wait for 1024 bytes of data to be read by the parent before writing the next 1024 bytes to stdout? (OR) Will the child process wait after the OS pipe buffer gets filled and once the parent reads, the child resumes writing again? (OR) ??

Currently, I open this file as such; open(..\\DataSubDirectory\\data.txt) Is there a method by which I can set any file paths within my TestFile.py to be relative to the parent project folder, so that if the file were moved to another Sub Directory, or placed in the parent directory even, I would not get a filepath error? The effect being that any file opened as such; open(data\\data.txt) would actually be opened as open(PythonProject\\data\\data.txt), and not relative to whichever directory it is found?

Archiving a group of gzipped files

python,compression,gzip,tar,gzipstream

A gzipped tar archive is not an archive of compressed files. It is a compressed archive of files. In contrast, a zip archive is an archive of compressed files. An archive of compressed files is a better archive format, if you want to be able to extract (or update) individual files. But it is an inferior compression technique; unless the component files are mostly quite large or already compressed, compressing the files individually results in quite a bit more overhead. Since the primary use case of gzipped tar archives is transmission of complete repositories, and the entire archive is normally decompressed at once, the fact that it is not possible to decompress and extract an individual file [Note 1] is not a huge cost. On the other hand, the improved compression ratio brings a noticeable benefit. To answer the question, the only way to combine multiple gzipped tar archives is to decompress all of them, combine them into a single tar archive, and then recompress the result; option 1 in the original post. Notes Of course, you can decompress the entire archive and extract a single file from the decompressed stream; it is not necessary to save the result of the decompression. The tar utility will do that transparently. But under the hood, the archive itself is being decompressed. It is not even possible to list the contents of a gzipped tar archive without decompressing the entire archive.

I have a group of about 10 gzipped files that I would like to archive into a single file in order for a user to download. I am wondering what the best approach to this would be. Gunzip everything, then tar-gz the complete set of files into a myfiles.tar.gz? Tar the set of gz files into a myfiles.tar. Option 1 seems to have unnecessary steps as the original files are already compressed. Option 2 seems confusing because there is no indication that the files inside the archive are indeed compressed. How do people usually deal with archiving a group of already compressed files? I am using Python (if it matters), but I am doing the operations via shell executions.

python,macos

Don't! The name /Library and /System suggest that they are OS-level directories. Nobody installed them. Instead, Mac and other linux-based systems use them by default for system-level services (and they should not be even manually upgraded or system stability may suffer). For all what matters, you should just prepend your installation directory to a system variable called PATH in your $HOME/.bashrc file. Then, whenever YOU use python, the system will always search for the first occurrence of python on PATH, which is your python. Open terminal, enter the following command (once in a life time): echo "PATH={a-path-to-the-folder-containing-your-executable-python}:\$PATH" >> $HOME/.bashrc To explain it, the quoted command prepends your installation directory as the first place to search for executable files. The >> $HOME/.bashrc write this command to the last line of .bashrc, which is a file that setup your terminal environment automatically upon login.

Don't remove the system Pythons. They may be used by other programs. (I don't know if anything on OS X actually uses them, but it's best to keep them.) Instead, just make sure that your MacPorts bin directory (at /opt/local/bin) is first on your $PATH.

I think the best if you run Errbot in a container is to run it with a real database for the persistence (redis for example). Then you can simply run backup.py from anywhere (including your dev machine). Even better, you can just do a backup of your redis directly.

I have written a mapper program in python for hadoop Map-Reduce framework. And I am executing it through the command: hadoop jar /usr/hdp/2.3.2.0-2950/hadoop-mapreduce/hadoop-streaming.jar -mapper "python wordcount_mapper.py" -file wordcount_mapper.py -input inputfile -output outputfile3 It is working properly if the directory inputfile contains only file. But it is not working and showing error if there is sub directories into the directory inputfile . Like i have two sub directory in (KAKA and KAKU) in inputfile. And the error is showing : 16/07/20 17:01:40 ERROR streaming.StreamJob: Error Launching job : Not a file: hdfs://secondary/user/team/inputfile/kaka So, My question is that what will be the command to reach the files into the Sub Directory.

Not sure if this qualifies as a solution. I submitted the same job using dataproc on google platform and it worked without any problem. I believe the best way to run jobs on google cluster is via the utilities offered on google platform. The dataproc utility seems to iron out any issues related to the environment.

I'm currently using a Jenkins build to run a bash command that activates a Python script. The build is parametrised, and i need to be able to set environment variables containing those parameters on the Windows slave to be used by the Python script. So, my question is: How do i set temporary env. variables for the current build and secondly, how do i use Python to retreive them while running a script? An explanation of the process would be great since i couldn't make any solution work.

We have implemented a simple DynamoDB database that is updated by a remote IoT device that does not have a user (i.e. root) constantly logged in to the device. We have experience issues in logging data as the database is not updated if a user (i.e. root) is not logged into the device (we log in via a ssh session). We are confident that the process is running in the background as we are using a Linux service that runs on bootup to execute a script. We have verified that the script runs on bootup and successfully pushes data to Dynamo upon user log in (via ssh). We have also tried to disassociate a screen session to allow for the device to publish data to Dynamo but this did not seem to fix the issue. Has anyone else experienced this issue? Does amazon AWS require a user (i.e. root) to be logged in to the device at all times in order to allow for data to be published to AWS?

Looks like that in newer versions of Jupyter the changes that should be done in the configuration is a little different from the above answers (otherwise you can get error "'' does not appear to be an IPv4 or IPv6 address"). The entire solution: Run: jupyter notebook --generate-config Change in the config the bellow: c.NotebookApp.ip = '0.0.0.0' c.NotebookApp.open_browser = False Now you can run Jupyter simply: jupyter notebook

For my case (using VMware with Ubuntu), the solution was very simple. By default, the network adapter was already in NAT mode. If not, adjust this in the settings of your VM instance. Type ifconfig in a VM terminal to get your local IP, e.g. 192.168.124.131. Start the notebook: jupyter notebook --ip=192.168.124.131 --no-browser The terminal then gives you a link you can use on the host to access jupyter, e.g. http://192.168.124.131:8888/?token=xxxxxxxxxxxxxxxxxxx.

Unexpected socket.getaddrinfo behavior in Python using SOCK_STREAM

python,sockets,python-3.x,getaddrinfo

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?

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?

Using command line args from different files in python

38,621,007

0

275

0

python,command-line-arguments

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.

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?

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.

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?

Hendrix is a WSGI compatible server written in Tornado. I was wondering if it can be used to run an app written in Falcon ?

You may try to use which python to find out the location of python in your computer. If it doesn't work and you cannot find where is the your installed directory, you may need to reinstall and make sure you remember the installation directory and add it as a environment variable in windows system.

I have installed Python 3.5.2 on my windows 8 computer, I tried in cmd python --version and it gave me that stupid error: "python is not recognized as an internal or external command..." I also have no files named python on my computer anywhere. I used the search feature on file explorer and I've search manually. I even looked through the hidden files. I have tried to install Python 3 times and the same thing keeps happening. Any help appreciated.

In Windows 8 for Python 3.* I believe it is: C:\Users\yourusername\AppData\Local\Programs\Python\ To use that from the Windows command line you will need to add it to your path. Control Panel -> Advanced System Settings -> Environment Variables -> System Variables -> Path Add in the Python path at the end after a semi-colon, do not delete the others.

Django: Know when a file is already saved after usign storage.save()

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!

Send commands to running script by running it with flags

There are two things this needs to do: you need to handle command-line flags, and you need to send signals to another process. For the flags, you could use the argparse library, or simply sys.argv. For sending signals, you will need the Process ID (pid) of the already running process. Under Linux you can call ps, and check to see if there is another instance of the script running. If there is, send it a signal. Another alternative to signal handling is DBus. This is less cross-platform capable, though.

I'm trying to make a python script run in the background, and listen to commands. For example if I run my script: python my_script.py it will start running (and wait for commands). Then I wish to run: python my_script.py --do_something, open a different python process, and it will run a function do_something() in the previous process. I've seen this works on programs like PDPlayer where the flag --play causes the player to start playing a video. Can this also be done in python? I know how to handle the command line arguments using argparse. I need help regarding the communication between the two python processes. Also, I plan to cx_freeze the app, so the PID of the app can be found using psutil by searching the executable name. Thanks. btw, I'm using Windows...

Service inside docker container stops after some time

Consider doing a docker ps -a to get the stopped container's identifier. -a here just means listing all of the containers you got on your machine. Then do docker inspect and look for the LogPath attribute. Open up the container's log file and see if you could identify the root cause on why the process died inside the container. (You might need root permission to do this) Note: A process can die because of anything, e.g. code fault If nothing suspicious is presented in the log file then you might want to check on the State attribute. Also check the ExitCode attribute to see if you can work backwards to see which line of your application could have exited using that code. Also check the OOMKilled flag, if this is true then it means your container could be killed due to out of memory error. Well if you still can't figure out why then you might need to add more logging into your application to give you more insight on why it died.

I have deployed a rest service inside a docker container using uwsgi and nginx. When I run this python flask rest service inside docker container, for first one hour service works fine but after sometime somehow nginx and rest service stops for some reason. Has anyone faced similar issue? Is there any know fix for this issue?

Google App Engine - run task on publish

The main question will be how to ensure it only runs once for a particular version. Here is an outline on how you might approach it. You create a HasRun module, which you use store each the version of the deployed app and this indicates if the one time code has been run. Then make sure you increment your version, when ever you deploy your new code. In you warmup handler or appengine_config.py grab the version deployed, then in a transaction try and fetch the new HasRun entity by Key (version number). If you get the Entity then don't run the one time code. If you can not find it then create it and run the one time code, either in a task (make sure the process is idempotent, as tasks can be retried) or in the warmup/front facing request. Now you will probably want to wrap all of that in memcache CAS operation to provide a lock or some sort. To prevent some other instance trying to do the same thing. Alternately if you want to use the task queue, consider naming the task the version number, you can only submit a task with a particular name once. It still needs to be idempotent (again could be scheduled to retry) but there will only ever be one task scheduled for that version - at least for a few weeks. Or a combination/variation of all of the above.

I have been looking for a solution for my app that does not seem to be directly discussed anywhere. My goal is to publish an app and have it reach out, automatically, to a server I am working with. This just needs to be a simple Post. I have everything working fine, and am currently solving this problem with a cron job, but it is not quite sufficient - I would like the job to execute automatically once the app has been published, not after a minute (or whichever the specified time it may be set to). In concept I am trying to have my app register itself with my server and to do this I'd like for it to run once on publish and never be ran again. Is there a solution to this problem? I have looked at Task Queues and am unsure if it is what I am looking for. Any help will be greatly appreciated. Thank you.

Personally, this makes more sense to me as a responsibility of your deploy process, rather than of the app itself. If you have your own deploy script, add the post request there (after a successful deploy). If you use google's command line tools, you could wrap that in a script. If you use a 3rd party tool for something like continuous integration, they probably have deploy hooks you could use for this purpose.
