Rodrigo Murta 2014-07-15T01:24:06Z https://community.wolfram.com/groups/-/m/t/1884517 I am a Data Scientist working in a startup in Brazil. Recently I was working with Social Networks in Python using networkx library to analyse posts from a given hashtag for our client. However, I was completely aware of the additional functionalities of Wolfram Mathematica. Take the following picture as an example, done with networkx, 100,000 people: ![Social Network Emotions Connections][1] It's an interesting perspective, but adds little value to generate strategic insights for our clients, given that we need to zoom it to analyze details of this network. In my previous experience of Wolfram Mathematica, I was able to use some reasoning coming from cellular automata interactions to map, track people of interest (blue circle), and watch the evolution of mood (color), number of connections (size of circle) in a social network: ![Evolution of Mood][2] Besides, one can use Mathematica's features of finding communities, coloring them and even highlight people of interest when passing the mouse over the social network and also speaking their names: ![Communities][3] More than that, you can highlight communities and check the number of connections of each individual: ![Communities Two][4] So, it's clear that Wolfram Mathematica is way ahead of networkx. However, I was dealing with a drawback: if you choose to plot more than 10,000 connections in Mathematica, that can take some time. And time is what you don't have in a startup. So, I started wondering how I could use GPUs with Wolfram Mathematica. One way it's to use webMathematica, installing Java and Apache Tomcat in a cloud instance. However, I was told one can also use Wolfram Client Python library and run Mathematica in a Python notebook. So, I will present how I was able to run Mathematica inside a Jupyter notebook located in a Google Cloud instance with 8 V100 GPUs. My co-worker, Gustavo Gouvea, also put efforts in this solution. First of all, go to Google Cloud Platform (GCP) Compute Engine and select Create Instance in a given region. Choose your CPUs, Memory, GPUs and regarding the boot disk, I used Debian GNU/Linux with Anaconda, PyTorch and CUDA already installed, as we also work with Deep Learning and NLP. After that, you need to configure Jupyter in order to be able to open it in the local browser, by doing the following: ipython from IPython.lib import passwd passwd() Now that you created the password, you are going to save "sha1:49b8799c22..." Then you will edit Jupyter configuration file (use sudo or chmod -R 777 /home/anaconda3): sudo vi ~/.jupyter/jupyter_notebook_config.py Add (type "i") these line of code: c=get_config() c.NotebookApp.password = paste your sha1 here c.IPKernelApp.pylab = 'inline' c.NotebookApp.ip = "*" or 0.0.0.0 c.NotebookApp.open_browser = False Go to GCP VPC and create a static IP for your instance, SSH into it. So, to start Jupyter notebook you will need to run: jupyter notebook ![Jupyter][5] Now you will access Jupyter in the following address: http://http://55.100.30.200:8888/ ![Jupyter 2][6] That will allow you to run Python notebooks in Jupyter. Now Mathematica. Get the mathematica .sh file: sudo wget link_to_mathematica.sh To install Mathematica run in another SSH session (terminal window): sudo bash link_to_mathematica.sh Ok, you installed Mathematica. Now run: math This command will ask for your Activation key and Password. After providing them, Mathematica notebook starts in the command line ![Mathematica running][7] **Important:** You must run Mathematica ("math") **before** you open Jupyter Notebook. Now that you've opened Mathematica in the command line with one SSH and after that Jupyter Notebook in other SSH, access the web address, port 8888, create a new Python 3 notebook and install wolframclient library: ![pip install][8] Now you can run your Mathematica scripts with backup of how many GPUs you need: ![NVIDIA-SMI][9] from wolframclient.language import wl as w1 from wolframclient.language import wlexpr from wolframclient.evaluation import WolframLanguageSession session = WolframLanguageSession('/usr/local/Wolfram/Mathematica/12.0/Executables/MathKernel') import numpy as np import imageio import matplotlib.pyplot as plt from PIL import Image ![Output][10] In bird's eye: ![Overview][11] ![enter image description here][12] The only point is that you won't have access to all Mathematica functionalities, as Manipulate, Mouse Over and the display of some images when output is truncated. My guess is that init.m config file must be adjusted to increase output size before truncation (in the command line) : ![GraphPlot][13] [1]: https://community.wolfram.com//c/portal/getImageAttachment?filename=Easter0.PNG&userId=992056 [2]: https://community.wolfram.com//c/portal/getImageAttachment?filename=0.jpeg&userId=992056 [3]: https://community.wolfram.com//c/portal/getImageAttachment?filename=01.png&userId=992056 [4]: https://community.wolfram.com//c/portal/getImageAttachment?filename=02.png&userId=992056 [5]: https://community.wolfram.com//c/portal/getImageAttachment?filename=2918jupy.png&userId=992056 [6]: https://community.wolfram.com//c/portal/getImageAttachment?filename=jupyter.png&userId=992056 [7]: https://community.wolfram.com//c/portal/getImageAttachment?filename=pp.png&userId=992056 [8]: https://community.wolfram.com//c/portal/getImageAttachment?filename=pip.png&userId=992056 [9]: https://community.wolfram.com//c/portal/getImageAttachment?filename=nvidia.png&userId=992056 [10]: https://community.wolfram.com//c/portal/getImageAttachment?filename=py.png&userId=992056 [11]: https://community.wolfram.com//c/portal/getImageAttachment?filename=bird.png&userId=992056 [12]: https://community.wolfram.com//c/portal/getImageAttachment?filename=sss.png&userId=992056 [13]: https://community.wolfram.com//c/portal/getImageAttachment?filename=issues.png&userId=992056 Rubens Zimbres 2020-02-21T00:39:03Z https://community.wolfram.com/groups/-/m/t/613588 Since there are many folks on this forum that are new to using Mathematica/WolframLanguage I'd suggest that each order a copy of Stephen Wolfram's soon-to-be-released (December 7 2015) "An Elementary Introduction to the Wolfram Language": [http://www.amazon.com/Elementary-Introduction-Wolfram-Language/dp/1944183000/][1] though I haven't read it yet, there is a clear need for a tutorial that helps beginning users "start right" and avoid the many issues that arise by simply diving in without a helping hand to get the basics in place. Also another excellent book (but which assumes a certain amount of exposure to scientific, engineering and mathematical subjects but no knowledge of *Mathematica* and very little if any of programming in general) is Paul Wellin's "Programming with Mathematica®: An Introduction", which I have read. [http://www.amazon.com/Programming-Mathematica-Introduction-Paul-Wellin/dp/1107009464/][2] So, beginners, get a couple of good introductions to Mathematica and dive in to learning the language!

Bjorn Cole 2013-07-24T15:00:15Z https://community.wolfram.com/groups/-/m/t/908444 Abstract ======= Have you ever thought which place could be the best for sky observation? When should you enjoy clear sky? A lot people like astronomy and usually they observe astronomical objects using telescopes or camera. Star observers and photographers should know the importance of the clear sky during an observation of astronomical objects such as the moon. The moon is the brightest object in the sky and it is the main reason why I started my project with creating an astronomical web program which will show the weather forecast by comparing it with other regions in a chosen country and also the moon phases for the next week. Firstly, users will get an opportunity to observe the moon from their window or in the parks near to their home. Secondly, they will get information about regions where cloud density is the lowest. Finally, users will know the moon phases for the next week so they can use it for an observation. In this case it becomes easy to observe astronomical objects without having problems with the cloudy sky and the location choice. Table of Context -------------------- - **Introduction to Astronomy Club Bot program** - **Searching for Wolfram Data** - **Creating Data Access Library** - **Integrating Library into a Single Macro-Function** - **Creating Cloud Micro-Site** - **Conclusion** Please interact with the actual web project at the [**following location**][1] ![enter image description here][2] #Introduction to Astronomy Club Bot program Astronomy Club Bot program has three inputs and a big output, which includes three important parts. First input is the name the of city where user wants to observe the Moon. The output has two parts related to each other. It shows the cloud cover and the moon phases for that week. Second and third inputs are the name of the country and the exact date of an observing. Third part shows map with the comparison of the cover densities in all regions of a chosen country. The main thing that I used during programming was the Wolfram Data and all functions related to my web project. Wolfram Data used ======= - WeatherForecastData - CloudCoverFraction - AdministrativeDivisionData - CountryData - CityData - Date - MoonPhase Creating Data Access Library ======= After researching all important information I started to code a simple functions and the Wolfram data helped me. Here is my first plot (part of the main output) which shows the cloud cover for 6 days in a chosen city. That is why I used CloudCoverFraction to got the cloud cover information. cit[x_] := DateListPlot[ WeatherForecastData[GeoPosition[x], "CloudCoverFraction"], PlotRange -> All, Mesh -> All, Filling -> Bottom] cit[Entity["City", {"Kathmandu", "Kathmandu", "Nepal"}]] ![enter image description here][3] This is my second plot, which I connected with the first one (next output shows that). I used the MoonPhase function to got the illustration of the moon phase fraction for a current date. According to my written code the program counts days by assuming that the first day will be tomorrow (first=Tomorrow) so it adds the next 6 days to it and shows the moon phases for that days . mn = Grid[{{ImageResize[#2, 35]}, {DateString[#, {"DayShort"}]}}] & @@@ MoonPhase[ With[{first = Tomorrow}, DateRange[first, DatePlus[first, Quantity[6, "Days"]]]], "Icon"][ "Path"] Integrating Library into a Single Macro-Function ======= Here I connected two simple functions by using Grid function and gave them sizes .In that case I have two parts in the one output. That means my program will take the city name and give me information about the cloud density and also the moon phases for 6 days. tg[y_] := Grid[{{Row[mn, Spacer[9]]}, {Show[cit[y], ImageSize -> 400]}}] ![enter image description here][4] The AdministrativeDivisionData function helped me with the comparison of a regional cloud covers. The benefit of this data was that I found administrative divisions of all needed countries by using EntityList and EntityClass. div[z_] := EntityValue[ Entity["AdministrativeDivision", {EntityProperty[      "AdministrativeDivision", "ParentRegion"] -> z}], "Entities"] I made a function with WeatherForecastData for cloud cover prediction of the exact time.In this function I have two arguments, so they are responsible for the Date and the GeoPostion. wt[time_][ad_] := QuantityMagnitude[ WeatherForecastData[GeoPosition[ad], "CloudCoverFraction", time]] The pltF function shows a regional plot with administrative divisions and the main argument depends on the exact date and the country that user should input. I used a "ct" argument which I defined by mapping a "wt" and a "region" functions. pltF[y__, ct_] := GeoRegionValuePlot[Thread[y -> ct], PlotStyle -> Opacity[.5], GeoBackground -> "StreetMap", PlotLegends -> Placed[Automatic, Above], ImageSize -> 400]; mapperFunct includes two arguments and makes easy to get a division plot that shows the comparison of the cloud covers for each region. This plot is evaluating by getting information of date and position. mapperFunct[country_, time_] := Module[ {regions, ct, ans}, regions = div[country]; ct = wt[time] /@ regions; ans = pltF[regions, ct]; ans ] mapperFunct[Entity["Country", "Nepal"], Tomorrow] ![enter image description here][5] Creating Cloud Micro-Site ======= In finalFunct I added all important functions that I programmed before. My function has 3 inputs with big output as I wanted. It means my function runs by depending on 3 arguments. finalFunct[city_, country_, time_] := Rasterize[Column[{tg[city], mapperFunct[country, time]}], "Image", "ImageSize" -> 800] This is my final code of the web project where I used CloudDeploy function and included FormPage with 3 inputs. I changed my function permissions to Public, it means that program is opened for users so they can run my program and check the weather forecast for the moon observation. CloudDeploy[ Delayed[ FormPage[{ "city"-><|"Interpreter"->"City","Input"->"Kathmandu"|>, "country"-><|"Interpreter"->"Country","Input"->"Yerevan"|>, "date"->List[With[{first=Tomorrow},DateRange[first,DatePlus[first, Quantity[6,"Days"]]]]]}, finalFunct[#city,#country,#date]&]], "AstroClub",Permissions->"Public"] Conclusion ======= Astronomy Club Bot program gives an opportunity for amateur astronomers to take pictures and observe the moon with telescope or camera. Users will know the moon phase and the weather forecast by choosing the exact day when they want to organize observation. They also can go to another region where the cloud density will be the lowest. The main idea of this project was making an observation more comfortable for users who can't leave his/her home or region. So I programmed it by using simple functions,wolfram data and documentation.

Any advice on how and which platform to code on? Thanks in advance Arvind Rajan Arvind Rajan 2013-12-21T10:50:32Z https://community.wolfram.com/groups/-/m/t/206834 I would like to create a simple RESTful web service interface to publish a particular, complex calculation implemented in a Mathematica program to other external programs. I am thinking something along the lines of the [url=http://geocoder.us/help/utility.shtml]geocoder ZIP-code distance calculator[/url] example, easy to call via URI and passing an array of numbers as parameters (matrix algebra). I have seen the [url=http://reference.wolfram.com/mathematica/WebServices/tutorial/Introduction.html]Web Services documentation[/url] on Wolfram's reference for Mathematica 9. It seems to be a bit dated (2008) and geared towards SOAP 1.1. Also, the tutorials are generally describing the scenario where Mathematica is consuming an external web service as a client, as compared to offering a web service as Provider to external systems. I did not find any reference to a REST web service built with Mathematica either. Any pointers or example code would be appreciated. Thanks, Thomas. Thomas Laussermair 2014-02-23T20:04:15Z https://community.wolfram.com/groups/-/m/t/309979 Software titles are usually not written in italics (e.g. "Microsoft Word"), but *Mathematica* always seems to be italic. Is there any reason for this, or is just the Wolfram house style? (I promise this question isn't completely irrelevant! I haven't been able to find the answer anywhere else, so I thought I'd ask here.) Thanks Tim Carruthers 2014-08-01T00:53:44Z https://community.wolfram.com/groups/-/m/t/107541 Hello I have some questions as follows : Is it possible that the clients can view the result without installing the CDF Player?

Regards Gautam Gautam ANAND 2015-10-23T10:29:06Z https://community.wolfram.com/groups/-/m/t/517557 It seems that DateListPlot when used in webMathematica (3.3.1) show different output than in desktop Mathematica (10.1). In desktop Mathematica, if you evalutate data = {{{2015, 1}, 10}, {{2015, 2}, 6}, {{2015, 3}, 15}}; DateListPlot[data] will show this picture: ![desktop Mathematica output][1] in webMathematica instead, when you call this code (html removed for clarity) in .jsp file from your browser <msp:evaluate> data = {{{2015, 1}, 10}, {{2015, 2}, 6}, {{2015, 3}, 15}}; MSPShow[DateListPlot[data]] </msp:evaluate> it will show the graph without the vertical and horizontal Ticks: ![webMathematica .jsp output][2] Then I've tried to add FrameTicks -> True (and Frame-> False otherwise it doesn't show them) <msp:evaluate> data = {{{2015, 1}, 10}, {{2015, 2}, 6}, {{2015, 3}, 15}}; MSPShow[ DateListPlot[data ,Frame-> False ,FrameTicks -> True]] </msp:evaluate> the output now shows the ticks, but in Scientific Notation. No way to display the ticks in date format: ![enter image description here][3] It appears as a bug for me, because other functions as Plot[] or ListPlot[] produce a regular output. This strange behavior seems to be peculiar to DateListPlot[]. Does anyone has encountered the same problem or found a workaround? *(I've posted this question also on [StackExchange][4] )* [1]: /c/portal/getImageAttachment?filename=g1.MMA.gif&userId=332859 [2]: /c/portal/getImageAttachment?filename=g1.webMMA.gif&userId=332859 [3]: /c/portal/getImageAttachment?filename=g2.webMMA.gif&userId=332859 [4]: http://mathematica.stackexchange.com/questions/86647/datelistplot-in-webmathematica-doesnt-show-frameticks-properly Guido Tripaldi 2015-06-23T15:38:45Z https://community.wolfram.com/groups/-/m/t/471455 Mathematica has pretty nice support for reactive GUI creation and database connectivity. It seems that it would be suitable for writing database front-ends, especially those involving a lot of computation, graphs etc. Sadly, I've failed to identify a reasonable way to deploy such applications. If it's a bad idea to try using Mathematica for writing such applications, please tell me. Otherwise I'd like pointers as to a reasonable deployment strategy. Here is a list of the options I've considered and why I consider them unreasonable or problematic. 1) Write the application using Mathematica. To deploy, let every client install Mathematica, get a copy the notebook and run the application using Mathematica. This would be pretty hefty priced, since there would be a license fee for every single client using nothing from Mathematica except running this application. Maybe not unreasonable, but if there are better ways I'd like to know. 2) Write the application in Mathematica, then deploy using the CDF technology. Numerous sources indicate the CDF player for security reasons is unable to read or write external files. I suppose connecting to external, custom data sources is likewise restricted. I'm trying to deploy an application, not deliver a document, and since CDF is a "computable document format" I should probably take a hint. A database application not able to connect to it's data source is unreasonable. Also, having an application require the user to "allow unsafe whatever" every time it starts is, if not unreasonable, at least a major nuisance. 3) Write the application using Wolfram programming cloud. I've failed to build user interfaces using this product. Wolfram support tell me that "Mathematica Online, which is a Beta product, does not support the function Dynamic yet. Some Mathematica functionality is only supported in Wolfram Desktop systems as of now." Building Mathematica GUI without Dynamic is what I consider unreasonable. Also, I'm not exactly sure to what extent database connectivity is supported in Mathematica Online or Wolfram Programming Cloud (they are essentially the same product, right?) 4) Write the application using webMathematica. Haven't tried it, but is there any reason to believe it would work better than programming cloud? 5) Use the wolfram language server-side, but not for client GUI. This is probably viable, but would be a sad choice if you like the Mathematica GUI and graphs. Especially since the technology is there. Again, I don't know if the area of DB front-ends simply isn't targeted by Wolfram, but I assume there are countless other areas where you'd have the need to deploy a computing application with both GUI and file/data access. Delivering a top-notch product with [insert your favorite Wolfram sales video] and not providing a reasonable way for deploying applications, is what I consider unreasonable. M G 2015-04-01T14:08:10Z https://community.wolfram.com/groups/-/m/t/2672853 I wanted to compare those two solutions, so I started a free trial for both of them. However, it looks like they're completely the same. Wolfram Mathematica web opens the same website as Wolfram One web, and both of the desktop downloads download the same application. So what is the difference between those two? Are they just the same thing, but with different pricing models?
