Look at this: What I am supposed to do? I also tried by downloading the CUDA packlets: change nothing. I have an NVIDIA RTX 3090 and the drivers are ok. Thank you foe helping me. Regards to all, Jean-Michel Jean-Michel Charles Collard-Richard 2020-12-18T02:04:15Z https://community.wolfram.com/groups/-/m/t/1807709 Hello everybody! I wrote a number of notebooks calling R packages. But using up-to-date versions (Mathematica 12 and R 3.6.1), nothing works any more! For instance, it seems the default distribution doesn't exist now: In[2]:= InstallR[] REvaluate["sample(1:100,10)"] During evaluation of In[2]:= InstallR::invldrhome: The specified path to R home directory does not point to a valid directory Out[2]= $Failed I tried to use my own distribution, but it is not recognized! In[4]:= InstallR["RHomeLocation" -> "C:/PROGRA~1/R/R-36~1.1", "RVersion" -> "3.6.1"] During evaluation of In[5]:= InstallR::fail: Failed to install R. The following error was encountered: crash in low-level RLink component or in R runtime Out[5]= $Failed It seems there is an issue with the R.dll file (dll: 3.6.1, expecting 3.5.0). What can I do? Install an older version of R? Which one? Best regards, Claude Claude Mante 2019-10-15T09:19:47Z https://community.wolfram.com/groups/-/m/t/1175780 I have some code I'd like to reuse in multiple notebooks. Simple definitions, like ratioFromDb[db_] := 10^(db / 20) I expect I should put these definitions in their own file, and then somehow include that file in various notebooks. What are the details for this process, please? I have researched this in the documentations, and I've probably already seen the correct answer there, but I'm still not sure about this. My best guess is, put my library in a regular .nb file, and then invoke the library like this: Once[Get["myLibrary.nb"]] Do I have it right? If not, if someone could direct me to the specific page or section in the documentation that covers this, I'd appreciate it. Thank you. Anonymous User 2017-09-03T00:08:28Z https://community.wolfram.com/groups/-/m/t/1321057 This is a cautionary tale for those who choose Mathematica as the main tool for their work. It is now clear to me that Wolfram has simply abandoned the [Graphs and Networks](http://reference.wolfram.com/language/guide/GraphsAndNetworks.html) functionality area and I am left high and dry. I have no recourse because Mathematica is closed source so there is only so much a user can do to fix or work around problems. Reporting bugs in this particular area has now clearly proven to be useless. Most simply do not get fixed, no matter how serious they are, or how great a hindrance they are to practical use. No new functionality has been added since version 10.0. My colleagues who use other tools (mostly Python and R packages) are more productive at this point, but I have a handicap with those systems because I made the mistake of investing most of my time into Mathematica, and stayed optimistic about it even in the face of the most obvious warning signs. I am writing this post because those people who have not heavily invested in Mathematica, and in particular this functionality area of Mathematica, are not in a position to see this and may fall in the same trap I did. What if the same thing happens to the functionality area that is critical to *your* work? Wolfram Research, of course, will not tell you that they gave up on `Graph`. Thus, after my experience, I think I owe it to the community to warn you about the situation. ---- Some might ask me what specifically is wrong. I have made many posts on this forum about `Graph`-bugs (you only have to search), and I reported many more to WRI. There is always a last straw—it would be pointless to show it. Those who know me will know that I am not writing this admittedly emotional post out of ill will towards WRI. I have betted on Mathematica more than most, and have been advocating for it throughout the years. I even have a network analysis package with ~250 functions. If I am forced to abandon Mathematica for this type of work, then the countless hours that went into this package will all have been in vain. I admit that I am writing this public post partly out of desperation to try to get WRI to either fix the many serious `Graph`-problems, or otherwise publicly state that `Graph` is now abandoned so those of us who have been using it can stop wasting our time.

I have always found that the directions don't work for me, even though I have tried time and again to follow them closely and to try different ways of loading them. I have always had to resort to opening the package and executing it before I could use the package functions in a Mathematica notebook. I am making another try now. The first file is a package. The second file is a notebook that should load the package. It appears that the names of the symbols load into the second script, but they do not function as they should. Any ideas? The following two files should illustrate my problem. (* filename: Development.m *) BeginPackage["Development`"] v::usage = "v[z] converts x+iy to {x, y}." hello::usage = "Says hello." Begin["Private`"] hello = Print["Hello from hello"]; v[z_] := {Re @ z, Im @ z}; End[] EndPackage[] (* filename: testPackage.nb *) SetDirectory[$UserBaseDirectory <> "/Applications"] (* returns "/Users/myusername/Library/Mathematica/Applications" *) FileNames[] (* returns {Development.m} *) << Development` hello (* returns "hello", which is a failure *) v[2 + 3 I] (* returns "v[2+3I]" which is a failure *) ?"Global`*" (* returns panel with hello and v, but no variables are listed *) Gary Palmer 2016-05-25T03:19:08Z https://community.wolfram.com/groups/-/m/t/2441773 I have a paclet and I've added the {"Documentation"} extension. I'm using the Document Tools palette to help build it. To make it easy, I've created one Reference Page (there are 300+ function in my Paclet). When running `PacletBuild` I get an error in Join: > Join::heads: Heads List and Missing at positions 1 and 2 are expected to be the same. The Call Stack shows: Join[{"Documentation/English/ReferencePages/Symbols/applyEach.nb"}, Missing["NotAvailable"], <a list of all the files in the Kernel folder>] What is PacletBuild looking for that I'm missing? ---------- Second error: After the join error, I get an error on my actual reference page: > Throw::nocatch: Uncaught Throw[Illegal manifest file: {Documentation/English/ReferencePages/Guides/Alex.nb,Documentation/English/ReferencePages/Symbols/applyEach.nb}] returned to top level. The Call Stack doesn't have any other information. Any help is appreciated. Andrew Yule 2022-01-10T16:10:31Z https://community.wolfram.com/groups/-/m/t/917616 HI -- The neural network package is really cool. I'm learning a lot from experimenting with it. I have noticed one odd thing I can't explain. I have a fairly simple CNN that I train on some images. It trains (although super-slowly) on my CPU, with a more or less reasonable loss getting smaller on each training round. But when I set TargetDevice = "GPU" it instantly reports 0 loss and finishes in just a couple seconds. As one clue, I had an Nvidia 970 with the latest Nvidia drivers and this didn't happen. I just upgraded to a new 1080 (partially for faster network training!), and that is when this started happening. I've attached a Notebook that demonstrates this behavior and has SystemInformation[] in it. (It does use images that aren't included, but I don't think there is anything special about them, they are just a bunch of JPEGs). I'm running Nvidia driver 372.70. If there is a different driver I should be using instead, please let me know. Thanks!

However, I did not succeed. Some things have been discussed previously ([here][2] and [here][3]) and I am aware that the PacletTools are still experimental but i still wanted to share my experiences. Maybe someone has a solution or a workaround or a fix. My paclet contains the main context QMRTools which loads all the sub packages. In[9]:= << QMRITools` SetDirectory[NotebookDirectory[]]; FileBaseName /@ FileNames["*.wl", "QMRITools\\kernel"] QMRITools`$Contexts Out[11]= {"CardiacTools", "CoilTools", "DenoiseTools", "DixonTools", \ "ElastixTools", "GeneralTools", "GradientTools", "ImportTools", \ "IVIMTools", "JcouplingTools", "MaskingTools", "NiftiTools", \ "PhysiologyTools", "PlottingTools", "ProcessingTools", "QMRITools", \ "ReconstructionTools", "RelaxometryTools", "SimulationTools", \ "SpectroTools", "TaggingTools", "TensorTools", "TractographyTools", \ "VisteTools"} Out[12]= {"QMRITools`GeneralTools`", "QMRITools`MaskingTools`", \ "QMRITools`NiftiTools`", "QMRITools`ElastixTools`", \ "QMRITools`PlottingTools`", "QMRITools`DixonTools`", \ "QMRITools`IVIMTools`", "QMRITools`DenoiseTools`", \ "QMRITools`CardiacTools`", "QMRITools`RelaxometryTools`", \ "QMRITools`GradientTools`", "QMRITools`TensorTools`", \ "QMRITools`JcouplingTools`", "QMRITools`SpectroTools`", \ "QMRITools`ReconstructionTools`", "QMRITools`TractographyTools`", \ "QMRITools`VisteTools`", "QMRITools`ProcessingTools`", \ "QMRITools`SimulationTools`", "QMRITools`PhysiologyTools`", \ "QMRITools`CoilTools`", "QMRITools`TaggingTools`", \ "QMRITools`ImportTools`"} In total it has over 600 functions (and options) wich all have `::usage` defined. In[13]:= functions = Sort@Flatten[Names[# <> "*"] & /@ QMRITools`$Contexts]; Length[functions] Out[14]= 647 So to build the paclet the first step is to make all the fucntion and guide pages for which i used the new DocumentaionTools palette. Notes on Documentation tools "Generate function pages": * usage text does not end in "." causes error messages during generation of the function pages. **solution**: check usage texts for closing periods. (*Check usage for end in "."*) DeleteCases[ If[StringTake[Information[#]["Usage"], -1] =!= ".", #] & /@ functions, Null] * My paclet has over 600 usage texts however it consistantly crashes between 450 and 620 notebooks. The crash is such that mathematica completely crashes, frontend and kernel. **solution**: only load half the sub contexts and generate the function pages, then load the other half of the sub contexts and generate those function pages. * If I add a single function for which I want to generate a function page I don't want to generate all 650 of them in the "Generate function pages" of the documentation palette it is possible to only generate selected pages. However this only allows for the function in the context `QMRITools'*` to be selected and not all the functions in the `QMRITools'*'*`. Also this menu automatically fills in the function found in the context. I can imaging this fails with 600+ function and options. In workbench there was the possibility to only select the missing functions. **partial solution**: it is easy to find which function pages I am missing with the following code. However it wont allow me to fill in these functions in the menu since they are not in the top level context. In[15]:= dir = "QMRITools\\Documentation\\English\\ReferencePages\\Symbols"; missing = If[! FileExistsQ[FileNameJoin[{dir, #}] <> ".nb"], #, Nothing] & /@ functions Sort[{#, Intersection[missing, Names[# <> "*"]]} & /@ QMRITools`$Contexts] Out[16]= {"ADCCalc"} Out[17]= {{"QMRITools`CardiacTools`", {}}, {"QMRITools`CoilTools`", \ {}}, {"QMRITools`DenoiseTools`", {}}, {"QMRITools`DixonTools`", {}}, \ {"QMRITools`ElastixTools`", {}}, {"QMRITools`GeneralTools`", {}}, \ {"QMRITools`GradientTools`", {}}, {"QMRITools`ImportTools`", {}}, \ {"QMRITools`IVIMTools`", {}}, {"QMRITools`JcouplingTools`", {}}, \ {"QMRITools`MaskingTools`", {}}, {"QMRITools`NiftiTools`", {}}, \ {"QMRITools`PhysiologyTools`", {}}, {"QMRITools`PlottingTools`", {}}, \ {"QMRITools`ProcessingTools`", {}}, \ {"QMRITools`ReconstructionTools`", {}}, \ {"QMRITools`RelaxometryTools`", {}}, {"QMRITools`SimulationTools`", \ {}}, {"QMRITools`SpectroTools`", {}}, {"QMRITools`TaggingTools`", \ {}}, {"QMRITools`TensorTools`", {"ADCCalc"}}, \ {"QMRITools`TractographyTools`", {}}, {"QMRITools`VisteTools`", {}}} ![enter image description here][4] ![enter image description here][5] With some workarounds I eventually managed to generate all the function pages such that I can build my paclet using the `PacletTools`. However here things get messy and I am not able to build my packlet. PacletTools: * PacletDocumentationBuild[] also consistently crashes between 400 and 500 function pages build. * PacletDocumentationBuild[ , , "HTML"] also consistently crashes Mathematica between 400 and 500 function pages build. * PacletBuild needs to always rebuild the full documentation. If I have done full documentation build already and only change some function definitions or Asset but no function or guide pages I still have to rebuild the entire documentation. **solution**: "manually" copy the changed notebooks or Asset to the build directory and use CreatePacletArchive to pack the Build directory to a packet file. The code below copies all *.wl files and the paclet Extentions to the build folder. This way i can only call `PacletDocumentationBuild` when I think it is needed. Options[ApplicationBuild] = {RebuildDoc -> False, RebuildHTMLDoc -> False, MakeArchives -> True}; ApplicationBuild[location_?StringQ, opts : OptionsPattern[]] := ApplicationBuild[LoadApplicationFolder[location], opts] ApplicationBuild[pac_, OptionsPattern[]] := Block[{location, name, filesApp, filesAppTar, buildDir}, location = pac["Location"]; name = pac["Name"]; buildDir = FileNameJoin[{location, "build", name}]; Print["Building " <> name <> " in location " <> location]; Print[" - Building application"]; filesApp = Prepend[ Flatten[ Select[Normal[ PacletExtensionFiles[pac]], #[[1, 1]] =!= "Documentation" &][[ All, 2]]], FileNameJoin[{location, "PacletInfo.wl"}] ]; filesAppTar = StringReplace[#, location -> buildDir] & /@ filesApp; MapThread[( Quiet@CreateDirectory[DirectoryName[#2]]; CopyFile[#1, #2, OverwriteTarget -> True] ) &, {filesApp, filesAppTar}]; If[OptionValue[RebuildDoc], Print[" - Rebuilding documentation"]; PacletDocumentationBuild[pac, DirectoryName[buildDir]] , Print[" - Not building documentation"]; ]; If[OptionValue[RebuildHTMLDoc], Print[" - Rebuilding html documentation"]; PacletDocumentationBuild[pac, buildDir <> "-html", "HTML"] , Print[" - Not building html documentation"]; ]; If[OptionValue[MakeArchives], Print[" - Making paclet and archive"]; CreatePacletArchive[buildDir]; CreateArchive[buildDir, FileNameJoin[ Append[Drop[FileNameSplit[buildDir], -1], name <> "-" <> pac["Version"] <> ".zip"]], OverwriteTarget -> True]; , Print[" - Not making paclet and archive"]; ]] So in the end I can manage everything to work all the way I want. However, I cannot finish the documentation (and HTML) builds since the Mathematica FrontEnd crashes after processing ~400 files. ![enter image description here][6] [1]: https://community.wolfram.com/groups/-/m/t/1661539 [2]: https://community.wolfram.com/groups/-/m/t/2436487 [3]: https://community.wolfram.com/groups/-/m/t/2427576 [4]: https://community.wolfram.com//c/portal/getImageAttachment?filename=selected.png&userId=1332602 [5]: https://community.wolfram.com//c/portal/getImageAttachment?filename=selected-notallowed.png&userId=1332602 [6]: https://community.wolfram.com//c/portal/getImageAttachment?filename=crash.png&userId=1332602 [7]: https://community.wolfram.com//c/portal/getImageAttachment?filename=debug.png&userId=1332602 Martijn Froeling 2022-01-26T11:50:33Z https://community.wolfram.com/groups/-/m/t/1669257 I installed gcc but Mathematica (12) cannot seem to find it.

To be honest, I am disappointed with Wolfram QuantumFramework as it looks similar to qiskit/Q#. If you want to compare, download the Quantum package by Gómez-Muñoz & Delgado (it runs under Mathematica 13). Here are some notebooks (and pdf's of the notebooks if you do not want to download the Quantum Package) and check out the application examples eg Quantum Teleportation. http://homepage.cem.itesm.mx/lgomez/quantum/menucomputing.html I thought the Wolfram QuantumFramework would be more similar to the Quantum Package, but I was disappointed to see its more like Qiskit . Doug Beveridge 2021-12-21T17:51:52Z https://community.wolfram.com/groups/-/m/t/909511 How do I run pre-Mathematica 11 Notebooks in Mathematica 11? Hi I just upgraded. I have Mathematica notebooks made I like to use in a previous version. The first I tried uses Sphere[]. But it's broken and there's no "import". Instead of renaming some NEW function that doesn't do the same thing, Mathematica clobbers Sphere with a new definition. I found there is a trail of "legacy .m" files one can download one at a time (GUGH!) such as "WorldNames.m". However Sphere is "built-in" and I'm unsure if any "legacy.m" will prevent me from re-writing all my packages. I refuse to see why 11 has to clobber my notebooks. And I'm wondering right now if new employees Wolfram at expect that my notebooks are SACRIFICIAL, and that only their new release easiness matters ? Put another way, if i can't make mm10 run in 11, will mm11 notebooks run in 12? why am i urged to upgrade instead of keeping one of every version if they have taken a policy of creating version incompatibility? What is the point of making notebooks if their functionality cannot be shared with others and are clobbered in any given mathematica release? Their's always work and are sold mine are always broken and i'm up the creek? Who's paying again? I'm a huge Mathematica fan despite this issue but it's an issue I will Raise Anonymous User 2016-08-19T19:04:39Z https://community.wolfram.com/groups/-/m/t/816033 LibraryLink backwards *and forwards* compatibility seems to have been broken in version 10.4.0. Was this intentional or is it a bug? I am seeing the problems on OS X, and I *think* they don't exist on Windows (per reports of others): * If I compile my library with 10.3, it crashes in 10.4. * If I compile it with 10.4, it doesn't load in any of the previous versions (10.0–10.3). 10.0–10.3 were both backwards and forwards compatible with each other. Is this a bug or is it expected (intentional)? If it is intentional, that is very bad news because it makes it prohibitively complicated to create add-ons that use LibraryLink. I would have to compile my library *separately for each Mathematica version* on each operating system (not to mention adding code for selecting the right library to load for each version). It is already a big burden to compile on each operating system. If I also have to compile for each version, then I will be forced to simply give up. Only a company can devote so much resource to support a Mathematica add-on, and everyone else (i.e. people using a university site license) will be cut off. If it is a bug, that is a very good argument for bringing back the prerelease programme. If it is a bug, can we expect a 10.4.1 to fix this? I have a published package ([IGraphM](http://community.wolfram.com/groups/-/m/t/560469)) that is directly affected by this problem.

IMO, the .nb file is more straightforward to learn, study, and develop. So, I want to know if I can import a .wl file into .nb format to help understand and study it. Regards, HZ Hongyi Zhao 2022-02-25T14:38:25Z https://community.wolfram.com/groups/-/m/t/403833 I have read through the documentation and watched the videos. I even poked around to find older material. I think I understand how to set up a package in Workbench. However, all the examples I have seen have a single .m file for the code. I want to make a package/application that has multiple source files. How do I do this? Does each .m file have to have its own BeginPackage[]/EndPackage[] context, or can there be just one .m file that sets the context and the other source files are included as optional arguments to the only BeginPackage[] function call? In the past, packages have been set up with a 'master' package that was called (Get[] or Needs[]) that would load all the sub-packages -- each of those could the loaded individually. How would I go about setting this up? Thanks. George Woodrow III 2014-12-08T13:59:33Z https://community.wolfram.com/groups/-/m/t/1400212 Dear Wolfram team: I am a beginner of Mathematica. My Problem is that I want solve a System with n equation of Motion in first order. In this equation of motion are creation and annihilation operators of Dirac-fermions. **I don't know and don't find a it, how I can describes the creation and annihilation operators of Dirac-fermions in Mathematica**. The equation of motion have the form: $$\dot{c}_i^\dagger [t]=f*c_i^\dagger[t]+g[t]*c_{i+1}[t]-g[t]*c_{i+1}^\dagger[t]+h[t]*c_{i-1}[t]-h[t]*c_{i+1}^\dagger[t]\\ \dot{c}_i [t]=f*c_i[t]+g[t]*c_{i+1}^\dagger[t]-g[t]*c_{i+1}[t]-h[t]*c_{i-1}^\dagger[t]+h[t]*c_{i+1}[t],$$ where $c_i^\dagger,c_i $ are creation and annihilation operators and f,g,h are functions. Then I want use DSolve or NDSolve to solve the equation of motion. Thanks, for your help. C.
