packages - How to remove a paclet downloaded from Wolfram Research Server?


How can I remove a paclet that was automatically downloaded when I used a function for the first time (i.e. NetChain)?


I believe the download was faulty, preventing me from using any of the functions from that paclet (e.g. ElementwiseLayer, etc.). That's why I want to redownload it. If I understand correctly, paclets are downloaded from the Wolfram Research Server when an uncommon function such as NetChain or Sound are used for the first time (indicated by a blue progress bar under the cell).




Answer



Use PacletFind to find the installed versions, of the paclet, for exmaple:


paclets = PacletFind["*MX*"]
(*{Paclet[MXNetLink,11.1.0,<>]}*)

Then evaluated PacletUninstall to remove said paclet. For example


PacletUninstall[ paclets[[1]] ]

I recommend using Part to select the paclet. If you copy/paste, you'll need to be careful to select the visible expression along with its interpretation. It's a little to easy to select just the displayed Paclet["foo",<>] without the interpretation.


If you like to see where the paclets are installed, use the following and again, be careful about directly copying the outputs:



Table[{paclet, "Location" /. PacletInformation[paclet]}, {paclet, 
   paclets}] // TableForm

functions - Get leading series expansion term?

Given a function f[x] , I would like to have a function leadingSeries that returns just the leading term in the series around x=0 . For example: leadingSeries[(1/x + 2)/(4 + 1/x^2 + x)] x and leadingSeries[(1/x + 2 + (1 - 1/x^3)/4)/(4 + x)] -(1/(16 x^3)) Is there such a function in Mathematica? Or maybe one can implement it efficiently? EDIT I finally went with the following implementation, based on Carl Woll 's answer: lds[ex_,x_]:=( (ex/.x->(x+O[x]^2))/.SeriesData[U_,Z_,L_List,Mi_,Ma_,De_]:>SeriesData[U,Z,{L[[1]]},Mi,Mi+1,De]//Quiet//Normal) The advantage is, that this one also properly works with functions whose leading term is a constant: lds[Exp[x],x] 1 Answer Update 1 Updated to eliminate SeriesData and to not return additional terms Perhaps you could use: leadingSeries[expr_, x_] := Normal[expr /. x->(x+O[x]^2) /. a_List :> Take[a, 1]] Then for your examples: leadingSeries[(1/x + 2)/(4 + 1/x^2 + x), x] leadingSeries[Exp[x], x] leadingSeries[(1/x + 2 + (1 - 1/x...

How to thread a list

front end - keyboard shortcut to invoke Insert new matrix

I frequently need to type in some matrices, and the menu command Insert > Table/Matrix > New... allows matrices with lines drawn between columns and rows, which is very helpful. I would like to make a keyboard shortcut for it, but cannot find the relevant frontend token command (4209405) for it. Since the FullForm[] and InputForm[] of matrices with lines drawn between rows and columns is the same as those without lines, it's hard to do this via 3rd party system-wide text expanders (e.g. autohotkey or atext on mac). How does one assign a keyboard shortcut for the menu item Insert > Table/Matrix > New... , preferably using only mathematica? Thanks! Answer In the MenuSetup.tr (for linux located in the $InstallationDirectory/SystemFiles/FrontEnd/TextResources/X/ directory), I changed the line MenuItem["&New...", "CreateGridBoxDialog"] to read MenuItem["&New...", "CreateGridBoxDialog", MenuKey["m", Modifiers-...
