I use MMA 11.3 and obtain the strange behavior of the DumpSave/Get routines. I've saved the results of long computations using 

SetDirectory[dir];
DumpSave["file.mx", {res, k, fn}];

I've checked that all variables contain actual data before saving. Files were created at every mentioned folder and all of them have different size. However, later using the Get["file.mx"], I see the non-assigned variables res, k and fn. Moreover, the

Names["Global`*"]

returns me an empty list (just some built-in variables) after evaluation of the Get["file.mx"].

Do anybody know how to take the data from mx-files? One of the problematic files is here (~2Mb)

  • $\begingroup$ I think for anyone else to better investigate this, we'll need some information on what's behind those actual values. Because with a simple example it just works. $\endgroup$

  • $\begingroup$ In my case, the res is a table with some dozens of thousands of elements, where each element is like {num,num}. But it should work for any data inside expression. I've used this earlier with older versions of MMA without any problems. $\endgroup$

  • $\begingroup$ No doubt it should work. But if no one can reproduce it it is unlikely they'll be able to help. Can you provide a simple command that mimics the dimensions and type of your data (some sort of Table) that you seem able to reproduce the issue with, without needing your full code? $\endgroup$

  • $\begingroup$ The exact data structure of res is like following: Table[Transpose@N@Table[{i/7, i/3}^(3/k), {i, 1, 300}], {k, 1, 44}], the fn is a list of 44 filenames and k is a simple number. $\endgroup$
