"An internal error occurred" What does that mean?

  • 1.  "An internal error occurred" What does that mean?

    Hi everyone,

    I use the syntax for a violin plot and everything looks good. When I run the graph syntax however, it looks like it's creating the graph but then it stops and a message in red appears in the middle of the space where the graph should pop up:
    Since it does not look like an error from the syntax itself, I am wondering what could be the source of it. 

    I am using version 26, my dataset contain 368,000ish entries (census).

    Any thoughts?

    Thank you so much!

    An internal error is something like running out of memory or an unusual condition not being handed properly by the code.  I suspect a memory problem here.  try taking, say, a 10% random sample of the data and plotting that to see what happens.  then 25% etc.  The code subsystem handling this plot probably has to hold all the data in memory.

    Thanks Jon for your insights.

    I actually created another dataset of 5% sample and I still get the same internal error message.

    I have a iMac: Processor: 2,3 GHz Intel Core i5, Memory: 8 Go 2133 MHz DDR4

    Maybe it is not enough ? I did not know violin plot was so highly demanding in terms of memory.

    First, how are you doing this plot?  Violin plot is not a built-in chart type, but there is a template around that adds it.  But maybe  you are doing this some other way.

    Second, if you want to send me the 5% sample data and the syntax and, if you can, the violin plot template as I don't have that on  my current machine, I can try to reproduce this.

    Typically this means the generated chart is in error.  The GPL may be correct, but somehow the data is in conflict.  For example, if you have a list of nodes and links, but you try to connect links to non existent nodes.

    If you open a command prompt and change to the MacOS directory (

    /Applications/IBM/SPSS/Statistics/26/SPSSStatistics.app/Contents/MacOS on my system), and run "./stats", and re-execute your syntax, likely a bunch of technical internal errors will print to the console.  It might give you a clue as to what the issue is.  If not, post it here and I'll take a look.
