For Windows I just learned that you can get the "SemanticImport::unexpinvaliderr: Unexpected invalid input was detected. Processing will not continue" message, if the name of your "TemporaryDirectory" contains a space. So you can solve it by setting $TemporaryDirectory to an other existing(!) directory (or create it first) without a space in the name. Example:

CreateDirectory["C:\temp"]

$TemporaryDirectory = "C:\temp"

This is propably the reason why SemanticImport, works for some and not for others. I don't know if the same is true for Mac OS.

Hello everyone

I have just started using Mathematica and am running into a bit of the same as described here problem. When using SemanticImport, I always get the same error:

"SemanticImport::unexpinvaliderr: Unexpected invalid input was detected. Processing will not continue"

I tried putting my file in different paths as well, seeing as sometimes the symbols in my paths are messing with some programs. I tried paths with the user in it, without the user, putting it straight into my "C:" directory, having it in my Mathematica folder etc. Nothing has worked so far. In the link that I posted, it said that using the following method would temporarily fix the problem

Block[{$TemporaryDirectory = "C:\\temp"}, SemanticImport["ExampleData/RetailSales.tsv"]]

but that just gives me the following error:

"SemanticImport::temperr: $TemporaryDirectory is not an existing directory."

Does anyone have a workaround for this problem / knows what I could do to fix it?

Thanks
