Trouble getting things running

[Zank Bennett]

Hi,

I'm using a mac, and have installed mono (it works fine for the "Hello world" demo).

I downloaded MyMediaLite 3.1.1 and changed to the lib/ directory.

From there I use:

mono rating_prediction.exe --training-file="../../data/demo.txt" --test-file="../../data/demo.txt" --recommender=UserAverage

Any ideas why I receive this error?

Here's the input file:

cat ../../data/demo.txt

  1       1       5
  1       2       3
  1       3       4
  1       4       3
  1       5       3
  1       7       4

I tried absolute file paths. Same error.

Thanks

I got it figured out.

1. I needed to use absolute paths (I thought I had done that) and

2. My input file (copied from on of the examples) has an invalid format

I hope this helps someone else :)
