I finally found out that ,this is due to encoding, I encode the input file in ascii format, then it begin to run

Hi,

I get the same error as you did, but my file is already encoded in us-ascii. Do you know how to correct it?

Thanks!

I am also getting the same error cannot parse line " 0:1 1:1" at character. Any idea how to resolve it ?

Please always try to give the command line you are using and also a sample of your training file to see where the problem is.

In your example, The format is always something like "0 0:1 1:1" you are missing the target in your line (First number)

If you run libFM in windows, please ensure use '\n' to start a new line.
