fastText -autotune-validation not working

问题

I am trying to use the autotune-validation command to check the f1 score of a dataset I am working in.

I tested fastText in two different machines (Ubuntu and MAC), but I got the following error:

Unknown argument: -autotune-validation

The following arguments are mandatory:
  -input              training file path
  -output             output file path

The following arguments are optional:
  -verbose            verbosity level [2]

...

I tried to read the documentation, but according to the fastText website, this command should work fine.

./fasttext supervised -input commits.train -output commits -autotune-validation commits.valid

I expected the -autotune-validation command to work fine as described here
