Is it possible to check h2o version of the model saved in file?

I would like to check h2o version assigned to a model saved in file. Is it possible in current h2o editions (I have eg. 3.29.0.4930)?

I can't find it in the messages written during h2o.loadModel() in R console unless there is a mismatch in h2o versions: "Error in .h2o.doSafeREST(h2oRestApiVersion = h2oRestApiVersion, urlSuffix = page, : ERROR MESSAGE: Found version 3.14.0.3, but running version 3.29.0.4930"

Can I access it before loading model using h2o?

Solution

  • If you open the binary model file with a text editor, you will see that the first line would display the H2O version it was saved in.

    For example, using unix based command head -n 1 your_model_file returns

    ?   3.32.0.3 ...
