Saving and loading H2O Model POJO from python

[Jithin K M]

Could anybody tell me how to save and load H2O Model POJO from Python?

Thanks.

Hi,

The following link has an example building a model and downloading its POJO from Python: http://h2o-release.s3.amazonaws.com/h2o/rel-tibshirani/8/docs-website/h2o-docs/index.html#POJO%20Quick%20Start-Extracting%20Models%20from%20H2O

Thanks,

Hi Avni,

Thanks for your help.

I gone through that doc. But after downloading POJO using 'h2o.download_pojo(model)', how can I use the downloaded POJO? I couldn't find the downloaded POJO anywhere in my system. Also if I have a downloaded POJO, how can I load it again to predict my test inputs?

Thanks

Jithin

Hi Jithin,
Are you aware of the differences in using a POJO model vs a binary format model for making predictions?

If you aren't putting this model in production right away, it's easier to use the `h2o.saveModel` and `h2o.loadModel` functions (in the R package).  If you are looking to go to production, visit our POJO docs: http://h2o-release.s3.amazonaws.com/h2o/rel-tibshirani/8/docs-website/h2o-docs/index.html#POJO%20Quick%20Start-Use%20Cases

Best,
Erin

Oops, I just saw that you are using Python, not R.  In that case, check out the `h2o.save_model` and `h2o.load_model` functions.

Thanks Erin. I will try the method you specified.

Thanks Erin.

h2o.save_model and  h2o.load_model works fine for me.
