rename model_id

[farhad...@gmail.com]

Is there any way from any of the APIs ( preferably R, but any api is OK ) to change the model unique id ? 

I have bunch of models stored in different folders, unfortunately with same model key. When I import them they override each other. ideally I am looking for something like which is not working:

model  = h2o.getModel("model1");

attr(model, "model_id" ) = "model2"; 

h2o.saveModel(model2, "...");

+1 for this feature. I'd like to see this too.

model.model_id = "asieurta8w4a"

Spencer,
Is there an R / Flow equivalent of renaming a model?

oh nope doesn't look like it -- i thought h2o assign did this for R.

let's addit!

Was this ever added? Would be fantastic to have this ability in R.

I realise you could specify it on the fly when building a single model, but that option isn't available during a grid search as far as I can see. Manually changing the name of any/all of the model_id slots in the model also doesn't work. When you try and save the model again (in this case with model_id set to "test"), you get the following error:

Object 'test' not found for argument: model_id

Further request for confirmation this feature was added. I haven't been able to find it in the documentation anywhere.

[james.m...@gmail.com]

I checked to see if it could be changed simply by assigning a different value for model_id using "my_model@model_id <- "new_name"" and while that changed the model_id associated with the object in R, when I tried to save the model it threw an error for failing to locate a model with the new assigned name.

I’d be happy to just have the support to rename frames and models in Flow.

So much of the meta data about our frames (which comes from CSV files) are embedded in the name itself. Same with the model name, so having the ability to change would be nice.

Scott,

I remember that you asked me about this a while ago... did you create a
JIRA ticket for this? If not, please do! I think it would be useful to
be able to rename frames and models in Flow.

I did and I will!

Also found a potential bug in GBM, hopefully reproducible on your end. We found a case, where after around 1000 trees chugging along at 5 seconds per tree, suddenly switches to 0.5 seconds per tree. Weird. I have a screenshot for you. Will send tomorrow.
