Arguments

dls

It is a DataLoaders object.

layers

layers

emb_szs

emb_szs

config

config

n_out

n_out

y_range

y_range

loss_func

It can be any loss function you like.

opt_func

It will be used to create an optimizer when Learner.fit is called.

lr

It is learning rate.

splitter

It is a function that takes self.model and returns a list of parameter groups (or just one parameter group if there are no different parameter groups)

cbs

It is one or a list of Callbacks to pass to the Learner.

metrics

It is an optional list of metrics, that can be either functions or Metrics.

path

İt is used to save and/or load models.Often path will be inferred from dls, but you can override it or pass a Path object to model_dir. Make sure you can write in path/model_dir!

model_dir

İt is used to save and/or load models.Often path will be inferred from dls, but you can override it or pass a Path object to model_dir. Make sure you can write in path/model_dir!

wd

It is the default weight decay used when training the model.

wd_bn_bias

It controls if weight decay is applied to BatchNorm layers and bias.

train_bn

It controls if BatchNorm layers are trained even when they are supposed to be frozen according to the splitter.

moms

The default momentums used in Learner.fit_one_cycle.

Value

learner object
