index page: data link points to wrong page?
On this page Welcome to fastai – fastai, all the data links point to vision.data, but according to the context, they should point to links of basic_data. Do I understand the context correctly? Could anyone double check them for me? thanks!
Then, there are three modules directly on top of
torch_core:
data, which contains the class that will take aDatasetor pytorchDataLoaderto wrap it in aDeviceDataLoader(a class that sits on top of aDataLoaderand is in charge of putting the data on the right device as well as applying transforms such as normalization) and regroup then in aDataBunch.
This takes care of the basics, then we regroup a model with some data in a
Learnerobject to take care of training. More specifically:
callback(depends ondata) defines the basis of callbacks and theCallbackHandler. Those are functions that will be called every step of the way of the training loop and can allow us to customize what is happening there;
From
datawe can split on one of the four main applications , which each has their own module:vision,textcollab, ortabular. Each of those submodules is built in the same way with:
