Missing DatasetLoader in api.lua

[eugene8568]

Hi Mr. Farrajota,

I tried to run train the fastrcnn model using your dbcollection torch but stuck at step 5 when it tried to load dataset.

~/Documents/fastrcnn-example-torch$ th train.lua -dataset coco -netType vgg  
==> (1/5) Load options  
==> (2/5) Load dataset data loader                                                                              `
==> (3/5) Load roi proposals data
==> (4/5) Setup model:
==> (5/5) Train Fast-RCNN model

Any advice? Thanks
