Training on a different dataset #12

Closed ArmandZampieri closed 6 years ago

ArmandZampieri commented 6 years ago

Hi anuragranj,

I'm trying to use spynet on a personal dataset, but I'm having issues concerning the training part, I converted my data to the ppm and flo format and renamed them to match the structure of the flying chair dataset, but when runnning

th main.lua -fineWidth 128 -fineHeight 96 -level 3 -netType volcon \ -cache checkpoint -data myDir \ -L1 models/modelL1_3.t7 -L2 models/modelL2_3.t7 \ -retrain models/modelL2_3.t7

it fails trying to locate a file not in the dataset:

~/spyNetTrainImages/00666_img1.ppm: No such file or directory

I would like to know if you could give me advice on how to train spynet on a different dataset

Thank you for your attention, Best regards.

Can you paste your data directory structure here? You also need to have a train_val_split.txt file which flags train and validation splits. Your error seems like the files might not be located in the data directory.

Thank you for your answer,

The data directory contains all the data in one folder named like this:

imageName1_img1.ppm imageName1_img2.ppm imageName1_flow.flo imageName2_img1.ppm imageName2_img2.ppm ...

I have the initial train_val_split.txt file containing 1 and 2

The data loading happens in donkey.lua. You need to make sure that these paths exist: https://github.com/anuragranj/spynet/blob/master/donkey.lua#L297-L298
