Error when increasing batch size

[herybala]

I saw we get error when increasing batch size in dataloader

Hi Herybala,

Yes, in the code, we assume the batch size to be 1 (which means we train with 1 frame at a time). However, you can increase the number of pixels you want to sample like in here (4 32 32 = 4K by default)

Sorry wrong manipulation, i found the problem Hello, Also when setting sampler to edge i got the following error:

hydra.errors.ConfigCompositionException: Could not override 'sampler.dilate'. To append to your config use +sampler.dilate=8

Hi Herybala,

From the error it appears that you are trying to pass parameters that EdgeSampler doesn't recognise to it (dilate in this case). If you want to switch sampler you can either:

1. change "patch" to "edge" here
2. or specify in the command line like "python train.py sampler=edge"
