Why the reconstructed image is very blurry color_000

I execute according to the readme command, and the data set uses the data downloaded in mip Nerf360

How long did you train for?

How long did you train for?

250000 iterations，Use the configuration of 360.gin，Config.batch_size=16

The batch size needs to be way bigger.

Hi, @jonbarron . I'm now using blender_refnerf.gin, but due to memory limitations, the batch_size is set to 2048, how many rounds of training would be better? Is 500,000 rounds enough?

I'd follow the "linear scaling rule" when changing batch size. You should be scaling up the number of iterations and scaling down the learning rate so that the model sees the same number of pixels as it had previously.
