"""
This is a test script to compare the loaders and models.
This script creates one identical splits for the openfield test dataset and trains it with imgaug (default), scalecrop
and the tensorpack loader. We also compare 3 backbones (mobilenet, resnet, efficientnet)
My results were (Run with DLC *2.2.0.4* in Jan 6 2022) for 50 k iterations
DLC_mobnet_35_openfieldOct30shuffle0_50000 and Imgaug with # of training iterations: 50000
Results for 50000 training iterations: 95 0 train error: 3.06 pixels. Test error: 3.44 pixels.
With pcutoff of 0.4 train error: 3.06 pixels. Test error: 3.44 pixel
DLC_mobnet_35_openfieldOct30shuffle1_50000 and scalecrop with # of training iterations: 50000
Results for 50000 training iterations: 95 1 train error: 2.44 pixels. Test error: 3.84 pixels.

Results for 50000 training iterations: 95 2 train error: 2.41 pixels. Test error: 3.04 pixels.
With pcutoff of 0.4 train error: 2.41 pixels. Test error: 3.04 pixels
DLC_resnet50_openfieldOct30shuffle3_50000 and Imgaug with # of training iterations: 50000

Results for 50000 training iterations: 95 4 train error: 2.0 pixels. Test error: 2.69 pixels.
With pcutoff of 0.4 train error: 2.0 pixels. Test error: 2.69 pixels
DLC_resnet50_openfieldOct30shuffle5_50000 and tensorpack with # of training iterations: 50000
Results for 50000 training iterations: 95 5 train error: 1.96 pixels. Test error: 2.65 pixels.
With pcutoff of 0.4 train error: 1.96 pixels. Test error: 2.65 pixels
DLC_effnet_b3_openfieldOct30shuffle6_50000 with Imgaug with # of training iterations: 50000
Results for 50000 training iterations: 95 6 train error: 2.63 pixels. Test error: 2.65 pixels.
With pcutoff of 0.4 train error: 2.63 pixels. Test error: 2.65 pixels
effnet with tensorpack and scalecrop didn't converge.
Notice: despite the higher RMSE for imgaug due to the augmentation,
the network performs much better on the testvideo (see Neuron Primer: https://www.cell.com/neuron/pdf/S0896-6273(20)30717-0.pdf)
