Hi, I'm slightly confused about tensorboard charts. The model I trained:

models = [NHITS(h=horizon,

input_size=6*horizon,

loss=MSE(),

valid_loss=MSE(),

exclude_insample_y=False,

max_steps=100000,

val_check_steps=10,

batch_size=32,

valid_batch_size=32,

n_freq_downsample=[8, 4, 2, 1, 1],

n_blocks=5*[1],

mlp_units=5 * [[64, 64]],

dropout_prob_theta=0.2,

hist_exog_list=hist_exog_list,

learning_rate=1e-4,

step_size=step_size,

scaler_type='identity'

)
