demo_segmentation.py output being black

[Lance4Liu]

I train the models using train_segmentation.py, with train_config.yml being:

output_root: '../'
pytorch_data_dir: '../'
experiment_name: "exp3"
log_dir: "cocostuff27"
azureml_logging: True
submitting_to_aml: False

# Loader params
num_workers: 0
max_steps: 5000
batch_size: 16

num_neighbors: 7
dataset_name: "directory"

# Used if dataset_name is directory
dir_dataset_name: "dataset_brain"
dir_dataset_n_classes: 3


has_labels: False
crop_type: None
crop_ratio: .5

# Model Params
extra_clusters: 0
use_true_labels: False
use_recalibrator: False
model_type: "vit_small"
arch: "dino"
use_fit_model: False
dino_feat_type: "feat"
projection_type: "nonlinear"
#projection_type: linear
dino_patch_size: 8
granularity: 1
continuous: True
dim: 70
dropout: True
zero_clamp: True

lr: 5e-4
pretrained_weights: ~
use_salience: False
stabalize: False

# Feature Contrastive params

neg_inter_weight: 0.63
pos_inter_weight: 0.25
pos_intra_weight: 0.67

hydra:
  run:
    dir: "."
  output_subdir: ~
  #job_logging: "disabled"
  #hydra_logging: "disabled"

Then I run the demo_segmentation.py with demo_config.yml being:

output_root: '../'
model_path: "../checkpoints/cocostuff27/directory_exp3_date_Jan18_23-39-07/epoch=57-step=799.ckpt"
image_dir: "../test_brain"
experiment_name: "exp3"
res: 320
batch_size: 8
num_workers: 0
use_ddp: False

hydra:
  run:
    dir: "."
  output_subdir: ~
  #job_logging: "disabled"
  #hydra_logging: "disabled"

But the output in results\predictions\cluster is totally dark.
Can someone tell me what should I do for this? More epoches? Or some paths in the configs should be edited?
I train the epoch for about 50.
