How to use

import torch
from cjm_yolox_pytorch.model import MODEL_TYPES, build_model

Select model type

model_type = MODEL_TYPES[0]
model_type

'yolox_tiny'

Build YOLOX model

yolox = build_model(model_type, 19, pretrained=True)

test_inp = torch.randn(1, 3, 256, 256)

with torch.no_grad():
    cls_scores, bbox_preds, objectness = yolox(test_inp)
    
print(f"cls_scores: {[cls_score.shape for cls_score in cls_scores]}")
print(f"bbox_preds: {[bbox_pred.shape for bbox_pred in bbox_preds]}")
print(f"objectness: {[objectness.shape for objectness in objectness]}")
