Thank you for your outstanding work. I encountered some problems during my study and would like to ask you for advice.

your is right, split and saved is wrong

model_fold is download. pred is right

model = tf.saved_model.load(os.path.join(model_fold, "metrabs_rn18_y4"))
pred = model.estimate_poses(np.array(frames), boxes=np.array([[0,0,255,255]], dtype=np.float32))

wrong one, preds is img above. model_folder is I first split the crop model into two models: backbone and head. and saved

model_bbone_folder = r"----------\resnet18\bbone"
model_bbone = tf.saved_model.load(model_bbone_folder)

model_head_folder = r"---------------\resnet18\metrab_head"
model_head = tf.saved_model.load(model_head_folder)
feat = model_bbone(frames)
feat = feat.numpy()

feat = feat.astype(np.float16)
pred = model_head(feat, False)

1. split the crop model into two models: backbone and head.

2. save them into two models respectively.

3. two split models, load the overall model you provided, and verify it.

all the abs is 0.0
model_bbone_folder = r"-------------\resnet18\bbone"
model_bbone = tf.saved_model.load(model_bbone_folder)
for i in range(len(model_backbone_vars)):
     string = model_backbone_vars[i].name + "-" + model_make.variables[i].name
     abs =  model_backbone_vars[i].numpy()-model_bbone.variables[i].numpy()
     abs = np.max(abs)
     print(string, abs)

4. loaded separately and inferred.
