the limbs are not visible after training the model

[r11alaa]

hello @last-one ,
please I need some help
I have trained the openpose using this code but when I tried to test the trained model I had the key points of the human body but not the limb connections.

1- I have used this because some loading errors:
model = pose_estimation.PoseModel(num_point=19, num_vector=19)
state_dict = torch.load(args.model)['state_dict']
from collections import OrderedDict
new_state_dict = OrderedDict()
for k, v in state_dict.items():
name = k[7:]
new_state_dict[name] = v
state_dict = model.state_dict()
state_dict.update(new_state_dict)
model.load_state_dict(state_dict)
model = model.cuda()
model.eval()
2- for the limb sequence I have used this code
limbSeq = [[3,4], [4,5], [6,7], [7,8], [9,10], [10,11], [12,13], [13,14], [1,2], [2,9], [2,12], [2,3], [2,6],
[3,17],[6,18],[1,16],[1,15],[16,18],[15,17]]

mapIdx = [[19,20],[21,22],[23,24],[25,26],[27,28],[29,30],[31,32],[33,34],[35,36],[37,38],[39,40],
[41,42],[43,44],[45,46],[47,48],[49,50],[51,52],[53,54],[55,56]]
3- in the for loop over the parts:
for part in range(1,19):

the resulting image:

please If any one can help
