about the parameter in nanodet-plus-m-1,5x-416

[Kilig0215]

the train method has shown the parameter like this
LOCAL_RANK: 0 - CUDA_VISIBLE_DEVICES: [0]

| Name | Type | Params

0 | model | NanoDetPlus | 7.7 M
1 | avg_model | NanoDetPlus | 7.7 M

15.5 M Trainable params
0 Non-trainable params
15.5 M Total params
61.915 Total estimated model params size (MB)
but what I saw in readme
the parameter is 2.44M, is there any wrong between them?
