What are the model parameters and MACs ?

[jackydinosaur]

Hello, thanks for great work!
I run the code from [OSTrack/tracking/profile_model.py] to measure the model parameters and MACs .(https://github.com/botaoye/OSTrack)
Howerer, overall params is 739.205K, which is different from 3.8M in the paper.
The experiments.yaml and lib/config/* are the same as Main branch(8b99155).
Could you please tell me how to measure the model size?

Hi,

Thank you for your interest in our work. OStrack's model profiler uses the thop package to measure the number of model parameters and MAC operations. However, the thop package generates erroneous results in some cases.

I have now added a script, which iterates over the state dictionary of the model and computes the number of parameters. I haven't found a similar approach for MAC operations yet. Feel free to create a PR if you find a relevant solution.
