Thanks for sharing your code! I'm trying to test your code. But I met an error like:

(mathnas3.9) mac@MacBookAir MathNAS % python main.py --mode nas --search_space mobilenetv3 --device raspberrypi --latency_constraint 500
==> save path is [results/mobilenetv3/raspberrypi] ...
=====> search space is [mobilenetv3] ...

Do I need to sign in gurobi and get a license?

Yes, in order to use Gurobi on edge devices, you need to get a license. Specifically, I applied as a student at http://www.gurobi.cn/NewsView1.Asp?id=4. After filling out the application form, the approval process is available within a few days. (I got it the next day)

@wangqinsi1 OK! I'll try it. Thanks for your kind answer.
