TypeError: object of type 'numpy.float32' has no len()

Line 177 has a type error. The example in your 19 year video ran smoothly, but I trained a new one to encounter this error.

May I ask if there is a problem with my training set or with the version? Please help

Which model are you using? I've seen that error before when trying to train a different model than ssd-mobilenet-v2.

It is indeed a version issue, and I have solved the problem using your code from last year's version of TF. Thank you very much!

Hello everyone. I used the ssd-mobilnet-v2 version, teaching her on this collab notebook https://colab.research.google.com/github/EdjeElectronics/TensorFlow-Lite-Object-Detection-on-Android-and-Raspberry-Pi/blob/master/Train_TFLite2_Object_Detction_Model.ipynb?authuser=2#scrollTo=6t8CMarqBqP9 and I got the same error as you. Can you tell me how to fix it?
