from tensorflow.keras.models import model_from_json json_file = open('keras-facenet-h5/model.json', 'r') loaded_model_json = json_file.read() json_file.close() model = model_from_json(loaded_model_json) # XXX model.load_weights('keras-facenet-h5/model.h5') Error: TypeError: Could not locate class…

In addition, the syntax used is not pythonic. This is the recommended way of file handling: with open('./keras-facenet-h5/model.json', 'r', newline='') as f: loaded_model_json = f.read() self._model = model_from_json(loaded_model_json)

Please ensure that packages on your setup match with coursera jupyter environment. For this assignment, tensorflow version is 2.3.0. Don’t worry too much about the pythonic way of doing things. For learning purposes, the snippet of code provided as part of starter code is sufficient. Happy learni…

tensorflow==2.20.0. How to regenerate or where can I get the model’s .json file which works with the latest versions of the ecosystem?

Please wait for the staff to provide more details on your ask.

[image] khteh: where can I get the model’s .json file which works with the latest versions of the ecosystem? Not available. The courses are intended to be run on the Coursera platform.

None of this is helpful at all. Where / how did the coursework get the serialized model json file?

The course is five years old at least. The folks who created that assignment are (likely) long gone - or more certainly, aren’t reading the forums.

You are telling the community here “don’t take the course!” as it is outdated. The current staff spend no effort in maintaining and upkeeping the content of the course! Spend your money wisely elsewhere!

[image] khteh: You are telling the community here “don’t take the course!” Not at all. You may misunderstand the message here. Going beyond the provided platform is left for the student to undertake. The course is entirely valid and useful as presented. That the ML industry doesn’t see any …
