I don’t understand the meaning of this message from the grader ,"model in your submission is invalid. Please try again!'. I zipped all the required files and submitted them.

they said that using TensorFlow < 2.0 would work, but it didn’t work for me

open model.json in your favourite code editor, change the value :
generatedBy : “keras v2.2.0-tf”
keras_version : “2.2.0-tf”

You dont need to re-train the model

Hi, I am using colab with keras v2.11.0 and TensorFlow.js Converter v4.2.0. I am also getting INVALID SUBMISSION, even though I have model.json and 10 group files. Do you have any ideas?

I tried this, but it didn’t work for me.
