ValueError: Unknown optimizer: Custom>Adam #1075

Closed ist00dent closed 8 months ago

ist00dent commented 8 months ago

I encounter this error, I mainly try the code in Google Colab in order to know if everything is correct, but when I put it in python file in android studio, it has this error, neither .tflite nor .h5 is working

Chaquopy version

plugins { id 'com.android.application' version '8.0.2' apply false id 'com.android.library' version '8.0.2' apply false id 'com.chaquo.python' version '14.0.2' apply false }

Devices or emulators where the issue happens

Relevant parts of your code

It redirects me in this lines

in java file

module = python.getModule("token_helper");

in python file

model_path = join(dirname(file), 'lstm_model.h5')

Describe your issue

I add compile = False when calling load_model() and it works
