Getting error when converting emotions mobilenet model to tensorflow lite #52

Closed quanlt2 closed 1 month ago

quanlt2 commented 1 month ago

Hello, First thank you for your work on this repo. I got an error when running file to_tflite.py in mobile_app folder on my Mac. Here is steps which I did:

  1. clone the repo
  2. create env by virtualenv (python3.9)
  3. install tensorflow: python3 -m pip install tensorflow
  4. cd mobile_app
  5. python3 to_tflite.py

I got the error log: (env) Quans-Mac mobile_app % python3 to_tflite.py 2024-09-26 10:08:17.568254: I tensorflow/core/platform/cpu_feature_guard.cc:210] This TensorFlow binary is optimized to use available CPU instructions in performance-critical operations.

Any idea for fix? Thank you

It seems that this issue is caused by some new inconsistencies with latest version of Tensowrlow and Keras. I did not install them but I simply found an advice in the Tensorflow issue to use the following code:

!pip install -U tf_keras # Keras 2
import os
os.environ["TF_USE_LEGACY_KERAS"] = "1"

I downgrade the TensorFlow version from 2.16.2 to 2.13.1 yesterday and it works like charms. Perhaps the reason as you tell above, so i think you the code should be migrated soon to new version of TensorFlow Thank you for your great work on this repo
