Help! Could not find variable learning_rate

Keras

I am currently training something and the code works well with Tensorflow==2.8.0.
I want to use some functions in Tensorflow==2.13.1, so I change the env and it raises the following errors:
My experimental platform: Ubuntu18.04, CUDA11.7, Tensorflow2.13.1

    File "trainingXXX.py", line XXX, in <module>

      model = model_XXX.get_model()
    File "trainingXXX.py", line XXX, in model_XXX
      return self.XXX_model()
    File "/home/XXX/anaconda3/envs/XXX/lib/python3.8/site-packages/keras/src/optimizers/adam.py", line 120, in __init__

      return tf.Variable(

I have totally no idea why is this case. May someone offer me some advice? Thanks a lot.

Hi @ZWWW, It is very difficult to help as you don’t provide code.
I’m not sure I understand I change the env.
Can you also show how your import keras and or Tensorflow packages?
Thank you.
