Today, I debugged the code and found this error. The complete contents are as follows:
RuntimeError: Cannot clone object < keras. wrappers. scikit_ learn. KerasClassifier object at 0x000003A783733F33>, as the constructor either does not set or modifies parameter layers
No error is reported when the code is found. It is normal
The code is then investigated:
from keras.wrappers.scikit_learn import KerasRegressorChange to:
from tensorflow.keras.wrappers.scikit_learn import KerasRegressorProblem solved!
